WAYYYYYY before ever becoming affiliated with I-Force, I tried halodrol twice at 50mg from two different companies. Both times, literally saw no better results then with a non-hormonal stack. I see no point in running halo at 50, when 10mg of superdrol blows me up a hell of a lot more.
Protodrol at 50mg was a little weak. At 75-100mg, it worked great for lean mass gains. Not as drastic as superdrol, but not as slow as Bold. Gains and effects were somewhere between bold and mdrol, but closer to mdrol's side.
