GenF20 Plus is our top pick among HGH-releaser supplements: tablets plus an oral spray, with tablet amounts published, a written 67-day guarantee and one small placebo-controlled trial (its main IGF-1 result was not significant). GenFX is a tablet-only amino acid formula with no published trial, and we couldn’t verify its label amounts or guarantee terms.
⚡ Quick Verdict
GenF20 Plus is our top pick among HGH-releaser supplements. GenFX is the simpler, tablet-only alternative, but read its actual label and refund terms before buying. Scroll down for the full side-by-side breakdown.
Our Top Pick Among HGH-Releaser Supplements: GenF20 Plus
GenF20 Plus publishes its tablet amounts and has been tested in one small placebo-controlled trial, though its main IGF-1 result wasn’t significant. The 67-day guarantee requires returns to arrive within 67 days of delivery, and shipping isn’t refunded.
GenF20 Plus is our top pick among HGH-releaser supplements. GenFX is the simpler, tablet-only alternative, but read its actual label and refund terms before buying.
GenF20 Plus is an amino acid tablet and oral spray marketed as an HGH releaser. GenFX is a tablet-only amino acid HGH releaser. See the side-by-side table above and each full review for ingredients, evidence and cautions.
We don’t recommend it. Both are amino acid “HGH releasers” with overlapping ingredients (including arginine and animal-derived extracts), so there’s no reason to stack them.
Buy GenF20 Plus from the official website, which is the surest way to get the genuine product. Money-back guarantee: 67 days from delivery (strict return terms). Marketplace orders may not be covered, so read the official terms before you buy.
Both are over-the-counter dietary supplements, not medicines, and they aren’t intended to diagnose, treat, cure or prevent any disease. Key cautions: for GenF20 Plus, L-arginine and GABA may lower blood pressure, it contains animal-derived ingredients, and it isn’t for anyone with a history of cancer unless their oncologist agrees; for GenFX, its formula is unverified; it’s reported to contain bovine pituitary extract and arginine, which may lower blood pressure. Always consult a qualified healthcare professional before starting any supplement, particularly if you take prescription medication or have a health condition.
