Since there are many requests to name a specific vendor who is "reliable" (a relative term when speaking of GLP-1 providers who are not selling the presription stuff, I'll do so. Here is my list of semi-recommended vendors. The order they are listed in has nothing to do with which one is better. I'm not including the way overpriced domestic vendors, many of which are quite reliable.
Shanghai Nexa Pharma • aka SPC • aka SNP: A little on the pricy side. Despite the name, you're buying it from a guy who lives in the US. If you're going to skip testing, SNP is a good place to use because SNP arranges and pays for some supposedly independent tests. While I'm not sure how independent those tests truly are, SNP users often regularly test. When there is a problem, Cain fixes the problem. He accepts credit cards. Someone will bring up the fact that when Cain first started he told a million lies. I'm not going to try to defend him on that point; Cain for the most part does not try to defend his past lies.
Shanghai Sigma Audley New Material Technology • aka SSA: Good place. This is the cheapest place on the list. Like most vendors, you are going to need to have your stuff tested, join a group that's testing your batch, or just wait until someone tests. However, relying on other people's test can be bad because your grey top retatrutide may be from a completely separate batch than the other person's grey top retatrutide that was sold 3 days aspart.
Tianjin-Cangtu International • aka TCI (NOT Tianjin FINDER International) • aka HBCangtu. Good place.
Peptide Group Buys (PGB): Even most folks who regularly pay for testing of the GLP-1 drugs they buy don't test when purchasing from PGB. They do true independent testing of what they buy before selling it to you. They're pricier than some of the others, however, you probably don't have to test. You do have to be pretty good with computers and you have to be willing to use crypto to use PGB.
Amo (BFF): There used to be a place called Amo, then BFF, but it keeps getting renamed and they keep losing their website. When they're around, they consistently produce good quality stuff.
This list is, to a large degree copied from Cocodrie's list.
GYC isn't included because they've recently been silent.
Shanghai Wibson Biotechnology Co., Ltd. (WBS) isn't on my list yet. They are new, often have lower prices than SSA, but they are too new for me to recommend. But many people like them.
If I had produced a list 6 months ago, many of the vendors that would have been on that list would not have made the current list. It is common for good vendors to stop being good vendors.
If you make many purchases of GLP-1 drugs from non-prescription sources, you are quitely likely to be scammed at some point. That is the cost of buying research grade peptides.
