ThinkSteroids recommended and they delivered
Saw the 140+ page thread about WWB on ThinkSteroids and decided to give them a try. Ordered a mix of injectable oils and peptides. cavan processed my order within hours of payment. Everything arrived in the UK in 8 days, well-packaged with complete COA documentation. The forum was right, WWB is legit.
★★★★★
Every vial vacuum sealed and cold-packed
The attention to packaging detail from WWB is something I really appreciate. Every peptide vial arrives individually vacuum sealed with cold packs maintaining proper temperature. My latest order of semaglutide and retatrutide was no exception. Paid with LTC and had tracking within hours. This is premium service.
Professional operation from Wuhan
Ordered tirzepatide for our endocrinology research. What impressed me was the professional packaging and the detailed COA included with every vial. Communication via Telegram was prompt. Shipping to Austria took 11 days. This is clearly a legitimate manufacturing operation, not some fly-by-night reseller.
★★★★★
The Prosperity Sale discount stacks perfectly
Timed my large order with the Prosperity Sale and combined it with the crypto discount. Ended up saving about 15% total on a $900 order of mixed peptides and SARMs. The checkout on their website is clean and straightforward. Products arrived in 4 days to Vancouver from the USA warehouse.
Ships to Eastern Europe without problems
Ordered from WWB to Bulgaria which many suppliers won't service. Package arrived in 12 days from China warehouse with no customs issues. Peptides were properly cold-packed and included COA documents. cavan was responsive on Telegram throughout the process. Excellent service for Eastern European customers.
★★★★★
14th order and the consistency never wavers
I've been a loyal WWB customer since 2023 and have placed 14 separate orders. The product quality, shipping speed, and customer service have been consistent across every single order. USA warehouse delivers in 2-3 days to the Midwest. If you're still comparing vendors, just stop and go with WWB.
★★★★★
Excellent customer service via Telegram
Had a question about combining peptides for our research protocol and cavan gave me detailed guidance within an hour. He clearly knows the products inside out. Ordered BPC-157 and it arrived in Germany in 9 days. Professional experience from start to finish. Would recommend to any European researcher.
★★★★★
Ordered the full peptide range, all tested clean
Placed a large order covering BPC-157, TB-500, semaglutide, tirzepatide, GHK-Cu, and retatrutide. Sent samples of each to Janoshik and every single one came back with purity above 98%. That kind of consistency across six different compounds is remarkable. WWB is the real manufacturer, not just a reseller.
★★★★★
Great products, crypto-only is the main downside
The semaglutide and tirzepatide from WWB are genuinely excellent quality. My only real complaint is the crypto-only payment. Had to go through the process of buying ETH just to make my purchase. Once I figured that out, the actual ordering and shipping was smooth. Product quality easily deserves 5 stars.
★★★★★
The COA transparency is unmatched
What sets WWB apart is their transparency. Every product comes with a Janoshik COA and they publish all their test reports on Dropbox for anyone to verify. I've ordered RAD-140, MK-677, and LGD-4033 and every single one matched the stated purity. This is how a manufacturer builds trust.
Fast shipping from China to Japan
Being in Asia means I get incredibly fast shipping from WWB's China warehouse. My order of semaglutide and BPC-157 arrived in just 5 days. Everything was properly cold-packed and the COA documentation was included. Pricing is excellent compared to local Japanese suppliers. Very happy.
Raw testosterone powder was pharmaceutical grade
Ordered 50g of raw testosterone enanthate for our compounding research. The HPLC results from our lab matched the COA that WWB provided exactly. This is genuine pharmaceutical-grade raw material at factory pricing. The 10% bulk discount made it even more economical. Shipping was fast from the USA warehouse.
Ships to New Zealand without issues
Hard to find reliable peptide suppliers that ship to NZ but WWB delivers without any problems. Ordered TB-500 and BPC-157, both arrived in 14 days from China warehouse. Packaging was completely discreet. cavan was helpful through the entire ordering process via Telegram.
★★★★★
Prosperity Sale saved me a ton on bulk order
Placed a $1,200 order during the Prosperity Sale and got the 10% discount plus free shipping. That's a massive saving on top of already factory-direct pricing. Ordered a mix of semaglutide, tirzepatide, and BPC-157. Everything arrived from the USA warehouse in 3 days. Packaging was excellent with cold packs.
Found WWB through PeptideMeter, glad I did
Discovered WWB on the PeptideMeter verified vendor list and took the plunge. Ordered BPC-157 and GHK-Cu for our research work. Communication through Telegram was professional from start to finish. Package arrived in Ireland in about 10 days. Both products came with full COA paperwork. Will definitely order again.
★★★★★
Injectable oils arrived in perfect condition
Ordered Test E and Tren A injectable oils from WWB. Both vials were perfectly sealed, no leaks, correct fill volume. Sent to Janoshik for testing and the concentrations matched exactly what was listed. Shipping to Norway took 14 days with full tracking. WWB is the real deal for injectables.
Switched from my old supplier and never looked back
I was paying nearly double with my previous peptide supplier in Australia. Found WWB through the ThinkSteroids forum and decided to try them. The semaglutide and tirzepatide are both excellent quality verified through Janoshik. Direct from manufacturer pricing really does make a huge difference.
