Hello, I am a Chinese manufacturer of peptide raw materials. Semaglutide is also a popular product of our company. There are also Tirzepatide, Retatrutide, BPC-157, TB-500, AOD-9604, HCG, PT-141, etc. The quality and price of our raw materials are very popular. Perhaps you have a fixed partner, but we still hope that you can allow us to send you a price list so that we can work together.
Best wishes
