Here's my experience so far.
I reached out to Core Peptides to ask about pricing and fees, and they responded quickly. They explained how the ordering process works and answered my questions. Shortly after, someone pretending to be core Peptides messaged me, but it turned out to be a fake account.
I decided to place a small test order. I paid with crypto (which I normally don't prefer) and sent my payment confirmation on Sunday. They replied almost immediately, thanked me, and said I'd receive my tracking number on Monday or Tuesday.
Today, they updated me and let me know the tracking number will be sent on Tuesday. They also shared a screenshot showing communication with the warehouse.
I've had a few people message me saying it might be a scam, but so far my experience with the communication and ordering process has been positive. I'll continue posting updates until my order arrives. If you have any questions about my experience so far, feel free to send me a DM.
