The basics

What is it?
HNG is Humanin with one amino acid swapped (serine 14 to glycine), which makes it more active in animal studies. It is a variant of Humanin — see the Humanin page for the natural form.

Official status: Not nominated for 503A compounding · Checked 2026-08-04

Can a doctor prescribe this?

Small pharmacy (503A)
Never put forward to FDA
Large outsourcing facility (503B)
Never put forward to FDA

Not FDA approved and not on the U.S. compounding list. A doctor cannot prescribe it.

503A is a pharmacy making a single prescription for one patient. 503B is a facility making batches. They are governed by separate lists. Where a category is shown, it is a position on the FDA's list of substances that have been put forward and are still being worked through — not the final list, which is set by rulemaking. Category 1 means the FDA does not plan to act against a pharmacy that makes it while the review runs.
