MEHFPGPSemax research guide
Plain-language notes on Semax sequence identity, ACTH-fragment literature, BDNF/TrkB marker papers, enzyme records, and lab-only handling boundaries.
01 - Short version
The quick read.
Plain-language context only. No preparation steps, no use instructions, and no product-effect claims.
New to Semax? Here's the short version. Semax is a synthetic heptapeptide commonly written as MEHFPGP.
This guide keeps ACTH-fragment, enzyme, monoamine, and BDNF/TrkB marker context separate from Form Laboratories product claims.
Lot identity, purity, appearance, and supplied form remain COA-led. Published papers are used only as scientific background.

Identity information lets you compare the guide with the product label. It is not a certificate, mixing method, or instruction for use.
03 - What studies look at
The main research themes.
Each note stays at study-context level and avoids use instructions.
01ACTH-fragment degradation recordPotaman et al., Biochem Biophys Res Commun, 1991.
The paper supports structure and enzyme-stability context.
02BDNF / TrkB expression paperDolotov et al., Brain Res, 2006.
The paper is the clearest neurotrophin marker anchor in this guide.
03Peptide-development reviewDeigin et al., Pharmaceutics, 2022.
The review provides broad background without replacing primary identity records.
Storage, appearance, purity, and release state come from the matching lot record.
Use the product label and matching COA as the authority for storage, appearance, purity, and release state.
This guide is educational context only. It does not include preparation, administration, human-use, or veterinary-use directions.
For laboratory research use only. 18+ only. Not for human consumption or veterinary use.
05 - FAQ
Common questions.
What is SEMAX supplied for?
SEMAX is supplied as laboratory research material only. It is 18+ only, not for human consumption, and not for veterinary use.
Does this page include matching COA information?
Yes. The product page lists lot, identity, purity, appearance, release status, and storage notes for SEMAX.
How should the vial be handled after delivery?
Follow the label and matching COA paperwork. This page repeats 2-8 C storage guidance and light-protection notes before checkout.
What sequence identifies Semax?
The catalogue uses the seven-amino-acid sequence MEHFPGP, written in full as Met-Glu-His-Phe-Pro-Gly-Pro.
What does BDNF/TrkB mean here?
BDNF is brain-derived neurotrophic factor, and TrkB is a receptor name used in the cited marker literature. The page uses them as research markers only.
Can this be used outside a lab?
No. Semax from Form Laboratories is for laboratory research only, 18+ only, and not for human consumption.
