Selank vs Semax

Two signalling peptides compounds, compared by what each molecule is: class, length, mass, origin and what it binds, side by side. Nothing here compares what either one does.

Origin and target

Where each one comes from, and what it binds

Selank

Origin. A synthetic analog of tuftsin, a naturally occurring tetrapeptide, extended with a proline-glycine-proline tail.

Target. Built on the tuftsin sequence with the same C-terminal stabilizing extension used in Semax.

Semax

Origin. A synthetic analog of the ACTH(4-7) fragment, extended with a proline-glycine-proline tail.

Target. Derived from the adrenocorticotropic hormone sequence, modified for stability against enzymatic cleavage.

Handling

The same for both

Both ship as freeze-dried powder, both mix with bacteriostatic water the same way, and both are stored at minus 20 C out of the light until then. What differs is which breakdown route each sequence is prone to, and the stability guide shows how to read that from the amino acids.
