What users report
Calm without drowsiness
Less fatigue, more clarity
Calm that lasts
Calm that does not make you sleepy: the mind settles, and the day goes on.
Calm without drowsiness
In a Russian trial in 62 adults, its calming effect matched that of a reference calming drug, with no sedation (Zozulya, 2008).
Less fatigue, more clarity
The same trial found a stimulating, anti-fatigue effect that the reference drug did not have.
Calm that lasts
In another Russian trial, the calming effect was still present after the last dose (Medvedev, 2014).
Effect still present about one week after the last dose, in that trial.
Laboratory research
Read more +Show less −
People choose it for calm without drowsiness, often felt the same day, according to users.
What it is: A 7-amino-acid peptide derived from tuftsin, a natural antibody fragment, developed by the Russian Academy of Sciences, that acts on the GABA system without sedation.
Laboratory research
Against a reference anti-anxiety drug, Selank achieved the same effect on anxiety, without sedation, plus an anti-fatigue effect (62-patient trial, 2008).
This 7-amino-acid peptide is derived from tuftsin, a natural antibody fragment. Developed by the Russian Academy of Sciences, it is approved in Russia as an anti-anxiety drug.
Why people choose it:
- Calm: users often report feeling calmer the same day; in the Russian trials, some patients responded by day 3.
- GABA system: one hour after a single administration, 45 of the 84 neurotransmission genes studied change expression (Frontiers in Pharmacology, 2016).
- Lasting effect: in 60 patients, the benefit was still present one week after stopping (2014).
- Stress: it slows the breakdown of enkephalins, peptides of the stress response.

What to combine it with?
Pick one to three products: the text follows your combination.
Alert calm, à la carte
What each one brings
- Semax : It raises BDNF: focus and memory.
- Selank : It acts on the GABA system without sedation: calm, without drowsiness.
Why together
Same Moscow institute, two roles: attention for Semax, calm for Selank. It is the pairing the community cites most, the alert-calm pairing, and Brain Blend combines it in a single pen.
What adds up
- Sharp attention without nervousness, the effect users look for when they combine the two.
- With two pens, each signal is adjusted separately; with one, Brain Blend gives the same pairing in one injection.
In practice
Two pens, two different injection sites, each on the protocol from its own page.
Also available in a single pen: Brain Blend
When will I feel the effects?
Week 1
The first week
Mild calm is often described within the first few days, sometimes with a passing headache; it becomes steadier by the end of the week.
Week 2
A steady response
Between the eighth and the fourteenth day, most people describe a steady response.
Week 3
Calm returns
Users describe a steadier everyday calm as the cycle goes on.
Week 4 and up
The end of the cycle
The 4-week cycle ends. The effect is often described as lasting about a week after stopping.
These timings vary from one person to the next. This timeline is a guide, not a promise.
