Dougal, You genuinely have the wrong business. I can assure 100% you did not order from www.peakpeptides.shop. You have us mistaken for Peaksupplements in AU We do not ship to Australia we are based and ship only in the USA 1. We do not respond via WhatsApp 2. We 100% take care of refunds promptly 3. We have zero order history with you Kindly delete this review

I’ve had a really positive experience with Peak Peptides. The ordering process was smooth, shipping was fast, and everything arrived well-packaged and clearly labeled. It’s always a good sign when a company pays attention to those details. What stood out most to me was the consistency and quality. Everything felt reliable, and I didn’t run into any of the issues you sometimes see with lesser known sources. Their customer service was also responsive and helpful when I had a question, which goes a long way. Overall, Peak Peptides has been solid across the board, and I’d feel comfortable ordering from them again.
