"The Role of HCG in Post-Cycle Therapy (PCT) and Fertility"

HCG.
how do you work out appropriate dosing for using this compound to stimulate the testes to produce testosterone?

can HCG used during cycle contribute towards stopping the testes from shutting down? Or keep the testes stimulated?

HCG can help stimulate testosterone production and prevent testicular shutdown during a cycle. A typical dose is 500-1000 IU every 3-4 days. It helps, but PCT is still needed after the cycle.

How long do you run it?

The duration depends on the individual and the cycle used. HCG is commonly run either during the cycle or for a short period before PCT.

Keep those boys in the game by pinning 250–500 IU twice a week during your cycle; it mimics LH to keep the factory running so you don't shut down or shrink, bro.

Those are really bad advices. I am a 43 year old man and I am on HCG, HMG and Clomid. (1) All depends upon your blood work. Get your FSH, LH, Total Testosterone, Free testosterone, Oestradiol and Prolactin levels tested (2) Consult an endocrinologist . Even an online one in another country where you can afford (as long as they are a real doc). Given them your blood work and they will give you a dose. Your dosage can be as high as 5000IU per week for HCG and 750 for HMG....or you might not even need it. Couple of weeks of Clomid just might do the trick. As a reference my FSH levels were <0.2 and LH levels were <0.1 and Total testosterone 0.2....My body wasnt making them at all. 1K IU wouldn't have moved a needle in a year.... Make informed decisions based on your blood work. Finally even when you are on, my advice is to get blood work done ever 1.5 - 2 weeks. In UK you can just ask you GP, they should be able to run these without a fuss and single penny... Answering How long do you run it? These are meant for fertility, your Endocrinologist will tell you a check point. Final termination of cycle should be determined by a Sperm Test. If Sperm test contains healthy sperms...you are good.

You are absolutely right that blood work and professional medical oversight are the only safe ways to manage HCG, HMG, and Clomid, as dosages must be tailored to specific FSH, LH, and fertility markers.
