You're right and its always better to be safe rather than sorry but hunk about it like this: at 100mg EOD it averages out to 350mg per wk. testosterone replacement therapy (TRT) doses are usually 100-250mg per week. At 125mg EOD it comes out to 437.5mg/wk. 437.5mg is much further above the testosterone replacement therapy (TRT) typical range but still a very light cycle. On my first I went with ~625mg/wk and results were great and I didn't BLOW up like crazy which is what I wanted. I think if you want to go easy your first cycle do no less than 400mg/wk and up to even 600mg a week would be fine.
125mg EOD is much better than what you originally proposed.
Advice taken (Y) makes sense. how were you're results on your first cycle just out of curiosity? test only? and for how long?
