Shipped to me in an envelope and product was warm to the touch, possibly degraded. Sent a support ticket with no response for over a week. Update* Sent a ticket again and got a prompt response and resolution. They say they will heed the requests with shipping moving forward so I look forward to that.

Fast shipping. Trustworthy product. First time purchasing peptides and highly surprised by the almost instant and noticeable results. Will be placing more orders. Highly recommend!! Done my research on this company before ordering anything. Don't hesitate to buy with full confidence.
