If your just trying to make injectable dianabol, then yes the testosterone propionate recipe works perfectly. No need to add in anything else. Simply use Benzyl alcohol and benzyl benzoate, along with grapeseed oil, or even mct oil.
I forget the exact recipe but its in the sticky thread we have here in this forum, but its really easy when done properly:
Example 10 grams dbol powder weighed out into a 100ml vial, then add your BA and BB , and let it sit over night, shaking it every so often until it fully dissolves, if your in a rush, then you can heat it up in hot water or over the stove until the powder is fully dissolved into the BA and BB nice and clear.
Then you add in the oil, Some guys like to heat the oil prior to adding it to the dissolved powder ba bb solution, but it isnt really needed if your powder fully dissolved in the Benzyl's
For this 10 grams powder of dbol, you can make it painless injectable at 3ml BA and 10-15 ml BB
FACT!
