Been lurking for months and finally pulled the trigger on Wuhan Wansheng Biotechnology (WWB). I've now placed 3 separate orders over the past 4 months and sent samples from each batch to Janoshik for HPLC testing. Figured I'd share results for the community.
Order 1 (Nov 2025): Semaglutide 10mg x10 vials
- Janoshik HPLC: 99.1% purity
- Cost: $28/vial
- Shipping: 14 days to US East Coast
Order 2 (Jan 2026): Semaglutide 10mg x20 vials + Tirzepatide 15mg x10
- Sema Janoshik HPLC: 98.7% purity
- Tirz Janoshik HPLC: 98.4% purity
- Cost: $24/vial (bulk discount on sema), $32/vial tirz
- Shipping: 11 days
Order 3 (Feb 2026): Semaglutide 10mg x30 vials
- Janoshik HPLC: 99.4% purity
- Cost: $22/vial at 30 qty
- Shipping: 16 days
All three orders came through without issues. Packaging was solid — vacuum sealed, cold packs, labeled correctly. I'll post Janoshik certificates in the replies if anyone wants to see them.
Overall: very satisfied. The price scaling with quantity is nice. Not the absolute cheapest but consistency matters more to me.

Those are solid numbers across all three batches. The consistency is what stands out — sub-1% variance between orders is good QC.

That's competitive. I was paying $26/vial from another vendor at similar quantities. Might have to give WWB a try. Did you order through their Telegram or website?

Telegram exclusively. Their handle is in the vendor list. You message them, they send a product catalog PDF, you pick what you want, they give you a crypto address. Pretty standard process for Chinese vendors.
One thing I'll note — their English isn't perfect but they understand product questions well. Response time is usually within 2-6 hours depending on time zone overlap.

Nice review. How are you storing between uses? I'm curious if the 99.4% on order 3 could partly be fresher manufacturing vs the 98.7% on order 2 degrading slightly before you tested.
Also — did Janoshik test for endotoxins or just purity? That's the number I care about more honestly.

Good question. I sent samples to Janoshik within a week of receiving each order, so degradation shouldn't be a factor. Stored lyophilized vials in the fridge at 2-8°C immediately upon arrival.
I only did the standard HPLC purity panel — didn't spring for endotoxin testing ($90 extra per sample). Might do it on my next order though. If someone else has WWB endotoxin results I'd love to see them.
