When choosing an HGH-releaser supplement, keep expectations low: Mayo Clinic says research doesn't show that supplements claiming to raise HGH work, and the FTC has said it knew of no reliable evidence that pills or sprays raise growth hormone. If you still want to try one, check whether the product itself has been tested and what the trial found, whether amino acid doses are disclosed and how they compare with research amounts, and the guarantee terms. GenF20 Plus is one of the few with a published product trial, but its main IGF-1 result was not statistically significant.
Natural HGH Support vs Synthetic HGH
Synthetic HGH (somatropin) is a prescription-only drug with significant side effect risks, and in the US it's illegal to use it for conditions the FDA hasn't approved. "HGH supplements" contain no growth hormone. They are amino acid and herbal blends marketed as helping the pituitary release more of its own growth hormone, an effect that hasn't been shown at the doses these products contain. They are over-the-counter dietary supplements, not hormones.
What to Look for in an HGH Supplement
A trial of the product, and what it found: GenF20 Plus has one (2015, 61 completers), but IGF-1 did not rise significantly versus placebo overall; a significant result appeared only in a post hoc analysis of people aged 40 and over
Amino acid doses: arginine has raised growth hormone in studies using several grams, while HGH products typically contain a few hundred milligrams or less (GenF20 Plus lists 130 mg per serving, HyperGH 14x 520 mg a day)
Disclosed doses: if amounts aren't listed (as with the oral sprays of GenF20 Plus and HyperGH 14x), you can't check them
Spray claims: there's no evidence an oral spray improves absorption
Guarantee terms: many run 67 days from delivery and require returning containers by a deadline
Red Flags in HGH Products
Claims of 'HGH' on the label — actual HGH requires prescription

Check whether the product has been tested and what the trial actually found, compare disclosed amino acid doses with research amounts, avoid proprietary blends and read the guarantee terms. GenF20 Plus has one published trial, with mixed results.
There's little evidence they do. Mayo Clinic says research doesn't show that supplements claiming to raise HGH work, and GenF20 Plus's own trial found no significant IGF-1 increase versus placebo across all participants. They are not comparable to prescription HGH.
GenF20 Plus has one published placebo-controlled trial (2015). IGF-1 rose more on GenF20 Plus than placebo, but not significantly across all 61 participants; a significant result appeared only in a post hoc analysis of people aged 40 and over, and growth hormone itself wasn't measured.
IGF-1 (insulin-like growth factor 1) is a blood marker that reflects growth hormone activity, and it's the main outcome HGH supplement trials measure.
They're marketed for different targets: HGH supplements claim to support growth hormone release, and testosterone boosters claim to support testosterone. Evidence is limited in both categories, and neither replaces medical testing if you suspect a hormone problem.
