How we test

Simple terms

What Semax + Selank does in the body

Two Russian heptapeptides in one vial — an ACTH fragment analogue and a tuftsin analogue, each with its own paper trail.

Semax is ACTH(4–10) rewritten with a Pro-Gly-Pro tail, studied for BDNF and antioxidant enzyme transcription in nerve cells. Selank is tuftsin rewritten the same way, studied for GABA tone and how long enkephalins last. They share a tail and a country of origin, not a receptor. This blend is both named sequences, freeze-dried, for a bench that wants the pair. It is not a nootropic, not an anxiolytic, and not a medicine.

Two named heptapeptides: BDNF/TrkB neighbourhood (Semax) and GABA/enkephalin neighbourhood (Selank). A pair for a bench that wants both paper trails. Not a focus pill.

What the work looks at

  • BDNF and TrkB signalling in published Semax work
  • GABA and enkephalin tone in the Selank literature
  • Why an ACTH fragment and a tuftsin analogue are not one molecule
  • The Pro-Gly-Pro tail that stabilises both heptapeptides

Hypothetical research neighbourhood

  • Cognitive / BDNF models

    Semax literature on nerve-cell transcription. Hypothetical neighbourhood, not a nootropic claim.

  • Stress-tone / GABA models

    Selank literature. Not an anxiolytic medicine.

Drawn from published cell and animal work. Hypothetical research neighbourhood — not a diagnosis, not a medicine, not a protocol. This vial is labelled for research use only.

Hypothetical research reconstitution

How this vial is typically mixed

Hypothetical research reconstitution for the named catalogue vial. Not a protocol, not medical advice, not a use instruction. These amounts sit in published and commonly cited laboratory ranges. The vial is labelled for research use only — not for human or veterinary administration.

How often
Once or twice daily
10–14 days on, then a pause, in the original Russian notes

Bench steps

  1. Let the vial sit until it is no longer cold to the touch.
  2. Wipe the stopper with 70% isopropyl alcohol. Let it dry.
  3. Draw 2 ml bacteriostatic water (0.9% benzyl alcohol).
  4. Run the water slowly down the inside glass — do not blast the cake.
  5. Roll between finger and thumb until the cake is gone. Do not shake.
  6. Label the date. Store the solution at 2–8 °C. Do not freeze. Use within 30 days unless the note below says otherwise.

The literature on these two is often intranasal, not a drawn subcutaneous mark. Same water, same fridge. Short courses, not a forever molecule.

What this is

Buy Semax + Selank 20mg. Semax is the ACTH(4–10) analogue MEHFPGP; Selank is the tuftsin analogue TKPRPGP. Two named heptapeptides the nootropic and anxiolytic literatures actually write down, combined in one US-made research aliquot. HPLC-characterised. For laboratory research only — not a medicine.

Laboratory handling

Lyophilised solid. Keep refrigerated, dry and dark. Reconstitute under aseptic laboratory technique with bacteriostatic water. For in-vitro research only — not for human or veterinary use. Peptide orders over £75 include the sterile kit.

Journal

Focus, stress tone and the Semax / Selank pair

Semax is an ACTH fragment analogue studied for BDNF. Selank is a tuftsin analogue studied for GABA and enkephalin tone. They share a tail and a country, not a receptor. One vial, two paper trails — not a nootropic, not an anxiolytic.

About Semax + Selank

Why Semax and Selank in one vial?

They are two different heptapeptides. Semax is an ACTH(4–10) analogue (MEHFPGP); Selank is a tuftsin analogue (TKPRPGP). The literatures sit next to each other, not on top of each other. This 20mg listing is both named sequences, lyophilised together, so a bench that wants the pair does not order twice. Not a nootropic product and not a medicine.

What does Semax + Selank do in the body?

Two Russian heptapeptides in one vial — an ACTH fragment analogue and a tuftsin analogue, each with its own paper trail. In published cell and animal work — not a use instruction. Semax + Selank 20mg is labelled for research use only, not a medicine.

Is Semax + Selank for human use?

No. Semax + Selank 20mg is labelled FOR RESEARCH USE ONLY. NOT FOR HUMAN CONSUMPTION. It is a laboratory reagent, not a medicine, food or cosmetic.

What purity and identity do you publish for Semax + Selank?

≥98% HPLC. CAS 80714-61-0 / 129954-34-3. Sequence MEHFPGP + TKPRPGP. Mass two heptapeptides. Method HPLC.

How fast does a UK order arrive?

Next-day tracked UK delivery is £5 on every order. Discrete laboratory mailer. UK addresses only. Guest checkout — you get a PP- order ID and a tracking number.

Does this vial include the reconstitution kit?

Peptide orders over £75 include USP-grade bacteriostatic water and individually packaged sterile syringes. Under £75 the vials ship without the kit. The kit is a laboratory accessory, not a protocol.
