methodology
the problem
most RUO sites mark the same molecule up 3–5×. some hide the COA behind an email signup. some show one and you have no way to know if it's real. some ship from China and your vials sit in customs for two weeks.
you shouldn't have to choose between a $100 vial with a real COA and a $20 vial that might be glycine.
with us you get both. on verified peptides the lab result is on the product page — id, purity, quantity, and endotoxin confirmed by an independent US lab. standard peptides are sold as-is, no COA, and priced lower.
the real cost. tested. shipped from the US.
how you know it's real
we send every us-lab-verified peptide to an independent US lab before it's listed. the lab confirms id, purity, and quantity per vial, and screens for endotoxin.
the result is right there on the product page. read it before you order. we only list peptides that pass.
the lab confirms it's actually the peptide on the label, not something else.
the lab measures how much of the vial is the peptide vs anything else. published as an actual percentage.
the lab confirms you're getting the dose on the label.
the lab screens for bacterial toxins (endotoxins) — the contamination test that matters most for sterile research material. most vendors skip it.
no "email us
for the COA."
it's right there.
