In briefChecked October 2026
They aren't truly competing products. GenF20 Plus pairs amino acid tablets with an oral spray as an "HGH releaser", and it's our top pick among HGH-releaser supplements. GenF20 Calcium is a calcium supplement under the same brand name that comes free with larger GenF20 Plus orders, and we couldn't verify its form or amounts. The one small GenF20 Plus trial found that its main IGF-1 result was not significant compared with placebo.
⚡ The short verdict
Our top pick among HGH-releaser supplements is GenF20 Plus. GenF20 Calcium is worth it only for someone who needs more calcium, and a basic calcium-plus-vitamin-D product from a pharmacy does the same job. The full side-by-side breakdown follows below.
A calcium supplement carrying the GenF20 name, which is also given as a bonus with larger GenF20 Plus orders. We haven't verified its formula or amounts.

Neither product is a medicine. Both are over-the-counter dietary supplements, and they aren't intended to diagnose, treat, cure or prevent any disease. With GenF20 Calcium, the calcium can reduce absorption of thyroid medicine, bisphosphonates and some antibiotics. With GenF20 Plus, L-arginine and GABA may lower blood pressure, animal-derived ingredients are included, and anyone with a history of cancer should avoid it unless their oncologist agrees. Before you start any supplement, talk to a qualified healthcare professional, above all if you take prescription medication or have a health condition.
