Primo is good, problem is getting real stuff (yes, I know it is posible, but not everyone takes the time to find GOOD sources).
Test Prop also isn't bad. Keep the dose low and constant. Watch for sides carefully. It clears the body quickly.
Nandrolone Phenlypropinate also can be a good choice. Again, keep dose low and constant. It also clears the body fast.
Both Test Prop and NPP can bring on oily skin, acne and raspy voice pretty easily. The acne can persist even years after you get off the substance. Voice change is often permanent if you don't catch it quickly and stop/lower the dose.
