Package of bubble envelope peptides delivered in a hot state without any ice packs. Black box was deeply dented / cracked at one end. Peptide cakes were busted. Contacted the phone number through Whatsapp and the response was completely unprofessional. Answered like a bothered neighbor, not a business. Did not care about any of the concerns or the fact extra was charged for safe delivery, which it was not safely delivered. When I said the communication was terribly unprofessional, the response basically said they should have just waited over the weekend to get back into the office to be professional in their communication. Person admitted they were late to pick up their daughter. Kept trying to defend themselves instead of offering professional customer service.

No concerns for the customer or a remedy to ease the situation. Won't order from again

Disappointed with the experience.

I wanted to give this service a fair chance because the pricing seemed reasonable. After using Retatrutide for two weeks, I experienced no appetite suppression whatsoever following both injections. If you've used Retatrutide, you know the sensations that accompany the dosing, but I didn't even have a dry mouth! I've since discarded these products and returned to my previous provider. I'm relieved to be back on track. I would never consider purchasing from here again.

Overall, a solid experience with this service.

This service is quite commendable overall. They offer fast shipping and provide lab testing information for every batch on their website. The $15 shipping is for second-day air. However, there is a 4% processing fee that applies to the total order. Their prices are generally competitive with other vendors, especially for one product that I found to be the best at $140 for the 30mg bottle I purchased. They also include a QR code on the bottles linking to the specific lab test for the batch you receive. I ordered several products, and while the one did require a higher dose to be effective compared to others I've tried, I found the results satisfactory. Another product performed very well, giving my research subjects plenty of energy, and the third seems promising as well. Overall, they are performing well, but I would appreciate if they tested multiple vials from each batch for purity, especially for that particular product. I'm also interested in the sourcing of their compounds, as I prefer suppliers that utilize American labs due to their higher standards. All in all, a largely positive experience. I also want to acknowledge some individuals who provide great insights on peptides.
