Semax + Selank Blend Price Report
How this report is calculated
The headline and median use each vendor's lowest whole-package checkout cost to obtain at least 10mg. Smaller packages are multiplied until the target is met, while larger packages retain their full checkout price. The lowest package total is shown only as secondary context because package sizes differ. Known public coupon discounts are applied. Shipping, tax, and unverified promotions are excluded. COA coverage counts vendors with an exact compound-and-strength match in the listing-evidence projection; report dates and lot identifiers remain specific to each certificate.

What is Semax + Selank Blend? Research, safety, and status
Semax is a synthetic seven-amino-acid peptide developed in Russia for neuroprotection and cognitive enhancement. It is derived from a fragment of adrenocorticotropic hormone (ACTH) but, by design, carries none of ACTH's hormonal effects, its activity is restricted to neurotrophic, neuroprotective, and immunomodulatory pathways.
It is one of the more scientifically substantiated peptides in the nootropic space, with a research record spanning genome-wide transcriptomics, proteomics, rodent behavioral models, and human clinical trials in stroke and cognitive disorders. It has been an approved prescription pharmaceutical in Russia for decades and was added to the Russian List of Vital and Essential Drugs in 2011.
Key takeaways
- Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro, MW ≈ 813.9 g/mol) built from the ACTH(4-7) fragment plus a stabilizing Pro-Gly-Pro tail, developed in 1982 in Russia for neuroprotection and cognitive enhancement.
- Despite its ACTH origin it is devoid of hormonal activity, it does not raise cortisol or engage the HPA axis; its action is confined to neurotrophic, neuroprotective, and immunomodulatory pathways.
- Its best-documented mechanism is potent upregulation of BDNF and NGF via the CREB→TrkB pathway, alongside dopaminergic/serotonergic modulation (sensitization rather than direct flooding) and transcriptomic-level suppression of neuroinflammation after ischemia.
