Why buy Selank Peptide from TrueBond Labs
Tested by an outside lab
For our published Selank lot, an independent third-party lab reported HPLC purity of at least 99% and confirmed identity. Read the full Selank certificate of analysis and compare its lot code with your vial. The PDF is there to save for your records.
Seven residues, 10mg
Selank is a seven-residue peptide built on tuftsin, supplied as 10mg of freeze-dried powder in a sealed 3 mL vial with the lot code printed on the label. It's the only size we stock.
Selank or Semax
Selank is often compared with Semax, another seven-residue peptide that ends in the same tail. Both have published certificates, so you can read them side by side. Our third-party tested peptides page lists every product with a published certificate.
What is Selank?
Selank is a synthetic peptide of seven amino acids: Thr-Lys-Pro-Arg-Pro-Gly-Pro. The first four are tuftsin (Thr-Lys-Pro-Arg), a naturally occurring tetrapeptide, and a Pro-Gly-Pro tail completes the chain.
Selank appears in published laboratory research on neuropeptide signaling. Semax shares the same Pro-Gly-Pro tail, but the two start from different parent sequences: Selank from tuftsin, Semax from a short fragment of ACTH.

Selank Peptide: frequently asked questions
Selank vs Semax: what is the difference?
Both are synthetic heptapeptides, and both end in Pro-Gly-Pro. They start differently. Selank begins with tuftsin (Thr-Lys-Pro-Arg), while Semax begins with the ACTH(4-7) sequence (Met-Glu-His-Phe). We carry both as 10mg vials, each with its own lot code. Our Selank vs Semax page lays the two out side by side.
Is Selank the same as tuftsin?
No. Tuftsin is the four-residue peptide Thr-Lys-Pro-Arg. Selank starts with tuftsin and adds Pro-Gly-Pro, for seven residues in all. They're different compounds, and we sell Selank as a 10mg vial with its own certificate.
How do I check the certificate for my Selank vial?
Find the lot code on your vial and look it up on our lab reports page. If it's listed, the certificate filed under that code covers your lot, and its PDF shows the test date and purity figure as the lab printed them.
How should I store Selank?
Keep the sealed vial in a freezer at −20°C (−4°F). Lyophilized Selank kept that way holds for 24 months or more. Keep it out of the light and avoid repeated freezing and thawing.
