Selank in the Philippines
Selank is a synthetic heptapeptide built from tuftsin, an immunomodulatory fragment of immunoglobulin G, extended with the same Pro-Gly-Pro tail used in Semax. The extension is what gives it a usable half-life; tuftsin alone degrades too quickly to study.
Research attention sits on GABAergic modulation and on the stress response, with the recurring observation in the literature being anxiolytic signalling that does not carry the sedation associated with benzodiazepine-class compounds. That distinction is the reason most of the published work exists.
Selank ships as a 10mg vial of powder. The storage rule is simple: cold, dark and sealed, between 2 and 8°C, and back in the fridge once mixed. To place an order, tap the WhatsApp button; the message is ready to send, and we answer with availability and a delivery slot. Outside the metro, parcels reach 1 to 2 days Luzon, 2 to 3 Visayas, 3 to 5 Mindanao. For the research background, including how it differs from Semax, read the Selank guide.

Handling and storage
Sealed vials
Store sealed lyophilised vials refrigerated at 2 to 8 °C, away from light.
Primara Labs storage instructionAdding diluent
Add the diluent slowly down the inside wall of the vial rather than straight onto the powder.
Mixing
The US prescribing instructions for tesamorelin, a lyophilised peptide medicine, tell users to swirl the vial to mix the powder and liquid, and not to shake it.
Tesamorelin US instructions for use, DailyMed · checked 23 September 2026Appearance
The same instructions say not to use the solution if it is cloudy, discoloured or has particles in it.

CDC guidance, citing USP chapter 797, is that a multi-dose vial once opened is dated and discarded within 28 days unless the manufacturer states another date, and never used past its original expiry.

How it works
Selank is a synthetic seven-amino-acid peptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro). Laboratory and rat studies propose two mechanisms, allosteric modulation of GABA receptors and inhibition of the enzymes that break down enkephalins. Neither has been confirmed in human pharmacology studies.
Targets: Proposed GABA receptor modulation and enkephalinase inhibition (laboratory work)
What the research shows
Selank is a synthetic heptapeptide studied in Russia for anxiety disorders. Its human evidence is small comparative studies against benzodiazepines without a placebo arm or stated random allocation. Its proposed mechanisms, GABA receptor modulation and enkephalinase inhibition, come from laboratory work.
