Common questions
What is the Russian Nootropic Stack?
It is a two-peptide research protocol combining Semax (a cognitive activator that boosts BDNF and dopamine) and Selank (an anxiolytic peptide that enhances GABA signaling). Both compounds were developed at the same Russian research institute and are approved pharmaceuticals in Russia. The stack targets 'calm focus' — sharper thinking without the jittery edge that can come with single-compound nootropics or stimulants.
Can I stack Semax and Selank?
Yes — they're designed to be complementary. Semax handles the cognitive activation side (BDNF, dopamine, focus). Selank handles the calming side (GABA, serotonin, anxiety reduction). They work on different but overlapping pathways. Russian clinicians have prescribed them together for years. Just don't start both compounds on the same day — run Selank alone for 5–7 days first to confirm tolerance, then add Semax.
How do you dose Selank and Semax with injection?
For subQ, start Selank at 250 mcg/day for the first week, then add Semax at 300 mcg/day in Week 2. Titrate each independently over Weeks 3–8: Selank to 400–500 mcg/day, Semax to 500–800 mcg/day. Both go once daily in the morning, at separate injection sites, using separate syringes. All Semax doses must be before 2 PM to avoid sleep disruption.
Why Semax first then Selank 45 minutes later — and does that apply to subQ?
The intranasal order is usually Selank first, then Semax 15–30 minutes later (not 45). Both compounds use the same nasal absorption pathway, so spacing them out prevents displacement. For subQ injection, no gap is required — both can be injected within a minute of each other at different sites. The 'wait' rule is specifically a nasal-absorption rule, not a peptide-interaction rule.
How many units a week should I take of a Semax & Selank blend?
At a 3,333 mcg/mL reconstitution (10 mg vial + 3 mL BAC water), a typical maintenance dose is 18 units of Semax (600 mcg) + 12 units of Selank (400 mcg) per day = ~30 units total per day. Over a 5-day week (5-on/2-off pattern), that's 150 units total across both compounds. For pre-blended vials, always check the actual mg breakdown on the vial label and calculate from there.

Yes — this is a known three-compound pattern. BPC-157 adds gut-brain axis support for users whose anxiety or cognitive symptoms have a digestive component. BPC-157 also has its own anxiolytic activity in animal models. Typical dosing: 250–500 mcg/day of BPC-157 in addition to your standard Semax + Selank protocol. This is more complex (3 injections per day) and gives up some clarity on which compound is causing which effect.
Should I use intranasal or subcutaneous injection for this stack?
Both work. Subcutaneous gives more consistent absorption and easier once-daily simplicity but requires injections. Intranasal is the original Russian-approved route — no needles, but absorption is variable and you need 2–3 administrations per day. Don't switch routes mid-cycle — subQ doses are usually too low for nasal use, and nasal doses can be too high if pushed through subQ.
How long should I run this stack?
Standard cycle is 4–8 weeks on, 4 weeks off. Shorter 10–14 day intensive courses are used for acute cognitive demands (exam prep, project deadlines). An alternative 5-day-on / 2-day-off schedule extends to 8 weeks with built-in micro-breaks. Neither compound builds tolerance or dependence in published trials, so cycling is more about avoiding receptor adaptation than withdrawal protection.
