Knowledge and sourcing
Sourcing safely
Honest about the risks we cannot remove.
People ask where things come from. They ask whether a supplier is real, whether a certificate means anything, and what happened to other members who ordered. If this community refused to discuss it, those questions would simply be answered by sellers instead, which is worse.
So we discuss it, with two commitments. First, we never help anybody import anything and we broker nothing. Second, we say plainly and repeatedly that buying outside a prescription carries risks this community cannot remove — identity, dose accuracy, sterility, contamination, and no recourse if something goes wrong.
Who this circle is for
- You are trying to understand what members have reported about suppliers
- You want to know what a certificate of analysis does and does not prove
- You are weighing up a decision and want it made with open eyes
Agreements here
- Members do not post supplier links, broker orders, negotiate prices or pass contact details here
- Naming a supplier in the circle carries no endorsement; the reference pages say what can and cannot be checked
- We state the irreducible risk every time, and we do not soften it
- Anybody who says a supplier is "verified" is asked what evidence they mean

Two years of TFC orders and nothing to report, which is the report
Pam5 replies
Six TFC orders over two years and every one has looked exactly like the last. That is the report. Paper diary, so I can be precise: quotes back within a working day each time, dispatch…
MKM told me before I paid rather than substituting. A thread about that

One line in my MKM order was out of stock and I was told before I paid, rather than being sent something adjacent and finding out on the doorstep. I want to make a small argument for why…

A facilitator post rather than a member one, because this is about our evidence rather than about a supplier. We hold fewer member-commissioned results for HJ than for any other supplier…
