N-Acetyl Semax

Minimum order 2 vials or 2 pens — delivery in 2 weeks
In a rat model of chronic stress, Semax (the N-acetyl form is a stabilised version of it) limited anhedonia and the drop in BDNF in the hippocampus.

Category VII — Mind & Sleep 🧮 Reconstitution calculator €31 – €45 from €24.80 to €36

In a rat model of chronic stress, Semax limited anhedonia 1.

It also limited the drop in BDNF in the hippocampus — a marker of neuroplasticity.

The N-acetyl form is a stabilised version of the same molecule, not a different substance.

No percentage in this study; the description is functional, in an animal model.

What we don't know: whether the same holds for human stress. Research use, pure.

Chronic stress in rats, Semax in, anhedonia limited, hippocampal BDNF more stable 1.

N-acetyl form = stabilised version of the same peptide. Same target, better stability.

No number here — functional protection in an animal model, nothing more.

Humans? We don't know yet. Don't make a leap the study doesn't support.

Everything we sell is for research. Clean batch, nothing inflated.

Rats under chronic stress, and Semax stepped in — anhedonia was limited 1!

And BDNF, the “guardian” of neuroplasticity in the hippocampus, didn't fall as sharply.

The N-acetyl form is simply a more stable version — same molecule, longer shelf life, not a new action.

We don't have a percentage — but we do have a clear, documented direction in an animal stress model 1.

The purity of the preparation that reaches you? There we are, as always, non-negotiable.

What we don't know yet: whether the human mind responds the same way. Research use — honestly, not promises.
