Frequently Asked Questions
What is the Selank + Semax blend?
The Selank + Semax 20mg blend is a pre-combined research formulation containing both Selank (a tuftsin-analogue neuropeptide) and Semax (an ACTH(4-10) analogue), allowing researchers to study both compounds’ complementary pathways in a single vial.
What purity is the Peptalix Labs Selank + Semax blend?
Independently tested at 99.75% purity by Freedom Diagnostics. Net content: Selank 11.72mg and Semax 12.86mg per vial, Lot 125-02-GGB, Accession #2605190099, reported 05/20/2026.
Why study Selank and Semax together?
Selank is studied for GABAergic and immune-modulating pathways, while Semax is studied for BDNF/NGF neurotrophic signalling. Researching them together allows comparison of complementary neuropeptide mechanisms within a single research protocol.
How is the Selank + Semax blend stored?
Store the sealed lyophilised vial at -20C. Once reconstituted with bacteriostatic water, store at 2-8C and use within 28 days. Do not freeze a reconstituted solution.
How do I reconstitute the Selank + Semax blend?
Draw the desired volume of sterile bacteriostatic water into a fresh syringe and inject slowly down the inner wall of the vial. Gently swirl until fully dissolved. Never shake.
Can I buy the Selank Semax blend online in the USA?
Yes. Peptalix Labs offers the Selank + Semax 20mg blend for purchase online for qualified USA researchers. COA-verified at 99.75% purity, GMP-sourced, same-day shipping.
Does Peptalix Labs ship the Selank Semax blend internationally?
Yes, to Canada, Australia, the United Kingdom and most of Europe, with tracked delivery in 5-12 business days.
Is the Selank + Semax blend the same as buying both separately?
The pre-combined blend contains both peptides reconstituted from a single vial in fixed proportions (Selank 11.72mg / Semax 12.86mg). Researchers wanting independent control over each compound’s ratio may prefer purchasing Selank and Semax separately.
What mass spectrometry confirms the blend’s identity?
Freedom Diagnostics confirms both Selank and Semax identity independently via LC-MS within the same chromatogram run, with separate purity values reported for each component.
Is this blend legal to purchase in the USA?
Yes, as a research chemical for qualified researchers conducting in-vitro laboratory studies. Not FDA-approved for human use. Sold strictly for research purposes.
What is the appearance of the Selank + Semax blend?
White lyophilised freeze-dried powder, as confirmed in the Freedom Diagnostics COA (Lot 125-02-GGB).
What is the typical research use case for this blend?
Researchers studying combined nootropic-peptide pathways — comparing GABAergic/immune modulation (Selank) against BDNF/neurotrophic signalling (Semax) — often use this blend to standardise dual-compound exposure within a single research model.
Which lab verified this blend’s purity?
Freedom Diagnostics, a US-based independent laboratory operated by Principal Chemist Alex Johnson. Accession #2605190099, reported 05/20/2026.
Can I buy Selank and Semax separately instead?
Yes. Peptalix Labs sells Selank 10mg and Semax 10mg as standalone products if you require independent dosing control rather than the fixed-ratio blend.
What other peptides pair well with this blend?
Researchers studying this blend often also investigate PE-22-28, Pinealon, and DSIP for broader cognitive and neuropeptide research panels.
