Frequently asked questions

Simple — we buy straight from trusted research-grade makers and skip the middlemen, run a lean team, and keep our markup small. You get the same 99%+ purity the big US sellers offer, just without paying extra for the name.

Every batch is checked by an outside lab: HPLC confirms purity and mass spec confirms it’s the right compound, at 99% or higher. We post each batch’s certificate of analysis on its product page as testing wraps up.

We stand behind 99%+ purity. If an independent test ever comes back lower, we’ll replace your order or refund it in full — your choice.

Anyone 21 or older can order, as long as you agree the products are for lab research only (our terms spell this out). No license or special approval needed — everyone’s welcome.

In-stock orders placed before 2pm ET on a weekday usually go out the same or next business day. You’ll get a tracking email the moment your label is made. Pick standard (3–5 days) or express (3 days or less) at checkout.

Everything we sell is for lab research only — not for use in people or animals, and not for diagnosis or consumption. It’s a line we don’t cross.

Credit and debit cards, PayPal, and select crypto. Verified labs and universities can also set up invoicing with net terms — just reach out.

Peptides arrive freeze-dried and travel fine at room temperature (cold-packed when needed). Store sealed vials at –20°C. Once mixed with bacteriostatic or sterile water, keep them refrigerated and use within the window on the certificate. Try not to freeze and thaw over and over.
