HPLC vs Mass Spectrometry: What Each Test Actually Proves
Chromatography measures homogeneity, mass spectrometry measures identity. What each proves, what it cannot see, and why one without the other is incomplete.

Compounds researchers ask for most
All in stock. Tap any locked price and three quick questions opens the whole catalog.
For research use only. Not for human consumption. Not FDA approved.
How this works
Read everything free. Pricing takes a minute.
Most suppliers hide the science and lead with a price. We do the reverse, because the people who read a certificate of analysis before they buy are the people we want to sell to.
Read everything, free
Chemistry, sequences, mechanisms under investigation, storage guidance, and every batch certificate. No account, no email, no gate.
Answer three quick questions
Tap through three multiple choice questions, then your name and email, one screen at a time. Pricing and live availability open across the catalog, and you get a reading list. Free, and no password to create.
Request, then receive
Check out on the site. Your order page opens straight away with the payment details and the status, and tracking lands on that same page the moment it ships.

Start with the compound, not the cart
Each hub covers discovery, chemistry, the mechanisms under investigation, and an honest read on where the evidence actually stands.
Synthetic gastric pentadecapeptide
BPC-157
BPC-157 is a synthetic pentadecapeptide studied in rodent injury models for its interactions with angiogenic and cytoskeletal signaling pathways.

A certificate is only worth the batch it names
Generic certificates get recycled across lots and suppliers. Ours are tied to the batch code printed on your vial, run by an independent lab, and published here whether the number flatters us or not.
What the laboratories test for
- HPLCChromatographic purity by area under the curve22/24
- Mass specMolecular identity against expected mass12/24
- EndotoxinBacterial endotoxin units per milligram13/24
- SterilityCompendial sterility test11/24
- Heavy metalsElemental impurities, parts per billion2/24
Panels vary by laboratory, so these are counts across the current lots rather than a promise about all of them. Each report names the assays it covers.
