Selank (TKPRPGP) is a synthetic heptapeptide analog of tuftsin, a naturally occurring immunomodulatory peptide, extended with a C-terminal Gly-Pro sequence to enhance metabolic stability. In preclinical studies, Selank has been investigated for its anxiolytic and nootropic properties, with research suggesting modulation of GABAergic neurotransmission, BDNF expression, and monoamine metabolism. Each bottle delivers 20mg of research-grade Selank in a 10mL metered nasal spray (2mg/mL, ~200mcg per actuation). Purity verified at ≥99% via HPLC and identity confirmed by LC-MS/MS. Third-party tested by Janoshik Analytical. For research use only — not for human consumption.

Semax Nasal Spray

Nasal Spray · 30mg

Semax (MEHFPGP) is a synthetic heptapeptide derived from the adrenocorticotropic hormone (ACTH) fragment 4–10, stabilized with a C-terminal Pro-Gly-Pro tripeptide to enhance enzymatic resistance. In preclinical research, Semax has been studied for its interactions with melanocortin receptors and its potential to upregulate brain-derived neurotrophic factor (BDNF) expression, supporting investigations into neuroplasticity, cognitive function, and neuroprotection. Each bottle delivers 30mg of research-grade Semax in a 10mL metered nasal spray (3mg/mL, ~300mcg per actuation). Purity verified at ≥99% via HPLC and identity confirmed by LC-MS/MS. Third-party tested by Janoshik Analytical. For research use only — not for human consumption.
