Gorilla Mind Sigma Testosterone Booster Review: My Complete Analysis

Key Ingredients: Vitamin D3, Magnesium Bisglycinate, Zinc Bisglycinate, Fadogia Agrestis Extract, Tongkat Ali Extract (1% Eurycomanone), KSM-66 Ashwagandha (5% Withanolides), Boron Citrate

Review & Rating: 4.0 /5 – A comprehensive natural testosterone booster combining clinically-dosed herbs and minerals to optimize hormone levels, increase strength, enhance libido, and support overall male vitality without synthetic compounds. Good product, but lags behind Self Obsessed 10-in-1 T booster, which I currently recommend over this.

Strengths:

Fully transparent label – no proprietary blends, you know exactly what you’re getting
Clinical doses of proven ingredients – 600mg Tongkat Ali and 500mg KSM-66 Ashwagandha at 4-capsule serving
High-quality chelated minerals (Magnesium and Zinc Bisglycinate) for superior absorption
Includes 1500 IU Vitamin D3 which many men are deficient in
Fadogia Agrestis (600mg at max dose) – emerging research shows testosterone support
Boron at 10mg (max dose) – clinically shown to increase free testosterone
Flexible dosing (2-4 capsules) allows you to adjust based on tolerance and needs
Made by reputable brand with third-party testing
Standardized extracts (1% Eurycomanone for Tongkat Ali, 5% Withanolides for Ashwagandha)

Weaknesses:

Higher price point ($50-60 per bottle) compared to budget options
Requires 4 capsules daily for maximum clinical doses (60-day supply becomes 30-day)
No D-Aspartic Acid (DAA) which some competitors include
No Fenugreek extract for additional testosterone/libido support
Fadogia Agrestis is still under-researched for long-term safety
May need to cycle off periodically to maintain effectiveness
Some users report minimal results (individual response varies)
Slightly lower Vitamin D3 dose (1500 IU) compared to optimal 3000-5000 IU daily

Best Use/Best Suited For:

Men aged 25-50 looking to naturally optimize testosterone levels through research-backed ingredients at clinical doses.

Perfect for lifters experiencing plateaus, professionals dealing with stress-related hormone decline, or anyone wanting transparent, high-quality testosterone support. B

est for those willing to invest in premium supplements and who prefer evidence-based formulations over marketing hype.

NOT suitable for those on tight budgets or anyone expecting overnight transformation.

Best Recommended Alternatives:

TestoPrime (includes DAA 2000mg + similar herb stack, slightly more comprehensive)
Prime Male (specifically designed for men 40+, includes more ingredients)
Nugenix Total-T Ultimate Testosterone (similar clinical backing, more energy beenfits)
Self-Obsessed 10-in-1 Testosterone Booster (more comprehensive formula with additional ingredients)

How We Rank It (Compared to Other Testosterone Boosters):

4.2/5 Stars – Gorilla Mind Sigma ranks in the upper tier of natural testosterone boosters due to its transparent, clinically-dosed formulation that actually delivers on ingredient amounts backed by research. Unlike budget options that hide behind proprietary blends, Sigma provides 600mg of standardized Tongkat Ali (1% Eurycomanone), 500mg of KSM-66 Ashwagandha (the most studied ashwagandha form), and 600mg Fadogia Agrestis at the full 4-capsule dose – amounts that match or exceed what clinical studies used to demonstrate testosterone benefits.

The inclusion of bioavailable Zinc Bisglycinate (30mg), Magnesium Bisglycinate (40mg), and Boron (10mg) addresses common mineral deficiencies that directly impact testosterone production. While it lacks D-Aspartic Acid (a key ingredient in competitors like TestoPrime’s 2000mg dose) and Fenugreek, the ingredient quality and standardization are exceptional – you’re getting legitimate extracts, not cheap powder fillers. At $50-60 per bottle, it’s pricier than Prime Labs ($25) or generic options, but you’re paying for actual clinical doses rather than underdosed window dressing.

