HGH-Releaser Supplements We Cover, Ranked (2026)

Introduction: Why This Category Matters

Growth hormone levels fall with age, and "HGH releaser" supplements claim to help the body make more using amino acids and other ingredients. None of them contains growth hormone. Mayo Clinic says research doesn't show that supplements claiming to raise HGH work, and in 2005 the FTC said it knew of no competent evidence that HGH pills or sprays raise growth hormone. This guide compares the five products we've reviewed. For how they differ from prescription treatment, see HGH supplements vs HGH injections.

For each product we check the current formula and disclosed doses, whether the product itself has been tested in a published trial, what the ingredient research shows, the guarantee terms and the main safety cautions. We earn affiliate commissions on purchases made through our links, as disclosed above.

Our Top Pick: GenF20 Plus

Amino acid tablet and oral spray 'HGH releaser' from Leading Edge Health. Tested in one small 2015 trial whose main IGF-1 result was not significant. Formula details, the evidence, guarantee terms and cautions are in its section below.

How to Evaluate Products in This Category

Before looking at individual products, these are the checks that matter most:

• Dose alignment with published research: An ingredient at a fraction of the studied dose is unlikely to match the research. Check whether the label discloses each dose and compare it with the amounts used in human studies.
• Published human evidence: Look for a published, placebo-controlled trial of the product itself. Most products in this category have none and rely on ingredient studies, animal data or traditional use.
• Branded ingredients: Branded extracts (such as KSM-66, Sensoril, Cognizin, Furosap or SYN-COLL) are standardized, and some have their own studies, often funded by the supplier. A brand name alone doesn't mean the product uses a studied dose.
• Manufacturing and testing: Supplements sold in the US must be made under the FDA's current good manufacturing practice (cGMP) rules. An independent certificate of analysis is a useful extra check on purity and dose.
• Refund terms: Read the conditions, not just the number of days. Many guarantees require containers to reach the warehouse within the window and don't refund shipping.

#1 — GenF20 Plus — Detailed Analysis

Top pick: HGH-releaser supplements (weak evidence) | 67-Day Money-Back Guarantee (seller's terms apply)

Amino acid tablet and oral spray 'HGH releaser' from Leading Edge Health. Tested in one small 2015 trial whose main IGF-1 result was not significant.

GenF20 Plus suits a healthy adult who wants to try an HGH releaser with a real refund policy and is comfortable with modest expectations. Its one trial did not show a significant IGF-1 increase versus placebo overall, and it never measured growth hormone or showed changes in body fat, energy or sleep.

What We Found

• Formula: Amino acid tablets (L-arginine 130 mg, L-glutamine 115 mg and smaller amounts of other amino acids, plus deer antler velvet, bovine colostrum and pituitary powder) and an oral spray whose ingredients aren't listed on the official site. It contains no growth hormone.
• Evidence: One 12-week placebo-controlled trial of the product (Sonawane et al., 2015; 61 completers). Across all participants the IGF-1 rise was not statistically significant versus placebo, and there was no difference in body fat, energy, sleep or libido. Growth hormone itself wasn't measured.
• Guarantee: 67 days from delivery. Try for 60 days; containers must reach the warehouse within 67 days of delivery, "no exceptions"; shipping is not refunded; one refund per customer.
• Cautions: Not for anyone with a history of cancer unless their oncologist agrees. Contains animal-derived ingredients, so it isn't vegetarian.

#2 — HyperGH 14x — Detailed Analysis

Best for: non-tested gym-goers (weak evidence) | 67-day guarantee advertised (terms not confirmed)

Tablet and oral spray amino acid blend from Leading Edge Health, marketed to lifters as an 'HGH releaser'. No published trial of the product.

HyperGH 14x may appeal to lifters who want an amino acid 'HGH releaser' and can use the money-back guarantee if it does nothing for them. It has no published trial, its doses are well below those used in growth hormone research, and the spray contains an undisclosed amount of levodopa-containing Mucuna.

What We Found

• Formula: Tablets (L-arginine 520 mg a day, other amino acids, tribulus, astragalus, deer antler velvet, colostrum and pituitary powder) plus an oral spray with undisclosed amounts, including Mucuna pruriens. It contains no growth hormone.
• Evidence: No published trial of HyperGH 14x. Arginine has raised growth hormone in studies using several grams; this product lists 520 mg a day.
• Guarantee: 67 days from receiving the order per a 2025 company-sourced press release; not confirmed on the official site.
• Cautions: The spray's Mucuna contains levodopa: avoid it with Parkinson's drugs, MAO inhibitors or antidepressants unless a doctor agrees. Deer antler velvet may contain IGF-1, which is banned in tested sport.

