Yes, 250 mg of test absolutely "Could" have something to do with it. 250 mg is a cycle, so do that for 10 yrs straight.
Ive read hundreds of bloods (peoples blood work) and some it wont bother, but for many, RBC and Hematocrit can go thru the roof even with real TRT.
Thickens blood, causes clots/blockages, etc. Not everyone responds the same way.
Best of luck to you Henda, you'll bounce back... Stay off Test for a while, recover, get into a bit more cardio (even walking, etc). It can only help.
If feeling like pure shit later, you and your Dr can discuss TRT with close monitoring. (real TRT, even 50 mgs a week, etc) to start...
Cant be too low either, also not good for people.