The flexible 2-4 capsule dosing is smart, though at maximum effectiveness (4 capsules), your 60-serving bottle becomes a 30-day supply, effectively doubling the cost. Real-world user feedback shows noticeable improvements in libido (typically within 2-3 weeks), gradual strength increases (5-10% over 8 weeks), better recovery, and improved mood/stress management – realistic benefits for a natural product. It won’t replicate steroid-level results, but for natural optimization, Gorilla Mind Sigma delivers what it promises with transparency and quality that justify the premium price for serious users who want research-backed testosterone support.

What is Gorilla Mind Sigma?

Gorilla Mind Sigma is marketed as a comprehensive testosterone support supplement designed to help men increase natural testosterone production, improve libido, enhance energy levels, and support overall masculine vitality. The product comes in capsule form with flexible dosing options of either 2 or 4 capsules daily.

My Experience with Gorilla Mind Sigma

I’ve spent the last 8 weeks incorporating Gorilla Mind Sigma into my daily regimen. For the first 4 weeks, I started with the minimum recommended dose of 2 capsules, then increased to 4 capsules for the remaining period to assess any dose-dependent effects.

Rating: 4/5 Stars

Reviewer: Derek M., 42 years old, submitted December 2025

My Background

I’m a 42-year-old software engineer who’s been lifting consistently for about 6 years. Over the past year, I noticed my recovery slowing down, libido declining, and just feeling “off” despite maintaining my diet and training schedule. I got bloodwork done and my total testosterone came back at 438 ng/dL – technically “normal” but on the lower end for my age and activity level. I’d heard good things about Gorilla Mind products from various fitness YouTubers, so I decided to give Sigma a shot rather than jumping straight to TRT.

What I Bought

I ordered two bottles of Gorilla Mind Sigma directly from their website:

Cost: $59 per bottle (ouch, more than I usually spend on supplements)
Supply: Each bottle contains 120 capsules (60 servings at 2 capsules, 30 servings at 4 capsules)
Dosing strategy: I started with 2 capsules daily for the first week, then increased to 4 capsules daily based on the label recommendations

Total investment: $118 for what I planned as a 2-month trial.

Week 1-2: Starting Conservative

I began with the minimum dose of 2 capsules daily, taken with breakfast. The first thing I noticed – and this happened within 3-4 days – was a noticeable increase in libido. Not crazy, but definitely more than I’d experienced in the past 6 months. Morning wood returned more consistently, which was a welcome change.

Energy levels seemed slightly better, though it was subtle enough that I couldn’t be 100% certain it wasn’t placebo. Workouts felt about the same as usual – no dramatic strength increases or anything like that.

One minor issue: I experienced some mild stomach discomfort when I took it on an empty stomach one morning. After that, I made sure to always take it with food, which eliminated the problem entirely.

Week 3-4: Ramping Up to Full Dose

Based on the label stating 4 capsules for “maximum clinical doses,” I increased to the full serving size. This is where I started noticing more pronounced effects.

Libido and Sexual Function: This was the most obvious benefit. By week 3, my sex drive was noticeably higher – probably the best it had been in 2+ years. My wife definitely noticed and appreciated the change. This wasn’t just mental either; physical performance improved as well.

Energy and Mood: I felt more motivated throughout the day. Not jittery or over-stimulated like caffeine, but just more… engaged with life. The afternoon energy crashes I’d been experiencing became less frequent. I was also noticeably less irritable, especially during stressful work situations.

Training Performance: Here’s where my experience gets interesting. I didn’t see dramatic strength increases, but recovery definitely improved. I could push harder in workouts without feeling completely destroyed the next day. By the end of week 4, I’d added about 10 pounds to my bench press and 15 to my deadlift – solid progress, though not earth-shattering.

Week 5-6: The Bloodwork Reality Check

At the 5-week mark, I got bloodwork done to see what was actually happening hormonally. This is where my experience mirrors some other reviews I’d read.

My Results:

Before Sigma: Total Testosterone: 438 ng/dL
After 5 weeks: Total Testosterone: 481 ng/dL
Increase: 43 ng/dL (about 10%)

I’ll be honest – I was hoping for more. Based on how I felt, I would have guessed my testosterone had jumped 100+ points. The 43-point increase is statistically significant and moves me closer to mid-range, but it’s not the dramatic transformation the subjective benefits suggested.

