I'll give you my experience!!

I was 20 years old when I first cycled and did 3 that year I believe...

I did 2-3 cycles a year till around 24

Than @ 25 I would sleep like no tomorrow 10-14 hours a day, losing weight losing muscle, and fatigued all day long

@26 was diagnosed with Low test, doctor made me wait another year till I got on trt

Then it took a few years to get my hormone replacement therapy in check..

If I could go back I would, I am now 32 and do 2 injections a week to just feel normal!!
