Long post, sorry. TL;DR at the bottom if you don’t want the whole thing.
Half of what’s written about SLU-PP-332 online is copied from the same three forum posts from 2019. I can’t find an original source for most of it.
What bugs me about SLU-PP-332 is how confident everyone is. Nobody hedges. Everyone has a protocol.
Started looking at SLU-PP-332 because a friend swears by it. He also swears by cold plunges and sleeping with his phone in another room, so, grain of salt.
The Institute testing page has 2 published tests on SLU-PP-332 if you want actual numbers rather than vibes.
The part I keep getting stuck on is that everyone’s confident and nobody agrees, which usually means the evidence is thinner than the discussion.
TL;DR: SLU-PP-332 might be fine, might not, and the way to tell apart seems to be documentation rather than price. Would appreciate other perspectives.

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.
