Our Compounds
Two compounds. Zero compromises.
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.
Selank Nasal Spray
Nasal Spray · 20mg
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.
The Data Layer
Every batch. Every test. Transparent.
Every compound we ship includes a Certificate of Analysis from Janoshik Analytical, an independent third-party lab. Purity is verified via HPLC and LC-MS/MS — the same methods used in pharmaceutical quality control. No self-reported numbers, no shortcuts. The data is there for anyone who wants to check.
Certificate of Analysis
Why Helm
Research-grade. No shortcuts.
Research Grade
Pharmaceutical-standard synthesis
Our compounds are synthesized to the same purity standards used in clinical research — not cobbled together from the cheapest available source. Every batch starts with verified raw materials and ends with independent lab confirmation.
Third-Party Tested
Independent verification, every time
Janoshik Analytical tests every batch we produce using HPLC and LC-MS/MS. The results are published with each product — not hidden behind a support ticket or a "contact us" form.
Built Different
Direct to your bench
No middlemen. No markup from aggregators. We control synthesis, testing, and fulfillment. That means better compounds at fair prices, shipped directly to you.
