I've gotten peptides from another company but had I 20% off coupon so I thought I would give Sigma a try. Some issues came up with shipping but Sigma immediately responded to all my questions and made it right. I appreciate a business that takes care of their customers and responds to your inquiries in a timely manner. I did receive the products and they seem to be high quality. I will definitely use Sigma Compounds again, not just because the product is good but the immediate attention they gave me and willingness to make it right.