★★★★★
The oral tablets are seriously underrated
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.
GHK-Cu with full COA documentation
Ordered GHK-Cu for our dermatology research project. Each vial came with a COA matching what was stated. Purity was verified through our own testing. Shipping to Sweden was 13 days. Small deduction because the vial labels could be more detailed, but the product itself is excellent.
★★★★★
Retatrutide tested perfect at Janoshik
Sent my retatrutide order to Janoshik and got 98.8% purity results. This is exactly what a direct manufacturer should deliver. USA warehouse had it to me in 3 days in New York. Paid with Solana and the transaction was confirmed in seconds. WWB is my permanent supplier now.
International shipping to Mexico was flawless
Wasn't sure if they shipped to Mexico but cavan confirmed right away. Ordered retatrutide and semaglutide, shipped from China and arrived in 13 days with full tracking. Packaging was discreet and well-insulated. Very impressed with a manufacturer that serves the global market so well.
★★★★★
cavan walked me through the entire process
I'm relatively new to peptide research and had questions about my BPC-157 order. Messaged cavan on Telegram and he responded within the hour with detailed answers about storage and handling. That level of customer support is rare. Product arrived from the USA warehouse in three days and everything has been great.
Bulk ordering for my clinic was seamless
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. This is what top-tier customer service looks like.
★★★★★
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.
First time ordering from China, very impressed
Was hesitant about ordering directly from a Chinese manufacturer but cavan on Telegram was very patient answering all my questions. Ordered BPC-157 and TB-500, paid with USDT. Arrived in Paris in 11 days with full COA documentation. Quality is excellent and prices are significantly lower than European resellers.
★★★★★
Package arrived damaged
My order arrived after about two weeks to Germany but one of the vials was cracked during transit. I reached out on Telegram and while they did eventually offer to reship, it took several days of back and forth to get it sorted. Disappointing first experience.
Crypto discount made this a no-brainer
Ordered semaglutide 10mg vials and paid with Bitcoin for the crypto discount. Ended up saving a decent chunk compared to what I was paying my previous supplier. Delivery to the east coast took four days from the USA warehouse. Already placed my second order.
★★★★★
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.
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. Communication with cavan is always reliable.
Good quality but response time was slow
The semaglutide I ordered was great quality and arrived in good condition. My only issue was that it took about 2 days to get a reply on Telegram when I had a question about my order. Product itself deserves 5 stars but communication could be faster for time-sensitive questions.
★★★★★
350+ compounds and they're all legit
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.
★★★★★
Average experience overall
Ordered MK-677 from WWB. The product itself was fine and appeared to be legitimate quality. Shipping from the USA warehouse was quick at about 4 days. Nothing particularly stood out positively or negatively. It was an ordinary transaction.
Excellent communication via Telegram
Messaged cavan on Telegram with questions about their peptide catalogue and got detailed answers within the hour. Ordered GHK-Cu and BPC-157. Paid with USDT and had tracking within 24 hours. Package arrived in Sweden in 12 days. Very professional operation.
★★★★★
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.
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.
PeptideMeter verified and it shows
Found WWB through the PeptideMeter verified vendor list and I'm glad I did. The TB-500 I ordered was perfectly packaged with COA documentation. Communication with cavan on Telegram was professional and responsive. Will be ordering BPC-157 next month.
★★★★★
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.
★★★★★
Bulk raw materials order was perfect
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.
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.
★★★★★
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.
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.
★★★★★
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.
Crypto payment was smooth and fast
Paid with Bitcoin for my order of RAD-140 and GW-501516. The crypto payment was confirmed within 20 minutes and the order shipped the same day. cavan sent me the tracking number proactively. Arrived in the UK in 9 days. Everything was properly sealed and labelled.
★★★★★
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.
★★★★★
Injectable oils were perfectly dosed
Ordered injectable test E and tren A oils from WWB for our research project. Both came with full COA documentation and the dosing matched exactly when we verified. Shipping to Germany took about 10 days, packaging was discreet and secure. Great quality for the price.
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.
★★★★★
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.
★★★★★
Fast shipping from USA warehouse to Canada
Was pleasantly surprised that WWB has a USA warehouse. My order of semaglutide shipped same day and arrived in Toronto in just 4 days. Paid with USDT and the crypto payment process was straightforward. Will definitely be a repeat customer.
BPC-157 and TB-500 combo arrived perfectly
Ordered the BPC-157 and TB-500 research combo from WWB. Communication through Telegram 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.
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 is always quick to respond.
Have been buying from WWB since 2020. Never disappointed. Always direct factory prices without the middleman markup.
★★★★★
Logistics were smooth. Tracking updated all the way to Australia. No issues with customs at all.
Best factory pricing I have found. Quality is consistent batch to batch and the tracking updates were reliable.
★★★★★
Communication was great. I had questions about the bulk raw powders and they answered within hours. Packaging was highly discreet.
Top tier product quality. Third-party testing checked out perfectly. Delivery to the US took about 8 days, which is standard. Will order again.
