Description
The Selank / Semax Research Set pairs the two Pro-Gly-Pro heptapeptides in one order: one sealed vial of Selank 10 mg and one sealed vial of Semax 10 mg. These are the same vials sold individually in the Attestryn catalog, supplied as lyophilized solids, and the set is priced below buying both separately.
What is in the Selank / Semax research set
| Compound | Amount | CAS number | Molecular formula | Molecular weight |
|---|---|---|---|---|
| Selank | 10 mg | 129954-34-3 | C33H57N11O9 | ≈751.9 g/mol |
| Semax | 10 mg | 80714-61-0 | C37H51N9O10S | ≈813.9 g/mol |
About the compounds
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) built on the tuftsin sequence with a Pro-Gly-Pro extension.
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) built on the ACTH (4-7) fragment with a Pro-Gly-Pro extension.
Why researchers order the Selank / Semax set
- Set pricing: the set costs less than buying the same vials separately. The amount you save is shown next to the price.
- Related structures: both compounds are synthetic heptapeptides that end in the same Pro-Gly-Pro sequence, which makes them a natural pair for comparative work.
- Third-party tested: every lot of every vial in the set is tested by an independent laboratory before it is released for sale.
- Sealed and lyophilized: each compound ships as a stable solid in its own crimp-sealed glass vial. Store as directed on the vial label and protect from light.
- Fast US shipping: orders received by 3:30 PM ET on business days begin processing the same day and ship by USPS with tracking. Orders of $199 or more ship free.
Selank / Semax research set FAQ
Are the vials in the set the same as the individual products?
Yes. The set contains the same sealed vials sold individually as Selank 10 mg and Semax 10 mg.
How do Selank and Semax differ?
Both are seven amino acids long and share a C-terminal Pro-Gly-Pro extension. Selank is built on the tuftsin sequence (Thr-Lys-Pro-Arg), while Semax is built on the ACTH (4-7) fragment (Met-Glu-His-Phe).
Does volume pricing apply to research sets?
No. Research sets already carry set pricing, so the automatic volume discounts (5% off 3 or more, 10% off 5 or more of the same item) apply to single peptides and blends.
Is this set for human or veterinary use?
No. All Attestryn products are sold for laboratory research use only. They are not drugs, foods, cosmetics or dietary supplements, and they are not for human or veterinary use.
For laboratory research use only. Not for human or veterinary use. Not a drug, food, cosmetic or dietary supplement. Attestryn does not provide dosing, reconstitution or administration information. Purchasers confirm they are qualified researchers aged 21 or older.
