Selank and Semax hold genuine regulatory approvals — in Russia, based on domestic clinical programs largely unavailable in translated, peer-reviewed form. That asymmetry defines how they should be evaluated: not as unknown compounds, but as compounds whose evidence cannot be independently audited.
Both are also stability-fragile in ways the gray market routinely ignores; Semax in particular requires cold-chain handling that our shipping-condition testing suggests is rarely maintained.
