For the oil its extremely important to use a fast absorbing oil. So stuff like GSO is best avoided for injectable dbol/anadrol.
100 ml recipe
5 gms of powder
2 mls of BA (2%)
20mls of BB (20%)
8mls of Guiacol (11%)
20mls of castor oil (30%)
45.75mls of GSO
That recipe is not right.
It works I've used it but scaled the recipe up to 250g dianabol
Why not use 100% Mig840 and call it good? No need to mix castor and GSO then.
I got 50mg/ml to hold fine at 2 20 in safflower
