Hi there , 1st post . Am 51 & ive started doing my own trt .. 300mg test e spilt into 2 jabs . Am feeling great but am wanting to run some hcg to help my stones out with shirkage. Am happy with the mixing procedure etc, my question is how often shoupd i run it? I have a 5000iu bottle with 1ml sterile water kit . Ive worked out 0.5ml would be 500iu , am guessing i will only get 3 jabs out the kit so it would work out expensive to run all the time, can anyone advise how ofen to run it?
