Semax + Selank Blend peptide: Stacks research guide

In short: Semax and Selank in one vial at a fixed 1:1 ratio, in two strengths: 5 mg + 5 mg and 10 mg + 10 mg per vial. Two heptapeptides developed at the same Moscow institute. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.

Not medical advice. Semax + Selank Blend is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.

What Semax + Selank Blend is

A fixed 1:1 research blend of Semax and Selank, offered at 5 mg + 5 mg and 10 mg + 10 mg per vial: two short synthetic neuropeptides from the same research group in one vial.

One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

Semax and Selank in one vial at a fixed 1:1 ratio, in two strengths: 5 mg + 5 mg and 10 mg + 10 mg per vial. Two heptapeptides developed at the same Moscow institute.

Research contexts

Peer-reviewed papers discuss Semax + Selank Blend in specific lab settings. The points below reflect research questions, not health claims.

Research vs. personal use: Literature describes experiments in cells and animals. That is distinct from real-world use. Our products are for laboratory research only.

Typical study contexts

Component peptides are usually characterised individually first; combination papers are less common.

Two neuropeptide research compounds pre-combined at a fixed 1:1 ratio.

Two vial strengths in one product: 5 + 5 mg and 10 + 10 mg.

Semax: ACTH(4-10) analogue studied for BDNF/TrkB and monoamine signalling in rodents.

Selank: tuftsin-derived heptapeptide studied for gene-expression effects in rat frontal cortex.

Why Stacks research matters

Stack products combine research peptides. Guides note how components are usually studied alone first.

Mechanisms (technical review)

Our datasheet lists mechanistic themes from preclinical work. These are research endpoints, not health claims.

Two neuropeptide research compounds pre-combined at a fixed 1:1 ratio

Two vial strengths in one product: 5 + 5 mg and 10 + 10 mg

Semax: ACTH(4-10) analogue studied for BDNF/TrkB and monoamine signalling in rodents

Selank: tuftsin-derived heptapeptide studied for gene-expression effects in rat frontal cortex

Both heptapeptides share a C-terminal Pro-Gly-Pro extension

Both compounds are also sold on their own, so the blend can be benchmarked against its parts

Lab handling & preparation

Storage: Lyophilised powder: store in freezer (−20 °C). Reconstituted: refrigerate 1–6 °C, away from sunlight. Use within the validated stability window for the specific batch and formulation.. See the storage guide.

Published pharmacokinetic context: Laboratory research material. No amount, schedule or administration guidance is published or recommended on this page.

Purity check: Use the COA reading guide and the published Certificates of Analysis (no current certificate is listed for Semax + Selank Blend yet).

Common Questions People Are Asking

What is in the Semax + Selank Blend?

Each vial holds Semax and Selank in a fixed 1:1 ratio: 5 mg of each (10 mg per vial) or 10 mg of each (20 mg per vial). Choose the strength from the pack-size menu.

Why are Semax and Selank sold together?

They are structurally related heptapeptides from the same research institute and are often discussed together. This page cites no study of the pair or of the fixed blend; the evidence listed concerns each peptide separately.

What does the research on each show?

In rats, a single Semax application raised hippocampal BDNF and TrkB, and in rodents it raised a striatal serotonin metabolite. Selank changed the expression of many neurotransmission-related genes in rat frontal cortex. All of it is preclinical and from one research group and its collaborators.

Is there a Certificate of Analysis for this blend?

Not yet. No independent analytical report has been published for this material, so no purity figure is quoted. If one is published it will appear on this page and on our COA page.

Is there human data on this blend?

No study of the blend is cited, and no human study of either peptide is cited on this page. This is laboratory research material, sold strictly for in-vitro and preclinical research and not for human or veterinary use.

Is this page medical advice? Can I use Semax + Selank Blend for my health?

No, and no. This article is educational only. We do not provide dosing, medical recommendations, or health claims. Our products are sold strictly for laboratory research, not for personal use of any kind.

Where do I find Semax + Selank Blend specs, purity certificates and pricing?