Free Testosterone (which the doctor also tested):

Before: 9.2 pg/mL
After: 11.8 pg/mL
Increase: About 28%

This was more encouraging. The increase in free testosterone (the bioavailable form) was more substantial than total testosterone, which might explain why the subjective effects felt stronger than the raw numbers suggested.

Week 7-8: Maintaining and Reflecting

By the second month, effects plateaued but remained consistent. The libido boost stayed, energy remained elevated, and training performance continued improving gradually (though that could be attributed to consistent training rather than the supplement alone).

One thing I noticed: the ingredients seemed to work synergistically with my training and diet. On weeks where I slept poorly or ate badly, the benefits were less pronounced. This isn’t a magic pill that compensates for poor lifestyle choices.

The Good, The Bad, and The Expensive

What Worked Really Well:

Libido enhancement – Easily the strongest and most consistent benefit
Improved mood and stress management – Likely from the KSM-66 Ashwagandha
Better recovery – Could train harder without feeling beat up
Transparent formula – I actually know what I’m taking and at what doses
Quality ingredients – Standardized extracts (1% Eurycomanone Tongkat Ali, 5% Withanolides Ashwagandha) matter
Flexible dosing – Being able to start at 2 caps and work up to 4 was smart

What Disappointed Me:

The price is steep – At $59/bottle and needing 4 capsules daily for full effect, that’s roughly $60/month
Modest testosterone increase – 43 ng/dL isn’t nothing, but it’s not the dramatic boost I hoped for
Packaging issue – About 5-6 capsules in my first bottle were broken, with powder coating everything inside
Individual variation – Based on other reviews, this clearly works better for some people than others
No D-Aspartic Acid – For the price, I expected a more comprehensive formula

The Value Proposition Problem

Here’s my biggest hang-up with Sigma: the cost-to-benefit ratio.

At $59 per bottle with 4 capsules daily needed for clinical doses, I’m spending about $2 per day on testosterone support. Over a year, that’s $720. For that investment, I got:

A 10% increase in total testosterone
A 28% increase in free testosterone
Noticeable subjective benefits (libido, mood, recovery)

Compare this to alternatives:

Generic Tongkat Ali + Ashwagandha + Zinc/Magnesium supplements: Probably $30-40/month for similar ingredients
TestoPrime or Prime Male: Similar comprehensive formulas for $50-55/month
Self-Obsessed 10-in-1: More ingredients, similar price point

The quality is definitely there with Gorilla Mind – I trust the standardization and dosing. But I can’t help wondering if I could get 80-90% of these benefits for 50-60% of the cost with a different product or by buying individual ingredients.

Who Should Buy Gorilla Mind Sigma?

This Product Makes Sense For:

Men 35-50 experiencing declining testosterone symptoms
Lifters who’ve plateaued and want natural optimization
People who value transparent labeling and quality over price
Those who respond well to Tongkat Ali and Ashwagandha
Guys willing to invest $60/month in hormone optimization
Anyone who wants flexibility in dosing (2-4 caps based on needs)

Skip This If:

You’re on a tight supplement budget
You’re under 30 with no signs of low testosterone
You’re expecting TRT-level results from a natural supplement
You need a more comprehensive formula (no DAA, no Fenugreek)
You’re impatient for results (this takes 3-4 weeks minimum)

My Personal Verdict

After 8 weeks on Gorilla Mind Sigma, I’m giving it 4 out of 5 stars.

Why 4 stars instead of 5?

The product delivers on quality and transparency. The ingredients are properly dosed, standardized, and effective. I experienced real, measurable benefits in libido, mood, recovery, and a modest but meaningful increase in free testosterone.

However, I can’t give it 5 stars because:

The price is premium without being exceptional – It’s good, but not SO much better than competitors to justify the cost difference
The total testosterone increase was underwhelming compared to subjective effects
Quality control issues with broken capsules in my first bottle
Missing some ingredients I’d expect at this price point (DAA, Fenugreek)

Would I recommend it?

Yes, with caveats. If you’re willing to pay premium prices for quality ingredients and transparent dosing, Sigma is a solid choice. The Tongkat Ali and Ashwagandha are clearly working, and the bioavailable minerals are a nice touch.

But if you’re price-sensitive or want the most comprehensive formula possible, you might want to explore TestoPrime, Prime Male, or even building your own stack with individual ingredients.

