You seem like a pretty smart dude with priorities in the right place. So I’d like to help you. I believe most 20 year olds should not be using gear, it’s more because most 20 year olds are stupid and irresponsible not because of the huge risks they pose. Most importantly before doing anything you have to get bloodwork. The cycle could use some tweaking. First, the test dose is a little low and injections are spaced a little to far apart. That protocol is not far from a trt dose. Instead of 150mgs every 5 days, I would go 200mgs every 3 days. That will keep blood levels more consistent and higher. 400mgs a week is a good starting point for a first time. Also, I would save the hcg for pct not on cycle. In trt hcg is used to keep the testes producing sperm in men that still want to have children. It has no effect on natural testosterone production while on cycle. I don’t think that not having shrunken balls on cycle is a good enough reason to a add another drug to the mix.
