GenF20 Plus is our top pick among HGH-releaser supplements; HyperGH 14x is best for people who train. Both come from Leading Edge Health, use amino acid tablets plus an oral spray, and contain no growth hormone. GenF20 Plus has one small 2015 placebo-controlled trial, though its main IGF-1 result wasn't statistically significant. HyperGH 14x lists higher amino acid doses but has no published trial. Neither is proven to raise growth hormone.
⚡ Quick Verdict
Our pick in this comparison is GenF20 Plus, our top pick among HGH-releaser supplements. It's one of the few HGH releasers tested in a published placebo-controlled trial, and its tablet amounts and guarantee terms are published. Keep expectations modest: that trial found no significant IGF-1 rise versus placebo across all participants.
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.
HyperGH 14x is a tablet and oral spray blend from the same company, marketed to people who lift. Its tablets list higher daily amino acid amounts (520 mg of L-arginine a day), though that is still well below the multi-gram doses used in growth hormone research. It has no published trial, and the spray lists Mucuna pruriens (a natural levodopa source) without amounts. A 67-day money-back guarantee is advertised (terms not confirmed).
GenF20 Plus is our top pick among HGH-releaser supplements because it's one of the few products in this category tested in a published trial, with published tablet amounts and written guarantee terms. If you try it, buy from the official site so the 67-day money-back guarantee applies, and keep expectations modest.
GenF20 Plus is our top pick among HGH-releaser supplements and our pick in this comparison: unlike HyperGH 14x, it has been tested in a published placebo-controlled trial, although that trial's main IGF-1 result wasn't statistically significant. HyperGH 14x is best for people who train and lists higher amino acid doses, but it has no published trial.
Both are Leading Edge Health tablet-plus-spray products with similar amino acids, herbs and animal-derived ingredients. GenF20 Plus lists lower doses and has one published trial. HyperGH 14x lists higher daily doses, is marketed to people who train, has no published trial, and its spray contains Mucuna pruriens, a natural source of levodopa.
We don't recommend it. The formulas overlap heavily (arginine, GABA, chromium, deer antler velvet), so combining them mainly stacks the same ingredients and their interaction risks. Talk to a healthcare professional first.
Buy GenF20 Plus from the official website. Its 67-day guarantee requires the empty boxes (plus any unopened ones) to arrive back within 67 days of delivery, shipping isn't refunded, and marketplace purchases generally aren't covered.
Both are dietary supplements, not medicines, and neither contains growth hormone. For both: L-arginine and GABA may lower blood pressure, arginine and chromium can affect blood sugar, and deer antler velvet may contain IGF-1, which is banned in tested sport. Avoid them in pregnancy or breastfeeding, or with a history of cancer unless your oncologist agrees. HyperGH 14x's spray also contains levodopa-containing Mucuna, so check with a doctor if you take Parkinson's drugs, MAO inhibitors, antidepressants or antipsychotics.
