These dissolving strips carry two well-studied research heptapeptides in a pre-dosed thin film instead of a vial of lyophilised powder. A pack holds 20 separate strips. Each is a water-soluble polymer sheet with a set peptide load dispersed through it, so you can build a study arm by counting strips rather than weighing powder, calculating a dilution and sterile-filtering a solution.
The two active ingredients are Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro; CAS 129954-34-3) and Semax (Met-Glu-His-Phe-Pro-Gly-Pro; CAS 80714-61-0). Both are short lab-made peptides created by taking a natural active fragment — tuftsin in the case of Selank, ACTH(4–10) in the case of Semax — and adding a Pro-Gly-Pro tail that protects the end from exopeptidases. Both also dissolve freely in water, which is why they suit a dissolving film: the strip breaks up in watery media and releases its load without any organic solvent.
Researchers are interested in the pair because their bodies of evidence complement each other. Semax dominates studies of BDNF and NGF levels, TrkB signalling and tests of attention and memory; Selank dominates studies of GABA-A receptor subunits, enzymes that break down enkephalins, and genes switched on by stress. The film is mainly of interest as a way to compare handling and formats, not for any biological effect of its own.

Questions about Selank + Semax Dissolving Strips
How many strips does a pack hold?
Twenty single thin-film strips, each loaded with a fixed, pre-measured amount of Selank and Semax. As the dose per strip is set during manufacture, study arms are put together by counting strips, not by weighing powder and working out dilutions.
Are both peptides independently tested, with a COA?
Yes. An outside laboratory analyses the Selank and the Semax raw materials by HPLC to ≥99% purity and confirms their identity by mass spectrometry; the Certificate of Analysis for the batch is available. Check the pack's lot number against the COA before you log any data.
Must the strips be reconstituted?
No — that is the whole idea. The film dissolves straight into aqueous media: no weighing, solvent, mixing, filtering or bacteriostatic water, and the sealed pack needs no cold chain either.
What storage do the strips need?
Keep them sealed, cool and dry, away from light and damp. Moisture is what damages a thin film — once exposed, strips become sticky and hard to handle. Take them out singly using dry gloves or tweezers, and close the pack again straight away.
What is the logic of combining Selank and Semax?
Their research areas complement each other — Semax is linked to studies of BDNF, neurotrophins and attention, Selank to GABA and stress-response research — and both are small peptides that dissolve well in water and carry the stabilising Pro-Gly-Pro end, so they load easily into a film.
