Every lot of Selank / Semax is tested by an independent ISO/IEC 17025-accredited lab in the USA. 99%+ purity isn't a target here. It's the requirement.
Don't take our word for it: test any vial at an accredited lab of your choice. If HPLC purity comes back under 99%, we refund your order and pay for the test.
This is a blend. Selank and Semax are combined in a single vial in equal parts. Selank is a tuftsin-derived peptide studied for anxiolytic-like endpoints and GABAergic signalling; Semax is an ACTH(4-10) analog studied for BDNF expression and neuroprotection. Both originate from the same research lineage and are frequently studied together, though the combination is not characterised as a single formulation.

Anxiolytic-Like Signalling
Selank
Selank is a synthetic analog of the immunomodulatory peptide tuftsin. GABAergic signalling and anxiolytic-like endpoints are the characterised readouts in rodent models, alongside effects on enkephalin degradation.

BDNF Expression & Neuroprotection
Semax
Semax is an ACTH(4-10) analog without corticotropic activity. Elevated BDNF and NGF expression is measured in rodent hippocampus, and neuroprotective endpoints are characterised in ischaemia models.

FAQ
Common questions about Selank / Semax
Both are heptapeptides from the same research lineage and are frequently studied in parallel, Selank for anxiolytic-like endpoints and Semax for neurotrophic expression. One vial holds both under matched handling.
No. Each peptide is characterised separately and no interaction data exists for the pair.
Two: 5 mg of each peptide, and 10 mg of each. The ratio is equal parts in both.
Each lot is analysed by reverse-phase HPLC and released at ≥99%, with a Certificate of Analysis.
Store lyophilized at -20°C for long-term stability, protected from light and moisture, and avoid repeated freeze-thaw cycles.
