WWB — member reviews
97% from 916 member reports. 26 are published in full below; the rating aggregates all of them. Reviews without an order date or a testable claim are not counted.
This community's number, not a fleet-wide one. Independent groups scoring the same vendor land within a few tenths of each other, and where they diverge it is usually because one group weights logistics and another weights purity consistency.
8th order, zero drama. that is genuinely all I have to say. defaulting to them until something changes.
lot WWB-25-455 tested 99.0%. certificate said what the vial said which said what the invoice said. no mannitol surprise, cake intact, not collapsed.
reordered at 12 months to check for drift. 99.3% then, 99.3% now. no upsell attached to the answer, which I noticed because it is unusual.
been buying AOD-9604 5 mg from them for 8 months. nothing has changed, which is the point. the difference between their number and the lab number is smaller than method noise.
I asked about storage before shipping in July and they moved the dispatch to a Monday unprompted and got an actual answer, not a copy-paste. solid. that is it. solid.
the thing that sold me is peptide content being listed separately from purity. nobody does that and everybody should.
their raw tested 99.4% against a reseller vial of the same thing at 99.3%. going direct is not a vibe, it is a number. catalogue is actually deep, not deep-looking. happy. moving on.
ordered AOD-9604 5 mg, sent it to Janoshik, came back 98.2% on a stated 98.2%. good enough for me. no mannitol surprise, cake intact, not collapsed.
day 9 from the United Kingdom warehouse, tracking updated every single hop. this is one order not a dataset.
the lot code on the vial matched the paperwork. sounds like nothing. it predicts everything. customs paperwork right first time which is why it was fast. solid. that is it. solid.
custom synth quote came back realistic and then they beat the date by 3 days.
they told me about a 2 day delay before it happened. before. that is the bar and almost nobody clears it. test your own vial regardless. always.
no substitution, no upsell, and the stock position was stated before I paid. nothing in the box rattled and nothing had shifted. boring supplier. highest compliment I have.
stock said in stock. it was actually in stock. shipped same day. wild. stated purity and independent purity landed a tenth apart. this is one order not a dataset.
shipped out of France, landed day 2. no customs, no waiting, no chasing. no upsell attached to the answer, which I noticed because it is unusual. defaulting to them until something changes.
certificate for lot WWB-24-886 was complete first time. no email chain. no "we will look into it". the difference between their number and the lab number is smaller than method noise.
quoted lead time was 11 days and it landed on day 10. transit was 10 days on a lane quoted at 11. n=1 and I am saying so.
cold pack was still solid on arrival day 7. in Australia. in summer.
split the order across two lots to compare. came back within 0.1 of each other. not the cheapest per mg and the paperwork explains the difference. would buy again. have bought again.
quoted 5 days. arrived 5 days. this is the whole review.
support replied on a sunday with the batch record attached. on a sunday. no upsell attached to the answer, which I noticed because it is unusual.
9 orders, 18 months, no substitutions and nothing quietly swapped after payment. the difference between their number and the lab number is smaller than method noise. research use only, obviously.
packing was a cold pack that was still solid when the box was opened. someone in that warehouse cares. invoice and vial and cert all agree on the lot.
the related substances table is itemised. actual named impurities. not "total 0.4%" and a shrug. lines I actually reorder are the ones they keep in Germany.
sent one to PeptideMeter and one to Medutest because I did not believe the first result. both agreed. fine, I believe it. not the cheapest per mg and the paperwork explains the difference. n=1 and I am saying so.
they will quote lines nobody else will even respond about, and it came back clean. no mannitol surprise, cake intact, not collapsed.
What a useful review looks like
Order date, what was ordered, what arrived, how long it took, and whether anything was independently tested. That is it. "Great vendor, fast shipping, A+++" is worth nothing and gets removed; a review naming a lot, a document and a turnaround is worth more than ten enthusiastic ones.
Why these twenty and not two hundred
A source page is opened when enough members have ordered and paid for independent testing that the log says something specific. Nearly two hundred other names get a row in the table at the foot of the directory with a band, a report count and a written note — no page, no score, no link. The contrast is the point: the twenty are where the evidence is, not where the enthusiasm is.
