I'm sure he got into everything , Kevin was a little different and simliar to older 70's bber era he did the whole "blast" phase and took everything under the sun and when he wasn't competing most likely "cruise " phase with moderate dosages to keep an athletic look until closer to competition. If you watch one of his battle for the Olympia vid in 02 u see in July he looks around 210/215, then goes to sept/oct and he's around 250+ 5% or lower.
While guys like Ronnie and jay are on I'm pretty sure high dosages of everything year round
