Two weeks into my cycle of mdrol and my joints are killing me. I'm young, 24, with previous cycle experience. I'm in great shape, all I'm taking at the moment is fish oil multi mdrol an other cycle supports. My knees are fucking killing me.
Switch to a higher volume routine in the meantime. Don't push your joints and soft tissues too hard, especially on mdrol where you may be dehydrated (Superdrol is known for this!) or simply gaining insane amounts of strength in a short period of time.
Androbulk, Anavar and Deca** can help on-cycle with joint problems.
