What is Selank + Semax?
This blend pairs Selank, a tuftsin analogue, with Semax, an ACTH (4-10) analogue, co-lyophilized in one lot-matched vial. The two are frequently studied together because they act on different systems within the same broad research area. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.
What is Selank + Semax studied for?
- Combined nootropic pathway studies
- BDNF expression assays
- Anxiolytic and neuroimmune signalling research
- Combination versus single-compound comparisons
All applications above are in-vitro or preclinical research contexts. Selank + Semax is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot SEMSEL5-0803 show?
Every lot of Selank + Semax is tested by an independent US laboratory before it is listed. The report for lot SEMSEL5-0803 is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot SEMSEL5-0803 result |
|---|---|---|
| Identity | LC-MS/MS | Semax/Selank · conforms |
| Content | HPLC quantitation | 5.15, 5.37 mg |
| Purity | RP-HPLC (214 nm) | 99.76% |
| Endotoxin | USP <85> | <0.05 EU/mL |
| Heavy metals | USP <232> | <0.01 ppm |
How is Selank + Semax handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
Frequently asked questions
Why are these two paired?
They are studied together often enough that one vial saves a reconstitution; their mechanisms are distinct, which is the point of the comparison.
Can I get them separately?
Yes, both are sold as single compounds in this catalogue.
Is Selank + Semax for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
