Why Alto
Purity isn’t
a feature.
It’s the floor.
Every compound in our catalog is tested by independent third-party labs. A certificate of analysis ships with every order — no fine print, no opaque supply chains. Your results depend on what’s in the vial; so does our reputation.

Science you can verify
Purity threshold
Every lot must meet ≥99% purity on HPLC testing before it ships. No exceptions. A COA is included with every order.
Ships within
Orders confirmed before the daily cutoff ship the same business day. B2B accounts get priority allocation and a dedicated contact.
Party tested
Independent lab verification on every production run. Certificates of analysis are issued per lot and available on request at any time.
B2B Partner Program
Built for repeat buyers
What approved accounts get from day one.
01 — Pricing
Tiered wholesale pricing
A pricing sheet built around your volume, not a public retail list. Tiers step down as monthly volume grows.
02 — Allocation
Priority stock and dispatch
Partner orders are allocated first when a lot is released and ship the same business day when confirmed before cutoff.
03 — Documentation
Lot-level paperwork, on file
A COA for every lot you receive, kept on file for your account and re-issued on request for audits and records.
Our commitment
Research-grade peptides.
Nothing to hide.
We built Alto because researchers deserve a peptide supplier with nothing to hide. No gray-market sourcing. No ambiguous purity claims. Just research-grade compounds, independently verified and documented lot by lot.
