The weight for deca is still .75mg/ml displacement. To use 10 gms it would be 7.5ml in liquid form (I put my bag on a hot pad and put it in the oven at 170 degrees until it melts. Then you can draw it into an 18ga syringe. I use 5% BA and 10% BB so it would figure out to 7.5ml of Deca, 26.5ml of oil, 2ml of BA and 4ml BB. That would make approximately 40ml of gear. Just made 80ml of 300mg deca last night.
