Planning to put in an order with Peptide Protocol (peptide-protocol.com) soon, so I'm comparing them against a couple other suppliers before I commit. Figured I'd ask here first. Things I'm trying to sort out: does the product catalog show full sequence and purity, and are the third-party COAs lot-specific or just representative documents?
That's usually where vendors start looking different from each other.
Pricing too — are the published prices per vial/unit, and does that include or exclude shipping, cold-chain, and payment? What I can find online doesn't spell it out. Not trying to dunk on them, just want to know what I'm actually comparing.
If you've ordered, what did the paperwork look like when it showed up?
