Published research context (not product claims)
Semax is a synthetic ACTH(4–10) analogue with a Pro-Gly-Pro C-terminus from Russian peptide programmes. Papers describe cell and receptor-assay models.
Selank is a synthetic tuftsin analogue with the same Pro-Gly-Pro tail. Papers describe GABA-related and immune-assay models.
A separate body of local clinical literature exists for authorised Semax or Selank products in some countries. Those authorisations do not apply to this research blend and do not make it a UK medicine.
Shop marketing that pairs the two as a “nootropic stack” is not a claim for this listing. There is no MHRA marketing authorisation.
