Selank and Semax are two synthetic seven-amino-acid peptides that researchers often study side by side in neuroscience lab work. Simple Peptide sells both as US manufactured research peptides, including the Semax/Selank Blend. We also post third-party test results for every batch on our COA page.
Selank and Semax
Selank and Semax are short synthetic peptides first developed by Russian research groups, with Semax based on a fragment of the hormone ACTH and Selank based on tuftsin, a natural four-amino-acid peptide.
Because the two share a similar design, labs often order them together. In fact, both end with the same Pro-Gly-Pro tail. You can read published work through a PubMed search for Selank and Semax. Then compare single vials, the blend and the strip format in our nootropic category.
Picture a lab that plans to compare each peptide alone and then as a pair. Usually, that means three orders from three sellers, each with its own paperwork. With Simple Peptide, the team can buy Selank and Semax vials plus the blend in one order. As a result, every certificate sits in one folder, and lot numbers match their reports in minutes.

Semax peptides
Semax peptides are research compounds built on the sequence Met-Glu-His-Phe-Pro-Gly-Pro, an analog of the ACTH(4-10) fragment, which researchers study in lab work on brain signaling and neurotrophic factors.
The ACTH fragment gives the molecule its core, while the Pro-Gly-Pro tail sets it apart. For that reason, papers describe Semax as its own compound rather than a copy of ACTH. So when you search the literature, use the full name and note the sequence in your records. Also, keep the lot number next to that sequence, so a later reorder lines up with the earlier batch.
Say your team needs a single Semax vial for a baseline arm. First, open the Semax 10MG listing and check the lot report. Next, decide whether you also need the blend for a second arm. Finally, add both to one order so your records stay together.
Neurotropic
Selank peptide
Selank peptide is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, built by adding a Pro-Gly-Pro tail to tuftsin, and researchers study it in lab models of stress-related and immune signaling.
Tuftsin itself is a natural four-amino-acid peptide. However, Selank adds three more amino acids to that core. Similarly to Semax, the tail is the feature that makes it a distinct research compound. In addition, that shared tail is one reason many papers place the two peptides in the same discussion. So it helps to keep both names, both sequences and both lot numbers in one file.
Here is a common question from buyers. Do you need single vials or a combined format? For single-compound work, the Selank 10MG vial keeps things simple. Meanwhile, labs that want a dissolvable format can compare the Melts Pro Selank + Semax strips. Either way, check the COA first, then add the format you need to your cart.

Frequently asked questions
What is the difference between Selank and Semax?
Semax builds on a fragment of ACTH, while Selank builds on tuftsin. Both are seven-amino-acid peptides with a Pro-Gly-Pro tail.
Can I buy Selank and Semax together?
Yes. We sell Selank and Semax as single vials, as a combined blend and as Melts Pro dissolvable strips.
Where can I see test results?
Visit our COA page to read the third-party report for each batch. You can also contact our team with lot questions.
Can people use Selank and Semax?
No. We sell Selank and Semax for laboratory research use only, so they are not for human consumption.
