I don't know. But, I started at 100mgs and was still very low test (E actually went down) Then, moved me to 200 mgs and was getting closer to the top. Finnally he moved me to 240mg and I hit the absolute top and started feeling better. (I shoot 250mg now bc its easier) So, My advice is to get tested!! then tested again to tune in the perfect dosage. (you might find you are healthier and even feel better at a lower dose) Here is a link to show the test my Dr. uses.

HCG is add after you are tuned in. It took me about 3 - 4 months to get tuned in and my balls never shrank. But, adding it 2 days before and the day befor my injection gives my hormone balance more consistancy. And, it makes me feel great!
