Semaglutide from WWB is the real deal
Fifth order from WWB now and the semaglutide is consistently top quality. Sent my last batch to Janoshik and it came back at 99.1% purity. Shipped from their USA warehouse and arrived in 3 days to Texas. Paid with Bitcoin and the whole process was seamless. Cavan on Telegram is always quick to respond.

BPC-157 and TB-500 combo arrived perfectly
Ordered the BPC-157 and TB-500 research combo from WWB. Communication through Telegram @cavan122 was excellent, he answered all my questions about dosing and storage within minutes. Package arrived to London in about 8 days with proper cold packs. COA was included in the shipment.

Best prices I've found for research peptides
I've compared WWB pricing against at least ten other vendors and they consistently come out cheapest, which makes sense since they're the actual manufacturer. Ordered tirzepatide and MK-677 and both tested perfectly with Janoshik. Shipping to Australia took about 12 days which is standard for international. Already placed my next order.

Janoshik results speak for themselves
I send every order to Janoshik for third-party testing and WWB has never failed me. BPC-157 came back at 98.7% purity, semaglutide at 99.2%. These numbers are as good as or better than vendors charging three times the price. The fact that they're the manufacturer explains the consistency.

Repeat customer - always consistent
This is my fourth order from WWB and the quality has been identical every single time. Tirzepatide 10mg vials, always properly vacuum sealed and stored cold. USA warehouse shipping means I get it in 2-3 days in California. Can't beat that turnaround from a direct manufacturer.

Great product, shipping took a while to Aus
The SARMs I ordered (LGD-4033 and Ostarine) were both excellent quality with COA documentation included. Only minor gripe is that shipping to Australia took about 15 days, which is on the longer side. Product quality itself is easily a 5 though. Will order again with more lead time.

Excellent semaglutide for our research lab
Our lab ordered a bulk batch of semaglutide from WWB and the purity was verified at 99.0% through independent Janoshik testing. The price per vial was significantly lower than what we had been paying previously. Shipping to Italy took 11 days. Very satisfied with this supplier.

BPC-157 healed my research project doubts
Been ordering BPC-157 from WWB for over a year now. Every batch has been consistent and the Janoshik testing always confirms the purity. USA warehouse means fast shipping to Florida and the price point is unbeatable when you're buying direct from the manufacturer. Cavan is great on Telegram too.

Good product but wish they took card payments
The tirzepatide I ordered was excellent quality and arrived well-packaged. My only issue is that they only accept crypto and wire transfer. I had to set up a crypto wallet specifically for this purchase. Product quality is a 5 but the payment options bring it down a star for me.

Ordered 100g of raw testosterone enanthate powder from WWB for our research facility. The COA was provided upfront and matched our own HPLC analysis. Being a direct manufacturer means no middleman markup. Shipping to the Netherlands was about 9 days. Excellent supplier for bulk raw materials.

USA warehouse shipping is a game changer
The fact that WWB stocks their USA warehouse means I can get peptides in 2-3 days instead of waiting two weeks for international shipping. Ordered semaglutide on Monday and had it by Wednesday. Paid with ETH and the discount was nice. This is how all suppliers should operate.

Great quality tirzepatide from a direct source
First time ordering from a Chinese manufacturer directly and I was nervous, but the tirzepatide from WWB was flawless. Janoshik tested at 98.9% purity. The price was about 60% less than what I was paying my reseller. Shipping to Spain took 10 days with tracking updates throughout.

Solid products, packaging could improve slightly
The Ostarine and Cardarine I ordered were both quality products backed by COA documentation. My only feedback is that the packaging was a bit basic compared to some other vendors. Nothing was damaged but it could look more professional. Products themselves are genuinely excellent though.

What impressed me most about WWB is the sheer range of products they manufacture. I've ordered peptides, SARMs, and raw materials over the past year and everything has tested clean with Janoshik. The direct-from-manufacturer pricing is unbeatable. Highly recommend for researchers in Australia.

Shipping took way longer than expected
I ordered from the China warehouse expecting 7-10 days to the US but it ended up taking over three weeks. Tracking was stuck for nearly 10 days with no updates. The product was fine when it finally arrived but the waiting and lack of updates was frustrating.

Reply from Wuhan Wansheng Biotechnology Dec 09, 2025

Hi Frank, we're sorry about the delay with your shipment. International shipping from our China warehouse can occasionally experience customs delays that are outside of our control. For faster delivery in the US, we recommend ordering from our USA warehouse which typically delivers in 2-4 business days. We've also improved our tracking notification system so customers receive more frequent updates. Please reach out to us on Telegram @cavan122 if you need any further assistance.

Two years ordering from WWB, never disappointed
I started ordering from WWB in 2024 and have placed over a dozen orders since. BPC-157, TB-500, semaglutide, injectable oils - everything has been consistently high quality. The fact that they're a direct manufacturer in Wuhan means better prices and better quality control than resellers. Telegram communication with @cavan122 is always reliable.

Hi Lisa, we sincerely apologize for the damaged vial. We have since upgraded our packaging materials for all European shipments to include additional foam inserts and reinforced containers. Your replacement was shipped and we hope the experience with the new order meets your expectations. We take packaging quality very seriously and appreciate your feedback.

Our lab's go-to supplier for two years running
We've been procuring peptides from WWB for our clinical research lab since early 2024. Bulk order discounts are substantial when ordering 50+ vials, and consistency between batches has been excellent. Shipping from China to Canada is reliable at around 10-12 days. Couldn't ask for a better vendor relationship.

I run a wellness clinic in Dubai and needed a dependable supply of semaglutide and tirzepatide. Reached out to Cavan on Telegram and he set me up with recurring bulk pricing at an incredible price point. He even helped coordinate shipping schedules so we never run out of stock.

Everyone talks about WWB's peptides but their oral tablets are just as good. Ordered Ostarine and Cardarine tablets, both dosed accurately and properly pressed. Packaging was professional and discreet. The convenience of pre-dosed tablets versus raw powder is worth it for our research.
