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.
