Well I'm prescribed 200mg/week test cyp, 1000iu hcg/week, and 1mg adex/week through an out of pocket clinic. That's how much my refills allow me to use. Obviously I utilize the full 200mg, and thanks to PSL I can just use their test and stockpile my Pharmacy test for traveling purposes.
Typically though, I'll just cruise on PSL test E at 250mg/week. I'll even toss in deca at 250mg/week but thats because I have everything dialed in and am proactive with blood work and can maintain such a protocol and stay healthy. AI dose is .5mg adex 2x/week, and HCG is 500iu/week.
For a new guy looking to start trt I'd stay under 200mg/week. Start with no AI to see if you even need one (i do). Use hcg at 500iu/week if you're concerned with fertility and atrophy. Get blood work regularly to make sure your e2 is in check and everything else is healthy. From there you can dial in an AI if needed.
