BPC-157 is the most-asked-about peptide on the internet right now. Real animal data, almost no human data, a market full of vendors making big claims. Here's the honest version.
A friend just starting peptides got a three-in-one vial in the mail. The label looked sketchy at first glance. Then the actual data showed something different. The lesson is what changes when you stop trusting the photo.
Buying peptides online is harder than it looks. The market is full of vendors making big claims and shipping mixed-quality product. Here's the actual landscape, the red flags, and what verified vendors look like.
We've been running the same 11-signal rubric against every GLP-1 telehealth and pharmacy operator we could find. 77 vendors across 19 regions, scored on the same axes. The pattern that emerged was not what we expected.
The peptide market splits into licensed pharmaceutical, licensed compounded, and research-chemical-flavored compounded. The middle category has wide quality variance. Here's how to actually tell them apart.
Vendor pricing pages are designed to make decisions easy at the cost of clarity. Here's the patterns that signal you're about to overpay or land at the wrong vendor entirely.
Lilly has redesigned the Mounjaro pen multiple times since 2023 and ships region-specific variants. Most pen-appearance changes are legitimate. The few that aren't matter.

A short guide to the seven things on every /vendor/<id> page. The score, the verdict, the per-signal bands, the channel description, the regulatory citations, and the visit-or-hold CTA. What each piece means and what to do with it.
The Panya catalog scores 60+ vendors on the 11-signal rubric. Some land in routable, some in conditional, some in hold. The hold-verdict scorecards are the most useful pages we publish · here is why we keep them and what they do for the people who land on them.
Our public rubric, current as of May 2026. Each of the 11 signals scored 0 to 100, with what a low/mid/high band looks like in practice. The same rubric on every /vendor scorecard, no exceptions.
Heat degrades peptides. But not all peptides, not at all temperatures, not at all durations. The honest version of the cold-chain question.
The five things that matter on a COA, the three things that do not, and the one question that separates a serious vendor from a cargo-cult operator.
Most peptide comparison sites are really just attack blogs. We do it differently, on purpose. Here is the logic.
