Why Helix Club
Built for people whose results have to hold up
Join a community of researchers
Every purchase unlocks access to the Helix research community. Compare lab notes, review methodology, and reference current documentation on each compound.
Research-grade quality, researcher-friendly pricing
U.S.-based provider with in-house manufacturing. Every batch undergoes third-party identity and content testing with full documentation — without the markup that keeps high-purity supply out of reach.
Expert support whenever you need it
Anywhere in the US, as fast as next day
Extensive research library at your fingertips
Every compound page links the peer-reviewed literature behind it — journal, year, and PMID — so the evidence is one click away instead of one search away.
Free shipment protection on every order
Every order is protected against damage, loss, or theft in transit. If your product arrives damaged, we replace it at no cost.

Answers
Frequently asked questions
Everything you need to know about peptide research supply.
Every lot is released at 99%+ identity purity. Purity is quantified by reverse-phase HPLC and identity confirmed by mass spectrometry at an ISO/IEC 17025 accredited third-party lab. The full seven-point QC panel — purity, net peptide content, identity, HPLC conformity, heavy metals, sterility, and endotoxin — is published on each product page.
A CoA is the lab document tying a specific lot number to its test results. Read it top-down: confirm the lot number matches your vial, check that identity matches the compound you ordered, then compare labeled mass against measured net peptide content. Anything at or above the labeled value means you received full stated content.
Helix H₂O is sterile bacteriostatic water containing 0.9% benzyl alcohol — the standard diluent for reconstituting lyophilized research compounds. The preservative allows multiple withdrawals from the same vial within 28 days of first puncture.
Store lyophilized material at -20°C, desiccated and protected from light. It remains stable at room temperature during transit. Once reconstituted, store at 2–8°C and avoid repeated freeze-thaw cycles, which degrade peptide integrity faster than storage temperature alone.
Most lyophilized peptides carry a 36-month shelf life when stored correctly at -20°C. Coenzymes such as NAD+ are hygroscopic and carry a 24-month window. Each product page lists its specific shelf life under Stability Information.
Orders placed before the daily cutoff ship the same business day from the United States, with most domestic addresses receiving delivery in 2–3 days and overnight available at checkout. Cold shipping is not required — lyophilized material is stable at ambient temperature for the duration of transit.
