GenF20 Plus is our top pick among HGH-releaser supplements. Provacyl is aimed at men over 40 and contains DHEA, a hormone. Neither is proven to work: GenF20 Plus's one small trial didn't find a significant IGF-1 increase versus placebo overall, and Provacyl has no trial of its own, with most ingredients at small doses.
⚡ Quick Verdict
Our pick is GenF20 Plus, our top pick among HGH-releaser supplements. Provacyl's DHEA brings prostate cautions and is banned in tested sport, and DHEA didn't show meaningful benefits in a two-year trial in older men at nearly four times Provacyl's dose.
Provacyl is a 4-capsule 'andropause' formula with 20 mg DHEA, D-aspartic acid (300 mg), ZMA, muira puama, ginkgo, chaste berry, ginseng and other botanicals, plus an amino acid portion with no amounts, per a third-party listing we couldn't confirm on the official site. There's no trial of the product, and most doses are well below researched amounts. A 67-day guarantee is advertised (terms not confirmed).
GenF20 Plus is an amino acid tablet plus oral spray 'HGH releaser' from Leading Edge Health. It contains no growth hormone, the tablet amounts are small (for example, 130 mg of L-arginine per serving) and the spray's ingredients aren't listed on the official site. In its one 12-week placebo-controlled trial (61 people finished), IGF-1 rose more than on placebo but the difference wasn't statistically significant, and body fat, energy and sleep didn't differ from placebo. It has a 67-day money-back guarantee, counted from delivery.
GenF20 Plus is our top pick among HGH-releaser supplements and our pick in this comparison. Buy from the official site so the 67-day money-back guarantee applies, and keep expectations modest.

Both are dietary supplements, not medicines. Provacyl contains DHEA, which the body can convert to testosterone and estrogen; men with prostate cancer, an enlarged prostate or other hormone-sensitive conditions shouldn't take it without a doctor's advice, and it's banned in tested sport. Its ginkgo may raise bleeding risk, and it contains soy. GenF20 Plus: L-arginine and GABA may lower blood pressure, arginine and chromium can affect blood sugar, it contains animal-derived ingredients (deer antler velvet, bovine colostrum, pituitary powder), and it isn't advised with a history of cancer unless your oncologist agrees.
