02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Semax1 part · 7 residues
Each component is built from its own sequence with ideal bond lengths and angles, so every connection is exact. They are separate molecules in the vial, not bonded to each other; the stack is for viewing only. Poses are idealised, not measured conformations. Each component is confirmed separately on the lot certificate.
Structure viewer04In the lab
Selank and Semax are each studied on their own pathways in laboratory research. This blend combines them in one vial; the map shows the best-characterized pathway reported for each.
Blend
Selank / SemaxBlend of Selank and SemaxEnzyme inhibition
Endpoint studied
Inhibited enkephalin-degrading serum enzymes (IC50 20 µM), more strongly than puromycin or bacitracin.
Kost 2001 · PMID 11443939Specific binding
Endpoint studied
Labeled Semax bound specifically and reversibly (KD 2.4 nM); BDNF protein rose in basal forebrain at 3 h.
Dolotov 2006 · PMID 16635254Pathways as reported in the cited laboratory studies, for each compound in the blend. For in-vitro research use only.
05Research history
5 milestones, each linked to its PubMed record
Semax · Biochemical and Biophysical Research Communications
Serum breakdown of ACTH(4-10) and Semax is mapped; aminopeptidases trim both, but Semax is more stable against the other enzymes.
PubMed · PMID 1851003Selank · Bioorganicheskaia Khimiia
Selank and Semax inhibit enkephalin-degrading enzymes in human serum; pentapeptide fragments act too, shorter fragments do not.
PubMed · PMID 11443939Semax · Neuroscience Letters
In basal forebrain glial cultures, BDNF mRNA rose eight-fold and NGF mRNA five-fold 30 minutes after Semax.
PubMed · PMID 11457573Selank · Regulatory Peptides
Expression of 34 of 84 inflammation-related genes shifts in spleen tissue, with Bcl6 changing under Selank and its fragments.
PubMed · PMID 21609736Selank · Frontiers in Pharmacology
In frontal cortex, 45 of 84 neurotransmission genes changed 1 hour after Selank, correlating with changes seen after GABA.

The current released lot, SA-SEL-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
