It depends on how many mg's of peptide you have per vial. If I were using a 5mg vial of GHRP, I would want to use more than 1ml bac. I use 2.5ml. This way, the volume of water is large enough to get a good accurate dose. As for AAS and peptides, most certainly. Any of these peptides are only going to work better when using an anabolic.
