from drrman:
The powders are dissolved per se in the ba and bb you put in the beaker with the powder.
below is the way i prefer to make my injectables as its the most pain free i have found
BA is benzyl alcohol and keeps the oil/hormone sterile, it will kill most bacteria and is required, but it is the reason most injections cause pain. It was formally thought that you needed much higher BA with higher mg/ml ratios, but its not necessary
you can use the 2/20 or 3/17 on damn near anything you want to make...YES, that works the best on most anything. 2%ba and 18%bb, the ba is enough to help dissolve and keep the oil sterile, and the BB will keep it from crashing and make the oil thinner and more easily dispersable in the depot
you can go as high as the following using this
Trenbolone:
Acetate - 150mg/ml
Enanthate - 500mg/ml
Testosterone:
Enanthate - 400mg/ml
Cypionate - 300mg/ml
Propionate - 150mg/ml
Phenylpropionate - 150mg/ml
Boldenone: Undeclynate(equipoise) - 600mg/ml
Nandrolones(decas)
Phenylpropionate - 150mg/ml
Decanoate - 400mg/ml
those are just a few examples, you can also get into blends which many UG labs seem to be doing.
