A 7-amino-acid synthetic peptide derived from the ACTH(4-10) fragment with a C-terminal Pro-Gly-Pro for enzymatic stability.
Everything researchers usually message us about, answered on the page.
Yes, every batch. Every product we supply is independently HPLC-verified by Janoshik Analytical, a Czech specialist peptide-analysis laboratory unaffiliated with us. Reported purity is consistently above 99%.
Where a Janoshik report has been issued for the current batch, the printed Certificate of Analysis is supplied with the order. Otherwise, the verification record is published on our Purity page.
Every COA carries a unique verification key you can authenticate against Janoshik’s own portal at janoshik.com – so you don’t have to take our word for it. We’re the only UK supplier writing publicly about how to read these reports: how to read a Janoshik HPLC report. ›
Use the reconstitution card on the inside of the box lid as your reference next time.
One pen lasts the number of doses shown in the protocol cards above for your selected size. When it’s empty, drop a refill cartridge into the same pen body – the price for your size is in the calculator at the top.
Research use only. Procedure drawn from published cohort protocols. We do not provide medical or human-use guidance.
Lyophilised vial: stable 24+ months at 2–8°C, sealed and protected from light. Don’t freeze.
Reconstituted (after BAC water): ~30 days at 2–8°C. Don’t shake. Keep in the original glass vial. Discard if cloudy or discoloured.
BAC water bottle: 30 days once opened, refrigerated.
Published research literature on Semax uses subcutaneous administration in the abdomen, thigh or upper arm in human pharmacokinetic and phase 2 / 3 studies. Researchers rotate sites between administrations to reduce local tissue stress.

What should my dose be?
The clean answer: follow the protocol cards above. Published research literature on Semax uses titration – start low, step up at fixed weekly intervals. The phase highlighted in green is where most published research cohorts settle for ongoing study.
If you’re new to this compound, start at Phase 1 (the lowest dose shown above) for the full duration of that phase, then step up to the next. The titration is what limits the GI side effects reported in the trial – don’t skip it.
If you’ve used this compound before, you already know which phase you’re at. Tap the phase tabs above to see exactly what your dose costs at your selected vial or pen size, plus how long it will last.
If your protocol is non-standard: WhatsApp us before you order. We help researchers work out custom schedules every day and will tell you which size makes most sense for the cadence you’re running. Real human reply, not a chatbot.

Semax is a synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-7) with a C-terminal Pro-Gly-Pro extension. Characterised in preclinical literature for its stability profile and effects on BDNF expression in rodent models. Supplied as lyophilised powder for in-vitro research use only.
The above describes how this compound is characterised in the published peer-reviewed literature. It is not a claim about effects in humans.
Semax is supplied as a lyophilised (freeze-dried) powder in a sealed glass vial. For laboratory reconstitution, add the desired volume of diluent (typically bacteriostatic water) slowly down the side wall of the vial. Swirl gently until fully dissolved – do not vortex or shake. Store reconstituted solutions at 2–8 °C and use within 4–6 weeks.
Use our Reconstitution Volume Calculator to compute the resulting mg/ml concentration.
| State | Temperature | Shelf life |
|---|---|---|
| Lyophilised | 2–8 °C or -20 °C | Up to 24 months |
| Reconstituted | 2–8 °C | 4–6 weeks typical |
