Like many others, I was hesitant to order peptides on-line. After much research of many companies, looking at their sites and reading many reviews on Trustpilot, I decided to take a chance on Certified Peptides. The process of ordering was seamless, the prices were very competitive and shipping was quick. Got the product in excellent condition. I have not yet started research with the peptides, but based on reviews I'm sure it will be safe and effective. I'll write another review after some research.
