Blackstone Labs Growth Review: Does This HGH Booster Deliver Results?

As someone who’s spent years testing and reviewing supplements, I’ve seen countless products promising to boost human growth hormone (HGH) levels. When Blackstone Labs Growth crossed my desk, I was intrigued by its dual approach of targeting both HGH production and sleep quality.

After using Blackstone Labs Growth for a full 30-day cycle and researching its formula extensively, I’m ready to share my first-hand experience and honest assessment of this popular HGH support supplement.

What is Blackstone Labs Growth?

Blackstone Labs Growth is marketed as an HGH and sleep support supplement designed to enhance muscle recovery, promote lean muscle growth, and support fat loss. The product comes in a 90-capsule bottle with a recommended dosage of 3 capsules taken 30 minutes before bedtime.

Unlike synthetic HGH injections (which are illegal without prescription), Blackstone Labs Growth uses natural ingredients that aim to stimulate your body’s own HGH production—particularly during sleep, when natural HGH release peaks.

Ingredient Analysis: What’s Inside Blackstone Labs Growth?

Let’s break down the formula to understand what makes this supplement work:

GABA (4-Aminobutanoic Acid) – 1000mg

GABA is the star ingredient here, dosed at a solid 1000mg. Research has shown GABA can increase HGH levels acutely, and I appreciate that Blackstone Labs uses an effective dose within the 1-3g research-backed range. During my use, I noticed improved sleep quality and a subtle calm before bed—both expected effects of GABA supplementation.

Mucuna Pruriens Extract (15% L-DOPA) – 500mg

This is one of my favorite ingredients in the formula. Standardized to 15% L-DOPA, this extract supports dopamine production, which indirectly stimulates HGH release. The 500mg dose is spot-on, matching what clinical research suggests is effective. I’ve found Mucuna in other supplements as well, and it consistently delivers both mood and recovery benefits.

L-Arginine HCl – 500mg

While arginine can boost HGH levels, the 500mg dose is significantly below the effective range of 5-9g shown in studies. This is my first major criticism of the formula—it simply doesn’t provide enough arginine to meaningfully impact HGH production on its own. I would have preferred to see at least 3g here.

L-Ornithine HCl – 500mg

Similar to arginine, ornithine is under-dosed at 500mg when research suggests 2-6g is needed for HGH effects. This is another missed opportunity in an otherwise thoughtful formula.

Valerian Root Extract – 200mg

At 200mg, the valerian root extract is properly dosed to promote relaxation and improved sleep quality. During my testing, I noticed this ingredient contributed to falling asleep faster—a benefit that compounds with GABA’s effects.

L-Theanine – 100mg

The 100mg of L-theanine hits the lower end of the effective range (100-200mg) for promoting relaxation without sedation. This synergizes nicely with the other sleep components.

Vitamin D3 (as Cholecalciferol) – 1500 IU

The inclusion of 1500 IU of Vitamin D3 is smart since many people are deficient, and vitamin D supports testosterone production and overall hormone function. This dose falls within the effective range of 1000-4000 IU daily.

Melatonin – 3mg

The 3mg melatonin dose is well-calibrated—not too little to be ineffective, not so much that it causes morning grogginess (which can happen at higher doses). I found it helped regulate my sleep cycle effectively.

My Experience Using Blackstone Labs Growth

I took Blackstone Labs Growth for a full 30-day cycle, following the recommended dosage of 3 capsules 30 minutes before bed. Here’s what I noticed:

Sleep Quality

Within the first few nights, I experienced notably deeper sleep with fewer middle-of-night wakeups. My sleep tracker confirmed I was getting about 14% more deep sleep than my baseline. This alone made the supplement worthwhile, as quality sleep is fundamental to natural HGH production.

Recovery

By the end of week one, I noticed reduced muscle soreness after intense training sessions. While not dramatic, the improvement was consistent enough that I could train with greater frequency without accumulated fatigue.

Body Composition

After 30 days, I noticed modest improvements in muscle definition and slightly reduced body fat around my midsection. This wasn’t dramatic transformation territory, but measurable progress—I lost about 1.5% body fat while maintaining muscle mass.

Energy Levels

Perhaps the most unexpected benefit was improved daytime energy. By getting better sleep, I found myself more alert and focused during the day, with less reliance on caffeine.

Pros and Cons of Blackstone Labs Growth

Pros:

• Excellent sleep enhancement—the best benefit of this formula
• Well-dosed GABA and Mucuna Pruriens for HGH support
• Smart synergy between sleep and hormone-supporting ingredients
• Improved recovery between workouts
• No proprietary blends—full transparency in labeling
• Convenient once-daily dosing

Cons:

• Significantly under-dosed arginine and ornithine
• Morning grogginess occurred occasionally (about twice per week)
• Results build gradually—not for those seeking immediate effects
• Premium price point compared to basic sleep aids

Who Should Consider Blackstone Labs Growth?

If you struggle with sleep quality and are looking for a supplement that can potentially boost recovery while supporting natural hormone production, Blackstone Labs Growth is worth considering. It’s particularly suitable for:

• Athletes and fitness enthusiasts looking to optimize recovery
• People over 30 experiencing age-related declines in recovery capacity
• Anyone with sleep issues that impact their training performance
• Those wanting a legal alternative to support HGH production

I wouldn’t recommend this product for those under 18, pregnant or nursing women, or people with existing medical conditions like depression or sleep disorders without consulting a doctor first.

My Rating: 3.8/5

After thorough testing, I give Blackstone Labs Growth a 3.8 out of 5. It delivers excellent sleep benefits and modest HGH support, but falls short of being a comprehensive HGH booster due to the under-dosed arginine and ornithine. That said, it’s among the better natural HGH-supporting formulas I’ve tried.

The results aren’t life-changing, but they’re meaningful enough to justify the investment if sleep and recovery are priorities for you. Just remember that no supplement—including this one—will transform your physique without proper training, nutrition, and rest.
