About

Research-grade synthetic peptides, assembled as a reference catalog.

Bench Grade Peptides LLC is a specialty research-chemical distributor based in the United States. We supply lyophilized synthetic peptides to contract research organizations, university and private laboratories, longevity and biotech companies, and qualified researchers — for laboratory research use only.

The supply chain

Every peptide we sell is made in the USA at a US facility using solid-phase synthesis (SPPS), from active pharmaceutical ingredient we source both domestically and internationally. Every supplier is vetted before a lot is accepted, and no lot ships on a supplier’s word alone.

From a research-customer standpoint that means two things: every lot is tested in the United States by a laboratory with no stake in the result, and the Certificate of Analysis you receive is issued against the vial in your hand rather than a specification sheet.

Verification, every lot

Before any lot is released it’s sent to an independent third-party laboratory for HPLC purity analysis and mass-spectrometry identity confirmation. The laboratory issues a Certificate of Analysis in Bench Grade Peptides’ name, which we publish on the product page and include with every vial.

The COA carries the lot number, synthesis date, HPLC purity percentage (target ≥99.0%), mass-spec confirmation of the target molecular weight, residual-solvent results, and the third-party analyst’s signature. Every outbound vial traces back to that COA via its lot number stamped on the label.

The Bench Grade Guarantee

If any vial you receive is independently re-tested at a certified third-party laboratory and the result disagrees with our published COA, we refund the test fee, the order, the shipping, and add $100 on top. No fine print. You pick the laboratory; we honor the result. We can stand behind this because every lot was already independently tested before it shipped — the guarantee just makes that backing falsifiable.

What we do not do

We do not compound. We do not dispense. We do not formulate for human or veterinary administration. We do not advise on dosing, scheduling, or therapeutic use of any compound in our catalog. We are not a pharmacy, a dietary-supplement company, or a medical-device manufacturer. Our products are supplied for laboratory research use only and have not been evaluated by the FDA for any other purpose. See the Compliance page for the full RUO statement.

How we operate

We ship US-domestic only. Standard shipping is free on every order; 2-Day, Overnight, and Priority Overnight are available as flat-rate upgrades. We ship the same business day: payment cleared before 2 PM ET leaves that day. We accept credit and debit cards, processed securely by PayPal.

Subscriptions are flat-rate plans ($229 for 2 vials, $319 for 3, $489 for 5, $739 for 8). Each plan ships the same fixed amount every cycle regardless of cart price; the per-vial economics beat one-shot buys at every tier.
