Everything we test, and what the number means.
One price covers three separate answers. Identity says the molecule in the vial is the one on the label, measured by intact mass on LC-MS. Quantity says how much of it is actually there. Purity says what percentage of the material is the compound and what is everything else, reported by HPLC-UV as percent area. A purity number on its own answers none of the first two questions, which is why we do not sell it on its own.
Three answers, one price.
Identity
Intact-mass LC-MS measures what the molecule weighs and compares it against the expected value. Compounds that get confused on labels, like tirzepatide and semaglutide, are hundreds of daltons apart. One run settles it.
Quantity
The measured amount of compound in the sample you sent. A vial can be pure and still be short, and purity testing alone will never tell you that.
Purity
Reversed-phase HPLC-UV, reported as percent area, with system-suitability standards run on either side of your sample so the number has something to stand on.
How a sample becomes
a certificate.
Every sample in the catalog moves through the same five steps. No shortcuts for rush orders. No unnamed hands in the middle.
Intake.
Your sample arrives. We photograph it, weigh it, log every detail, and assign a tracking number that follows it onto every page.
Prep.
A named analyst prepares the run: dissolutions, dilutions, internal standards. Their initials go in the log.
Run.
HPLC-UV for purity, LC-MS for identity, and quantitative analysis for the amount present, with system-suitability standards bracketing your sample on either side.
Review.
A second analyst reviews the chromatogram independently. Nothing ships with one set of eyes on it.
Sign.
The COA is digitally signed, hashed, and published. Anyone with the link can verify the signature against the raw data.
Four kinds of sample.
Prices and current availability live in the ordering catalog. These pages explain the methods behind each one.
Peptides
BPC-157, TB-500, GHK-Cu, CJC-1295, ipamorelin, and the rest of the research peptide catalog. Identity, quantity, and purity in the base test.
GLP-1 compounds
Tirzepatide, semaglutide, retatrutide, liraglutide. Long side chains are the hard part of the synthesis, and the first thing missing when a batch is made badly.
Small molecules
Compounds like tesofensine, NAD+, and MK-677, run on the same instruments with methods matched to the chemistry.
Optional add-on testing
Sterility, endotoxin, and heavy metals sit outside the base test and are ordered alongside it. Each is priced in the catalog.
HPLC analysis on its own
High-performance liquid chromatography for purity assessment and lot documentation, including the method parameters behind the number.
Bulk and custom work
Compounds outside the standard catalog, and larger batches from vendors and labs, are quoted individually.
