Semax 11mg Research Peptide Vial

Semax 11mg: An ACTH Derived Heptapeptide

Semax is a synthetic peptide. Seven amino acids total. It comes from a small piece of ACTH, a hormone tied to stress response. Scientists in Russia built it back in the 1980s. They added a Pro-Gly-Pro tail at the end. That tail helps it resist breaking down too fast.

Quick Facts

Name: Semax
Sequence: Met-Glu-His-Phe-Pro-Gly-Pro
Formula: C38H54N12O9
Weight: around 826.92 g/mol, as the acetate salt
CAS number: 80714-61-0
Look: White to off white powder, freeze dried

What Makes It Different

The native ACTH fragment barely survives in plasma. Just a few seconds. Semax's added tail changes that. It blocks certain enzymes from breaking the peptide down too quick. That's the main reason researchers reach for Semax over the unmodified ACTH piece.

What Labs Study It For

Researchers use Semax to look at:

BDNF gene expression
Neuroprotective signaling, in animal models
Cognitive and learning pathways
Oxidative stress regulation
Structure activity work tied to ACTH fragments

Some labs also pair Semax with Epithalon, especially when comparing different short regulatory peptides side by side.

Regulatory Status

The FDA hasn't approved Semax for treating anything. It's sold strictly as a research compound.

Legal and Safety Info

Not a supplement, just a raw research compound. Keep away from kids. Long term safety data is limited, so only trained lab personnel should handle this.

Buying this means agreeing to use it legally, for research only.
