So HCG will help your body upregualte natural test production. Some say it is a fat loss drug. Thats a marketing scam/diet plan that is coupled with a very low cal diet. I think there are better options than HCG, like actually using test at a TRT dose but if you want to try this, I would do 250iu every 3 days along with .5mg adex on shot days. If you want to increase, you could try 500iu if effect was not strong enough. You could do this long term for several months