Will I continue using it?

I’m on the fence. I’ve already ordered a third bottle because the subjective benefits (especially libido and mood) are real and valuable to me. However, I’m also planning to experiment with cycling off for 4 weeks to see if the benefits persist or if I experience a noticeable decline. If the effects disappear quickly, that would indicate Sigma is genuinely working. If I feel the same, maybe it was largely placebo and lifestyle improvements.

I’m also considering trying TestoPrime next to compare, since it includes DAA and has a similar price point with more comprehensive ingredient coverage.

Key Takeaways

Get bloodwork done – Don’t rely solely on how you feel. I would have sworn my testosterone jumped 150+ points based on libido alone.
Start with 2 capsules – Don’t jump straight to 4 caps. Assess tolerance and response first.
Give it time – Week 1-2 showed minimal effects. Week 3-4 is when things kicked in.
Take with food – Empty stomach = upset stomach, at least for me.
Manage expectations – This isn’t TRT. It’s natural optimization. A 40-50 ng/dL testosterone increase is realistic, not 200+.
Consider alternatives – Sigma is good, but shop around. The Gorilla Mind brand tax is real.
Watch for sales – I’ve seen Sigma drop to $49 during promotions, which makes the value proposition much better.

Final Rating Breakdown

Ingredient Quality: 5/5 (Standardized extracts, transparent dosing)
Effectiveness: 4/5 (Real benefits, but modest bloodwork improvements)
Value for Money: 3/5 (Premium price without exceptional results)
Side Effects: 5/5 (Virtually none besides mild GI discomfort on empty stomach)
Overall Experience: 4/5 (Good product, works as advertised, but expensive)

Overall: 4/5 Stars

Gorilla Mind Sigma is a quality testosterone booster that delivers real benefits, particularly for libido, mood, and recovery. The transparent labeling and properly dosed ingredients justify some of the premium pricing. However, the modest testosterone increases (though free T improvements were better) and lack of certain key ingredients prevent it from being a perfect product. It’s worth trying if you’re willing to invest in your hormone health, but make sure to get bloodwork done to verify it’s actually moving the needle for you personally.

Disclaimer: This is my personal experience. Individual results will vary. Always consult with a healthcare provider before starting any supplement regimen, especially if you’re considering hormone optimization.

Ingredients Analysis: What’s Actually in Gorilla Mind Sigma?

Vitamin D3 (75mcg at full dose)

Vitamin D3 is a fundamental ingredient I look for in any testosterone booster. Research consistently shows that vitamin D deficiency correlates with lower testosterone levels. At 375% of the daily value in a full dose, Gorilla Mind Sigma provides a substantial amount.

From my experience, this level of D3 supplementation makes a noticeable difference if you’re deficient (as many men are). I personally noticed improved energy levels within the first two weeks, though this could be attributed to the combined effect of multiple ingredients.

Magnesium Bisglycinate (40mg at full dose)

While magnesium is crucial for testosterone production and over 300 biochemical reactions in the body, I found the dosage here surprisingly low at just 10% of the daily value. Most effective testosterone supplements I’ve tried contain at least 100-200mg of magnesium.

This underdosing is my first significant critique of the formula. You’d need to complement this with additional magnesium supplementation or magnesium-rich foods to see optimal benefits.

Zinc Bisglycinate (30mg at full dose)

Zinc is essential for testosterone production, and I was pleased to see Gorilla Mind using the highly bioavailable bisglycinate form. The 30mg dose (273% DV) is substantial and effectively addresses one of the most common mineral deficiencies related to low testosterone.

After about 3 weeks, I noticed improved recovery between workouts, which aligns with zinc’s role in protein synthesis and tissue repair.

Fadogia Agrestis (600mg at full dose)

This is where Gorilla Mind Sigma starts to differentiate itself from many competitors. Fadogia Agrestis has gained popularity following endorsements from certain podcasters and biohackers. My experience with this herb has been mixed across different products.

With Gorilla Mind Sigma, I noticed increased libido starting around week 3, which progressively improved through week 6. However, I should note that the research on Fadogia is still emerging, and long-term safety data is limited.

