Who supplies the stack
Clav Stack Directory
Running the Clav stack means dealing with more than one supplier, and the weak link is rarely the peptide itself. It is the pharmacy that will not show you a lot number, the lab that takes three weeks to return an assay, or the telehealth service that will not order the bloodwork you actually want tracked. This page collects the businesses that handle those pieces, each one submitted by the company itself and read through by hand before it goes live.
The directory is not reachable right now. If this persists, thetcs_business_listingstable may not exist yet.
What a listing here confirms
That the business exists, sells what it says it sells, and was willing to publish a name and a contact address. That rules out the storefronts which appear and vanish inside a quarter. It does not confirm purity, batch consistency, or how a company behaves when an order goes wrong — those are answered by lot-specific certificates of analysis and by ordering small the first time.
Why a stack needs more than a vendor
A single-compound protocol needs one supplier. A stack needs someone to assay what arrives, someone to order and read the bloodwork, and often a pharmacy that can compound what a research vendor will not sell. Splitting those roles across categories is deliberate — the checks you apply to a testing lab have almost nothing in common with the checks you apply to a peptide vendor.
How the categories are meant to be used
Filter to the role you are trying to fill rather than browsing the whole list. A compounding pharmacy and a COA lab are not competitors and ranking them against each other tells you nothing. Within a category the businesses are comparable, which is the only context where comparing them is useful.
Common questions
Is a listing an endorsement?
No. A listing means the business submitted its own details and those details were read before publication. Nothing here has been product-tested and no supply chain has been audited.
Does it cost anything to be listed?
No, and there is no paid placement, so the order carries no commercial meaning.
How do I get listed or corrected?
Send the company name, website, contact address and the categories you operate in. Corrections to an existing entry need the URL and what is wrong with it.
Why are some categories empty?
Because nobody in them has submitted yet. Empty categories stay visible so the gaps are obvious rather than hidden.
