About Semax

What it is
Semax is a synthetic heptapeptide analog of a fragment of the hormone ACTH, modified with a Pro-Gly-Pro tail to resist rapid enzymatic breakdown. In laboratory and animal studies it raises brain levels of BDNF and NGF and influences monoamine signaling, and it is mainly studied for stroke recovery, cognition, and neuroprotection. It is registered and used in Russia for ischemic conditions but is not FDA approved.
How it works
It acts as a stabilised ACTH(4-7) fragment analog that raises brain BDNF and NGF and modulates monoamine signaling.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