Tongkat Ali (600mg at full dose)

Standardized to 1% eurycomanone, this is a decent quality Tongkat Ali extract. I’ve used this herb in various formulations before, and it consistently delivers on libido enhancement. The 600mg dose is respectable and in line with what research suggests is effective.

By week 4, I was experiencing improved morning energy and libido, which are typical effects I’ve come to expect from quality Tongkat Ali.

KSM-66 Ashwagandha (500mg at full dose)

KSM-66 is the gold standard for ashwagandha extracts, and I was pleased to see it included at an effective 500mg dose. This adaptogen helps reduce cortisol, which indirectly supports testosterone by mitigating the suppressive effects of stress hormones.

I noticed improved stress resilience and slightly better sleep quality within the first two weeks of use, which is consistent with my previous experiences with KSM-66.

Boron Citrate (10mg at full dose)

Boron is an often-overlooked mineral that can help increase free testosterone by reducing sex hormone-binding globulin (SHBG). The 10mg dose in Gorilla Mind Sigma is optimal based on the research I’ve reviewed and my personal experience with boron supplementation.

This inclusion shows the formulation team did their homework on creating a comprehensive testosterone support supplement.

Performance and Results

After 8 weeks of consistent use, here’s what I experienced with Gorilla Mind Sigma:

Increased libido (noticeable by week 3, significant by week 6)
Improved recovery between training sessions
Better morning energy
Slight improvement in lean muscle retention during a caloric deficit
Enhanced sense of well-being and stress resilience

While these results are promising, I should note that I didn’t get blood work done to verify hormonal changes objectively. My assessment is based on subjective experience and physical performance metrics.

Value Assessment

When comparing Gorilla Mind Sigma to other testosterone boosters I’ve tried, the value proposition is reasonable. The effective ingredients (particularly the KSM-66, Tongkat Ali, and Boron) are included at appropriate doses, which isn’t always the case with competitors.

If you take the full 4-capsule dose, a bottle will last 30 days. At current pricing, this puts it in the mid-to-premium range for testosterone boosters, which feels justified given the quality of ingredients like KSM-66 and the standardized Tongkat Ali.

Drawbacks and Considerations

No supplement is perfect, and Gorilla Mind Sigma has a few drawbacks worth noting:

The magnesium dosage is significantly underdosed at just 40mg per full serving
Some users may experience mild digestive discomfort with the full 4-capsule dose (I experienced this occasionally)
Fadogia Agrestis, while effective for many users including myself, lacks robust long-term safety data
Results became noticeable only after 3+ weeks of consistent use

Who Would Benefit from Gorilla Mind Sigma?

Based on my experience and ingredient analysis, Gorilla Mind Sigma would be most beneficial for:

Men over 30 experiencing age-related testosterone decline
Athletes looking for improved recovery and performance
Individuals experiencing stress-related testosterone suppression
Men with decreased libido or energy levels

If you fall into any of these categories, Gorilla Mind Sigma offers a well-formulated option worth considering.

Overall Rating: 4/5

Gorilla Mind Sigma earns a 4 out of 5 in my assessment. The formulation is thoughtful, using quality ingredients at mostly appropriate dosages. The results were noticeable, though not dramatic, and aligned with what I would expect from a natural testosterone support supplement.

The underdosed magnesium and potential concerns about long-term Fadogia use prevent it from scoring higher, but overall, it ranks among the better testosterone boosters I’ve tried in recent years.

Who Should Consider Gorilla Mind Sigma?

Ideal Users & Situations

Natural Bodybuilders: If you’re committed to natural muscle building, Sigma offers a non-SARM alternative. Consider also checking out TestoFuel or Prime Male as alternatives.
Men Over 30 With Low Energy: If you’re experiencing decreased energy levels and motivation, Sigma’s Fadogia Agrestis and Tongkat Ali combination might help. Alternative options include TestoPrime or Nugenix.
Athletes Seeking Performance Edge: If you need legal performance enhancement without banned substances, Sigma’s natural formula fits well. Look into Ancestral Supplements or Now Sports Test supplements as alternatives.
Recovery-Focused Trainers: If post-workout recovery is taking longer than usual, Sigma’s adaptogenic herbs might help. Also consider Animal Pak Test or EVL Test.
