The more androgens you have, the easier fat loss is. This is why tren is so powerful for fat loss.
A lot of the time, when I go on higher dose test, I don't actually gain a lot of body weight, but my bf composition changes, in that I gain muscle & lose fat concurrently. I LOVE test. It's a miracle drug & you just feel great on it, as opposed to tren, which works, but is no fun to be on.
