How we test

Every lot goes on the record.

We do not publish one purity number and leave it there. Each batch is sampled, sent out, and reported against the lot number you can read on your own vial.

What gets run

  • HPLCReverse-phase HPLC with UV detection gives the purity figure as a percentage of total peak area.
  • MSElectrospray mass spectrometry confirms the molecular weight matches the sequence claimed on the label.
  • LALWhere applicable, endotoxin is measured by LAL against USP <85>, and the report is attached alongside the COA.
  • QCAppearance, seal integrity and label-to-lot agreement are checked by hand before a batch is listed.

01

Synthesis

Solid-phase synthesis at a contracted facility, then reverse-phase purification and desalting.

02

Fill & lyophilize

Vialed under nitrogen, freeze-dried to a stable cake, crimp-sealed and printed with its lot.

03

Independent testing

A pulled sample goes out for HPLC and mass spec. The result gets published, pass or fail.

04

Cold-pack dispatch

Gel packs, insulation, tracked label. Out the door the same day before 2PM CT.

Status by compound

Where every lot stands

29 of 30 published

Reports appear here as each lot clears the lab. A blank slot means the batch is still being tested or the report has not been uploaded yet — never that a lot shipped untested.
