These aren’t really alternatives. GenF20 Plus is an amino acid tablet and oral spray “HGH releaser” and our top pick among HGH-releaser supplements. GenF20 Calcium is a calcium supplement sold under the same name and included free with larger GenF20 Plus orders; we couldn’t verify its form or amounts. GenF20 Plus has one small trial whose main IGF-1 result was not significant versus placebo.
⚡ Quick Verdict
GenF20 Plus is our top pick among HGH-releaser supplements. GenF20 Calcium only makes sense if you need extra calcium, and a basic pharmacy calcium-plus-vitamin-D product does the same job. 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.
