Selank + Semax Blend: What You Get in One Vial

The Selank + Semax Blend from Peptide God costs $59.95, $10.00 more than the vendor's semax-only solution, and it is the only way to get selank from the vendor we cover. That makes the selank semax blend the default product for anyone searching for selank in the US research market, whether they wanted a blend or not.

We look here at what is in the vial according to the listing, what the fixed ratio means, how the price compares and what the listing leaves out. Neither peptide in the blend is FDA-approved; it is sold for research use.

What the listing says is inside

According to the vendor, the vial holds two peptides in a ready solution: selank and semax, in a fixed ratio. The listing classes it as a "heptapeptide blend" with a research focus on "cognition and stress research".

Two things are missing from that table that a buyer might expect: the ratio itself and a purity percentage. We would ask the vendor for both, or for batch documentation, before ordering for any serious comparison work.

Why the two peptides are paired

Selank and semax are paired because they come from the same Russian research tradition and are studied for related themes. Selank, built on tuftsin, is researched mostly for anxiety. Semax, built on a fragment of ACTH, is researched mostly for cognition. The vendor's phrase "both anxiolytic and cognitive arms" refers to that split.

The pairing is a product decision, not an approved combination. No regulator has evaluated selank and semax together as a medicine, in the US, and the Russian registration covers selank on its own, not this blend. Our selank vs semax page compares the two molecules separately.

What a fixed ratio means for research

A fixed ratio means you cannot change how much selank you get relative to semax. The vendor lists it as a drawback, and we agree it is the main limitation of the selank semax blend.

• You cannot study selank alone with this product.
• Any result is a result for the combination, not for either peptide.
• To separate the effect of semax, you need the semax-only solution as a comparison.
• Because the ratio is not printed on the listing, two batches cannot be compared on that point without asking the vendor.

Blend vs semax alone: the price math

The blend costs $59.95 and the N-Acetyl Semax Amidate costs $49.95, so selank adds $10.00, about 20%, to the semax-only price. Both come from the same vendor with free US shipping over $100 and 30-day free returns.

The blend-plus-semax order is the one we would point most researchers to. It clears the shipping threshold and gives the only comparison these listings allow. More on the semax product on our semax page.

Regulatory status of each half

The two halves of the blend sit at different points in the US process, and neither is approved. Semax was recommended for the 503A bulks list by the FDA's advisory committee on 24 July 2026, 8 votes to 5, a non-binding step that still needs FDA rulemaking. Selank was not reviewed. Neither was named in the FDA's 24 August 2026 warning letters to five online vendors.

Those letters still matter for a blend sold as a solution. The FDA said it looks at whole websites, and treated dosing guidance and preparation tools as signs of human-use intent. That is why no responsible listing, and no page on this site, tells you how to use the blend. See selank FDA status for the timeline.

Who the blend suits and who it does not

The selank semax blend suits research that is about the combination itself. It does not suit research that needs selank on its own, because that product is not offered by our vendor.

It is sold for research use only and is not approved for human use in the US. If your interest is your own health, talk to your doctor before anything else.
