I didn't feel an effect from the GLP-3 RT or Tesamorelin purchased in early September. It was mailed to me in a standard box without refrigerant, which I've read is completely necessary for this product. Don't think I would recommend this product or company to anybody else. I paid a premium that was not kept on the product side.

Hi Kyle, We’re sorry you were disappointed with your order, and we’d like to clarify the concern about refrigeration. The products you received were supplied in lyophilized (freeze-dried) form. This process removes water to improve stability, allowing peptides to be shipped at ambient temperature. They do not need refrigeration during shipping. That requirement is for peptides already mixed into a solution, which need refrigerated storage. That said, we take your quality concerns seriously. Please contact our support team with your order number so we can review. —Emily, Prism Labs
