Russian Nootropic Stack
Stack of Russian nootropic/bioregulator peptides studied for cognitive and neuroprotective research.
This is a combination sold as one vial. It has not been studied as a single substance, so what is known is what is known about each part. Sources that report a dose for the blend report it for that mixture, not for any component on its own.
We have not published an audit on Russian Nootropic Stack. Everything below is reference material, not our own reading of the literature, treat it as a starting point for questions, not as a grade.
How it is thought to work
Combines nootropic/bioregulator peptides; components and mechanism per source.
Semax boosts brain growth factors and dopamine to sharpen focus and protect neurons, while Selank calms the nervous system via GABA to prevent overstimulation and anxiety, so together they aim to produce sharp attention without jitteriness or crashes.
Reported side effects
The most commonly reported side effect is headache (preventable with adequate hydration), and Semax can cause overstimulation or sleep disruption if dosed too late in the day.
Who should avoid it
People taking stimulants or MAO inhibitors should avoid or use extreme caution with this stack due to potentially dangerous interactions with Semax's dopamine-boosting effects.
What gets monitored
At-home blood test (SiPhox Health At-Home Blood Test) is listed as a supply item, but no specific labs or monitoring parameters are named on the page. [Source: peptidedosingprotocols.com]

These are figures published elsewhere, reproduced with their source. Peppersite does not recommend an amount for Russian Nootropic Stack or for anything else, and nothing below has been checked against the study it came from.
| Amount | Frequency | Route | Reported by |
|---|---|---|---|
| Semax: 300-800 mcg/day (SubQ), 400-600 mcg/day (intranasal); Selank: 250-500 mcg/day (SubQ), 400-750 mcg/day (intranasal). Maintenance example: Semax 600 mcg + Selank 400 mcg daily. | Once daily (SubQ, morning before 2 PM); 2x daily for Semax intranasal (AM + early afternoon); 2-3x daily for Selank intranasalStandard cycle: 4 weeks on / 4 weeks off; Short intensive: 10-14 days on / 10-14 days off; Extended: 8 weeks (5 days/week) / 4 weeks off; Clinical intranasal reference: 14-21 days on / 14-21 days off | Subcutaneous injection or intranasal (drops/spray) | peptidedosingprotocols.comWhat it saysHide(secondary reference; provider confirmation required).

- Each compound is reconstituted separately using bacteriostatic water (BAC water). For a 10 mg vial: add 3.0 mL BAC water to reach 3,333 mcg/mL, or 2.0 mL to reach 5,000 mcg/mL. For a 5 mg vial: add 2.0 mL BAC water to reach 2,500 mcg/mL, or 1.0 mL to reach 5,000 mcg/mL. Use 0.3 mL / 30-unit insulin syringes for accuracy at small volumes. Label each vial with compound name, concentration, and reconstitution date. Semax is light-sensitive (contains methionine, which oxidizes when exposed to light); wrap the reconstituted vial in aluminum foil or store in a dark container. Both vials are stable for approximately 30 days at 2-8 °C once reconstituted.
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.
Check 10 mg in 3 mL in the calculator →Can I stack Semax with Selank and BPC-157?
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.
