Adding a datapoint rather than asking anything.
Ordered from Apex Peptides twice now. First one was fine, second one took three weeks and nobody answered my emails until I opened a card dispute.
Support at Apex Peptides was actually pretty decent when I had a problem, which surprised me given what I’d read.
The Institute testing page has an Index Score of 91 for them if you want actual numbers rather than vibes.
Interested in actual experiences, and please say when you’re guessing.

The figure everyone quotes traces back to a single 2019 paper with n=8. It gets cited as though it were established and it is really not.
Worth clarifying since it comes up a lot: a company's score moves when new results come in, not on a schedule. The score history on each profile shows every change.
oh that makes way more sense, cheers
Mass spec gives you molecular weight, which confirms identity but says nothing about whether the sequence is correct. Two different peptides can share a mass.
