The certificate matched the vial before I even opened the box.
Lot number on the label, lot number in the library, same HPLC trace. That is the whole reason we moved our ordering here.
Home › Why us
Why do researchers order from us?
Because the number on the label is the number in the report. Here is how the vial gets from synthesis to your bench, and who checks it along the way.
Made in the USA
Synthesized here, not re-labelled
Every compound is made by solid-phase peptide synthesis in our [City, State] facility, purified by preparative HPLC and filled under controlled conditions. We do not resell imported bulk under our label.
7
Tests per lot
Identity, purity, net peptide content, heavy metals, endotoxin, sterility and batch consistency.
18
Days of scrutiny
From synthesis to a published certificate before the lot is listed.
0
Lots sold without a COA
If the certificate is not in the library, the lot never shipped.
Independent testing
Who tests the peptides, and what do they test?
An accredited US laboratory we do not own runs every assay. We publish their report, not a summary of it.
What researchers say
Rated 5.0 by the labs that order here
Shipped the same afternoon, cold pack included.
Ordered at 11am, tracking by 3pm, on the bench two days later. The reconstitution guide saved a call to the supplier.
First supplier whose COA lists endotoxin, not just purity.
We run cell work, so the LAL number matters more than the headline percentage. Every lot we have bought has it.
Support answered a lot question in under an hour.
Asked about storage after reconstitution for a GLP-1 compound. Got a straight answer with the certificate window, no upsell.
Purity on the report was 99.6. Our own HPLC read 99.5.
We re-test everything that comes in. This is the first vendor in three years whose number we could reproduce within a tenth of a percent.
Bundles ship as separate lots with separate certificates.
Other suppliers co-mingle blends with no paperwork. Here every vial in the repair pair had its own COA and lot number.
What we will not do
- Claim a purity we have not measured on the lot you receive.
- Describe dosing, protocols or effects in humans. Everything here is for in-vitro research.
- Show the same offer twice. The first-order code appears once, then stays out of your way.
- Ship a lot whose certificate is not already public.
