Just enough to shut down your natural production. Not a gaining cycle. You might have retained a lot of water if you didnt use an AI.
250 is close to my TRT dose. Muscle tissue is very lean and packing on that many pounds is just not possible with a tiny dose like that for such a short period.
I'm not saying you didnt gain weight, but it most certainly was not all muscle. Not even 10% of your gains.
