I tend to just run it in intervals throughout the year. Can't be bothered injecting it every 4 days or so all the time. I will do 300-700IU every 4 days for 16-20 days usually. Or sometimes just do 500-700IU weekly. I don't like doing high doses as most times I have it has effected me in a negative way (poor erections and libido issues etc). Those negatives only last a day so nothing major. If I take 500IU well I will just say it is the complete opposite to when I do larger doses
I like to get 2500IU amps. That way I can just do 500IU over 5 injections. Therefore potency issues don't come about (keeping it long times).
I run HCG 250iu every four days with great results but you have to be vary carfull about spikeing your estrogen i recoumend atleast .50mg ed Adex if you are runing test and HCG.
I like using 500iu twice per week throughout the cycle. For a while I was using higher dosages but only for a week out of every 6. I find that using it throughout helps not only keep the boys plump but also keeps me feeling a little better mentally (less drained) for some reason.
