This group has been outstanding. So much great information. Everybody willing to share their experiences, their knowledge and their research freely. I have not seen members attacking other members. Our skipper, Justin has done an amazing job keeping the group clean without a bunch of monsters are scammers or troublemakers coming into the group causing problems. Thank you to everyone in peptide underground.
