I called the number and spoke to someone about quantities needed. He walked me through the purchase process and offered some helpful insight into quantities needed. He made sure not to give medical advice but was very thorough and informative. Great experience overall. The peptides take some time to see the benefits. Waiting on results.

Let me start this off by saying I came across this company at the time when there was a scarce amount of bac water and my main company at the time had taken a hit, and wasn't supplying any and it was time to replenish all peps and supplies. Thus I had to find a reputable company, that was located in texas with the chances of me receiving my products in 2-3 days. Which I fell upon Offline peptides from trust pilot. What I can mention that others haven't already mentioned. The customer service is top notch, I've never met another online company that responds as quickly and resolves any issues/problems as promptly as these guys. However if only there wasn't a reason to follow up with customer service in the first place. If only the quality of their products matched the quality of the customer service. The reta is great and solid quality, at first I was sent a 20 mg by mistake when I ordered 30mg. Resolved within 3 days at my door step no problem.Ghk-cu great product no problem there. Tesamorelin however is where the problem occurred repeatedly. We went through a half batch before only having one that was not compromised every vial I was sent was either contaminated/compromised. They had to pull the batch completely and luckily had another batch to pull one from to complete my order which overall process took 2 1/2-3 weeks. If it was only about customer service id give this company 5 stars however its about the product as well. I know they didn't make the product but maybe change wholesalers of your products. For that I give them 3.9 stars Great company. Needs better quality in all their products.

Justin, we genuinely appreciate you taking the time to write this out the way you did. The fulfillment error and the batch issue were both unacceptable and we own that completely. Resolving it quickly does not erase the time and frustration it cost you and we understand that. We have since addressed the quality control concern on our end, raised the standard on what we accept, and made real changes. We appreciate your honesty more than you know and we hope to have the opportunity to earn back your full confidence. The Offline Peptides Team

To know the peptides have been third party verified and you can see the actual certificate is huge to me! I trust what I am getting is legit. Fair prices across the board for all peptides. I trust Offline's product and will be repeat customer.

Randi, putting the actual certificate out there instead of asking people to just take our word for it is the whole point, and keeping prices fair across the board so nobody feels priced out of quality matters just as much to us. Glad both of those landed the way they should and excited to keep earning that repeat business. The Offline Peptides Team