#3 — Provacyl — Detailed Analysis

Aimed at men over 40 (contains DHEA) | 67-day guarantee advertised (terms not confirmed)

A 4-capsule men's 'andropause' formula containing DHEA, D-aspartic acid, ZMA, muira puama, ginkgo, ginseng and other botanicals, plus an unquantified amino acid blend. It has no clinical trial of its own.

Provacyl may appeal to a man who wants a broad 'andropause' formula, but it is a long list of mostly small doses plus 20 mg of DHEA, and none of it has been tested as a product. Because DHEA is a hormone, men with prostate or other hormone-sensitive conditions, and tested athletes, should avoid it unless a doctor advises otherwise.

What We Found

• Formula: Per 4-capsule serving (third-party listing): D-aspartic acid 300 mg, ZMA 215 mg, muira puama 150 mg, ginkgo 125 mg, chaste berry 125 mg, ginseng 100 mg, DHEA 20 mg and other small amounts, plus an amino acid blend with no amounts given.
• Evidence: No trial of Provacyl. DHEA at 75 mg a day (nearly four times this dose) didn't improve body composition, performance or quality of life in a two-year placebo-controlled trial of older men.
• Guarantee: 67-day money-back guarantee per third-party listings; exact conditions unverified.
• Cautions: Contains DHEA, a hormone: men with prostate cancer, an enlarged prostate or other hormone-sensitive conditions should avoid it unless a doctor advises otherwise. DHEA is banned in tested sport.

#4 — GenFX — Detailed Analysis

Lower-cost HGH alternative | Refund terms unverified

Tablet-only amino acid 'HGH releaser' marketed to men and women. No published trial; ingredient amounts not disclosed in sources we could check.

GenFX is a tablet-only amino acid 'HGH releaser' for adults who want a simpler alternative to GenF20 Plus. It has no published trial and we could not verify its label, doses or guarantee terms, so read the actual label and refund policy before buying.

What We Found

• Formula: Unverified. Affiliate pages list amino acids (L-arginine, L-glutamine, L-glycine, L-lysine, L-ornithine and others), Chinese ginseng and bovine pituitary; no source we could open gives amounts.
• Evidence: No published trial of GenFX. Amino acids have raised growth hormone only at gram-level doses in studies.
• Guarantee: Unverified; read the refund policy before buying.
• Cautions: Read the actual label before use. It is reported to contain bovine pituitary, so it isn't vegetarian.

#5 — GenF20 Muscle — Detailed Analysis

We could not verify GenF20 Muscle's maker, formula, doses or guarantee, and it is no longer offered through our links. Anyone considering it should read the actual label first; HyperGH 14x is the related product currently available, though it also lacks a product trial.

What We Found

• Formula: Unverified. Listed ingredients include L-arginine, L-glutamine, ashwagandha and rhodiola, but we couldn't find an official label or amounts.
• Evidence: No published trial of GenF20 Muscle, and claims that it supports growth hormone are unproven.
• Guarantee: Unverified.

Buying Guide: What to Look For

When evaluating any supplement in this category, check these points before purchasing:

• Full ingredient disclosure, with no proprietary blends hiding individual doses
• Made under FDA cGMP rules, ideally with an independent certificate of analysis
• A refund window long enough for a fair trial, with conditions you've read
• Purchase from the official site if you want to be able to use the money-back guarantee

Safety Considerations

All products discussed in this article are sold as dietary supplements or cosmetics, not medicines. They are not intended to diagnose, treat, cure or prevent any disease. These statements have not been evaluated by the Food and Drug Administration (FDA).

Always consult a qualified healthcare professional before starting any supplement, particularly if you take prescription medication, have an existing medical condition, or are pregnant or breastfeeding. Individual results vary.

Final Recommendation

GenF20 Plus is our top pick because it's the only product here tested in a published trial and its refund terms are clearly stated, but that trial didn't show a significant overall IGF-1 increase versus placebo. If you're considering an HGH supplement, talk to your doctor first, especially if you have a history of cancer. If you buy, use the official site so you can use the money-back guarantee, and read its conditions first.
