Alright everyone, time for a proper WWB tirzepatide write-up. I've been ordering from Wuhan Wansheng Biotech since November 2025 and I'm now four months and five orders in. All tirzepatide 30mg vials. Here's the complete breakdown with testing data: Order 1 (Nov 12, 2025): 5x tirz 30mg — $32/vial, $160 total + $25 shipping. BTC payment. Shipped from Wuhan, arrived East Coast US in 16 days. Sent one vial to Janoshik — HPLC came back 98.6% purity. No degradation products above 0.3%. Order 2 (Dec 8, 2025): 10x tirz 30mg — $28/vial, $280 total, free shipping. Same BTC payment. 13 days to arrive. Did not test this batch independently but reconstituted perfectly — clear solution, no particles. Order 3 (Jan 15, 2026): 10x tirz 30mg — $28/vial again. 19 days shipping (hit some delay, probably holiday backlog). Sent to Janoshik — 99.1% purity. Actually higher than the first batch. Order 4 (Feb 2, 2026): 15x tirz 30mg — $26/vial at 15 qty, $390 total. 12 days shipping. Fastest yet. Order 5 (Mar 1, 2026): 10x tirz 30mg — $28/vial. Currently in transit, tracking shows it cleared US customs yesterday. Total spent: roughly $1,060 across all orders. Product has been consistent throughout. Packaging improved between Order 1 and Order 3 — they started double vacuum-sealing and including better cold packs. Lyophilized cakes look uniform, white, well-formed every time. Subjectively, the tirz has been performing as expected. Appetite suppression kicks in about 24 hours post-injection. No unusual side effects beyond the expected GI stuff the first two weeks. Blood glucose control has been excellent — A1C went from 6.1 to 5.4 over this period. Would I recommend? Yes, with the caveat that you should test your first batch independently. The consistency has earned my trust but verification matters.

That 99.1% on Order 3 is outstanding. Pretty rare to see tirz testing that high even from domestic compounders. Did Janoshik flag any residual solvents or endotoxin concerns on either test? Also curious about the reconstitution — are you using BAC water? What volume per vial?

Janoshik's standard panel doesn't include endotoxin — that's a separate test I haven't sprung for. No residual solvent flags though, both certificates were clean. Reconstitution: I use 1.5mL bacteriostatic water per 30mg vial. Gives me 20mg/mL concentration. I draw 0.375mL for a 7.5mg dose, which is what I've been running. Dissolves within about 30 seconds of gentle swirling — never had to vortex. Stored at 2-8°C after reconstitution and I've used vials up to 28 days post-reconstitution without noticeable potency drop.

The $26/vial at 15 qty is solid. I've been comparing and that's cheaper than QSC's China direct at 30mg ($29/vial last time I checked). Do they offer further discounts at 20+ vials? I order for a small group buy with three friends.

Good question. I asked my contact about 20+ pricing and they quoted $24/vial for 20-29 units and $22/vial for 30+. At 30 vials that's $660 for what would cost you like $5,000+ retail if you could even get name-brand tirz at that dose. The group buy idea makes a lot of sense at those tiers. One caveat: above 20 vials they split the shipment into two packages to reduce customs risk. Adds a couple days but I'd rather have two smaller packages clear independently.
