I’ve ordered from Peptide Source Canada…
I’ve ordered from Peptide Source Canada before and had good results — particularly with their testosterone gel and injectable cypionate, so I had confidence in the company. Unfortunately, this time around was a letdown.I ordered two vials of Retatrutide, and neither vial worked. No appetite suppression, no side effects, absolutely no response. I suspect the issue was shipping — the package was sent without cold packing during an Ontario heat wave, with temperatures hitting over 34°C. Peptides are sensitive, and this kind of exposure likely degraded the product.I reached out to customer service and spoke with Noah, who responded quickly and professionally. He asked for photos (which I sent), and then suggested I try Mounjaro instead, as it apparently holds up better in heat. That’s fine — but what about the two dead vials of Retatrutide?I asked if future orders could be cold packed, and they said yes, and even offered to do it free of charge. That’s appreciated — but honestly, it should have been standard procedure in the first place, especially in summer, and especially when shipping peptides within Ontario during a heatwave.I'm giving 3 stars, not 1, because:They’ve been solid in the past.Customer service was responsive and respectful.This may be a one-off.But I removed:1 star for shipping peptides without cold protection, despite known heat conditions.1 star because they didn’t offer a replacement, refund, or even a discount on the next order to make up for the $360 loss. I even followed up asking what to do with the remaining useless vial — no response.Overall, I’m disappointed and will be switching to Canadian Made Labs for Retatrutide, which I hear just got stock in. Peptide Source has potential, and some of their products are clearly good (hence all the 5-star reviews), but I can’t afford another expensive letdown like this.
