⭐ What "Verified" means — our testing and vetting process

This list is maintained by the moderation team and it records one thing only: which suppliers members have independently tested, and how consistently the results held. It is a record, not a recommendation.

On the list

SupplierMean purityIndependent tests on fileStanding
QSC (Qingdao Sigma Chemical)97.3%56 · JanoshikListed
WWB (Wuhan Wansheng Bio)96.5%7 · JanoshikListed
GGPeps (Nantong Guangyuan)96.8%11 · Janoshik and PeptideMeterListed

What being listed does and does not mean

  • Does mean: more than one member has paid for a test, on more than one batch, over months, and posted the report.
  • Does mean: no unresolved scam report and no unanswered quality complaint at the time of review.
  • Does not mean that the batch in your hand is the batch that was tested. It is not, and nobody can tell you otherwise.
  • Does not mean endorsement. This board sells nothing, brokers nothing, and takes nothing from anyone on this list.

A supplier comes off the list the moment a quality question goes unanswered, and a removal is recorded rather than quietly done. If you have a test result — good or bad — post it in the review sections and it will be counted.

Right, and one flattering data point from a group buy is not consistency. Consistency means separate batches, separately commissioned, over months.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.

Short answer first, then the reasoning. The pattern that distinguishes a bad batch from an exit is behaviour rather than product. A bad batch comes with communication, a reshipment offer and a batch number. An exit comes with slower replies, pressure toward less reversible payment methods, sudden discounting, and the same reassurance repeated without any new information. The product tells you less than the correspondence does.

Ask again with the specifics and you will get a better answer than this one.

Same position here, arrived at the long way round. The useful checklist is about verifiability rather than presentation. Independent test results commissioned by buyers rather than by the seller, consistency across multiple batches over time rather than one flattering report, a physical address and a company registration that resolve, batch and lot numbers on the actual labelling, and a shipping practice that matches what the material needs. Everything a good-looking website provides is cheap to fake; none of the items above are.
