Have made several purchases from this company. It was always 100%. I made a bigger order and out of all of my bottles two of them hardened up and would not mixture. I used their antibacterial water as instructed. They are refusing to replace the defective bottles. Would not recommend this company in the future.

Hi Chahira, We take reviews like this very seriously, which is why we thoroughly checked our system before responding. At this time, we have no record of any order, communication, or contact attempt under your name, and the details in your review do not match how our company operates. For clarity, Apex Peptide Supply does not offer “fast” or expedited shipping, and we have no unresolved customer service inquiries—calls, texts, emails, or website messages—matching your description. We have recently encountered multiple cases where customers have mistakenly confused us with another company using a similar name. Based on the information provided, this appears likely to be one of those situations. If you did in fact place an order with Apex Peptide Supply, we are more than willing to investigate and resolve this immediately. Please contact us directly with your order details so we can assist: 📧 [email protected] 📞 505-370-2370 (call or text) We stand by our service and responsiveness, and our existing customer reviews reflect that.
