This is an initial review. I have not used the peptide yet. I did a lot of research between the various peptide suppliers. A lot are cheaper, but want a suspicions payment method(not a credit card) like Bit Coin or Alibaba money xfer, etc. These payment methods do not provide consumer protection. These sites might be ok, but I did not want the risk to save a few bucks. Certified shipped my order in 2 days and it arrived via US post quickly. The product was as described. They actually upgraded the order from 30mg to 40mg because of a stocking issue with 30mg. That is a sign of a quality vendor. I made a second order(because of a deep discount special) and it was same level of service. I'll report back once I use the product. The product was packaged well. I also bought the BAC kit, which was cost effective and had all necessary items to reconstitute and use. Again, signs of a quality vendor. So far so good. I'll update later.
