Neuropeptide analogues

Semax is a heptapeptide built on the ACTH(4-10) fragment with a stabilising Pro-Gly-Pro tail and is studied for BDNF / NGF expression. Selank is a heptapeptide analogue of tuftsin studied for GABAergic and neuroimmune signalling. DSIP, the delta sleep-inducing peptide, is a reference ligand in sleep-architecture and circadian research.

Oxytocin is the classic neurohypophysial nonapeptide for oxytocin-receptor studies, and PT-141 (bremelanotide) is a melanocortin analogue with a preference for the MC4 receptor.

Vials and sprays

Every compound in this range is available as a ready-made 15 ml nasal-spray solution, and most also as a lyophilised vial — useful when comparing formats with the same peptide.

Orders placed before 12:00 UK time (Mon–Fri) are dispatched the same working day by tracked delivery, free on UK & EU orders over £50.

Frequently asked questions

What is the difference between Semax and Selank?

Semax is derived from ACTH(4-10) and is studied mainly for BDNF and melanocortin-pathway signalling; Selank is derived from tuftsin and is studied for GABAergic tone and neuroimmune signalling.

Is PT-141 the same as Melanotan II?

No. PT-141 (bremelanotide) is a cyclic heptapeptide related to Melanotan II but with a stronger preference for the MC4 receptor.

How should neuropeptides be stored?

Lyophilised vials at −20 °C, protected from light; nasal sprays at 2–8 °C, tightly closed.

Are neuro-research peptides for human use?

No. Everything in this range is supplied strictly as laboratory research material for in-vitro use. It is not a medicine, food, supplement or cosmetic and is not for human or veterinary use.
