individual response to exo test is completely different.Test is fake. For me 200mg of test cyp shot twice per week, same as you, blood draw on the day I`m due for a shot, my total T is 1200 (range is 300-900). Impossible 250mg sust and your test level is mid range.
one have a conv factor of 3 (exo in mg to total t), some have a factor of 7
