Know what you’re stakking — including who made it and where it came from.
PepStakk’s supply side is a stack of its own. We expose every layer — from the research vendors upstream to the practitioners who hand you your next vial — so you can see exactly what you’re working with.
We don’t endorse the restaurant. We disclose what we found.
Health departments don’t tell you which restaurant to eat at. They tell you what they saw when they walked the kitchen. PepStakk works the same way for peptide supply. We don’t tell you which supplier, distributor, or clinic to choose. We tell you who they are, what they disclosed, and — where we’ve done the work — what we verified. The transparency is the product.
Four tiers. Two postures. One taxonomy.
Every actor in the peptide supply chain sits in one of four tiers. PepStakk applies one of two trust postures to each: Vetted, where we’ve done the verification work, and Disclosed, where we surface what the partner reported and confirm the disclosure is complete and consistent. The visual treatment differs so a Stakker is never confused about which they’re looking at.
SOURCE
DISCLOSED · research-use-onlyResearch peptide vendors, raw-material makers, and reference standards. Upstream of every other tier — research-grade vendors widely used by self-directed peptide users, vetted for disclosure.
COMPOUNDING
VETTED · disclosure-scored503B outsourcing facilities, 503A compounding pharmacies, and brand owners who put their own name on finished product. PepStakk vets these against the disclosure framework — and the strongest can pursue full certification on top.
DISTRIBUTION
VETTED · license + upstream-disclosedState-licensed wholesalers and drop-shippers between the people who make peptides and the people who hand them to you. We verify the license and require the upstream source to be named — refusal is a hard disqualifier.
CHANNEL
DISCLOSED · partner-reportedWellness centers, aesthetic medicine, telehealth, independent prescribers. PepStakk does not vouch for what happens in the room. We vouch for the integrity of what they disclosed.
Vetted means we did the work. Disclosed means they did.

What you see is what we know.
Every supplier listing on PepStakk shows you the tier, the posture, and the disclosure. Vetted listings show our verification — license, scoring, disclosure tier, certification status. Disclosed listings show what the partner reported and a clear note that PepStakk has not endorsed the underlying practice. Where a Channel partner names a Vetted Compounding source as their upstream, you’ll see a source-link indicator that takes you straight to the supplier’s profile. The chain is the product.
And there’s another stack you should see.
Some of the partners who dispense peptides also review them. PepStakk runs a Clinician Network alongside the Resupply Stack — a vetted directory of licensed practitioners who provide written, async feedback on Stakker protocols. Different surface, different vetting, but the same transparency posture: we tell you who they are, what we vetted, and what we don’t claim.
