About LGCY Peps
Built for researchers who read the data
LGCY Peps started with a frustration every researcher knows: a purity number on a label, and nothing behind it. We set out to build the supplier we wanted to buy from.
Every compound we list is tested by an independent lab, matched to its lot number and backed by a certificate of analysis you can read before you order. No health claims, no guesswork, just research-grade peptides and the paperwork to prove it.
What we stand for
Five principles behind every vial
The rules LGCY Peps was built on. They decide what we list, how we test it and how we talk about it.
Every compound ships with a certificate of analysis from an independent lab. If a number appears on our site, there is a report behind it.
We test beyond purity for endotoxins, sterility, heavy metals and residual solvents, because a clean chromatogram is not the whole picture.
Our products are sold strictly for laboratory research. We label, describe and support them that way, with no health claims.
Questions about reconstitution, storage or a COA go to someone who can actually read one, not a script.
Same specification, same testing, every batch. Reproducible research starts with a reproducible supply.
How a vial reaches you
From synthesis to your bench
Five stages, the same for every lot. Nothing ships until the paperwork does.
- 01
Synthesis
Each compound is synthesized to our specification in GMP-compliant facilities.
- 02
Purification
Batches are purified and freeze-dried to a stable powder before testing begins.
- 03
Independent testing
A third-party lab screens identity, purity, endotoxins, sterility, heavy metals and solvents.
- 04
COA published
Results are matched to the lot number and published, so you can read them before you order.
- 05
Packed and shipped
Orders before 2PM EST leave the same day in discreet, protected packaging.
