Wow, what a cycle!
I have heard of people using 3000IU of HCG a week because they wanted to have a baby on cycle! One thing that makes the test taper look good for you is that you have 3-4 weeks instead of the standard 2 between HCG and PCT in which you re sensitize yourself to LH. A lot of people do 'blasts' in their last two weeks using it.
I think you should always run a SERM just in case:
Bill Roberts wrote: It[Masteron] is I think very unlikely to be a selective estrogen receptor modulator but it likely has some anti-aromatase activity and may have some direct estrogen receptor antagonist activity. But for example -- and going for a more extreme example than necessary -- a gyno-sensitive person should not assume that he could take 1000 mg/week of testosterone ester without a SERM or anti-aromatase in the expectation that 200 mg/week of Masteron would cover him. I wouldn't expect it to do so.
It seems that Masteron works more like an AI than a SERM. You are gyno-sensitive (prolactin issues from GH), and you recover slowly. On the other hand, your Masteron is equal to your prop dosage so it might work fine!
Prisoner did say his libido is better when he replaces the SERM with Masteron. Ask some more people with experience about your particular situation
This does suppress your natural test longer but the idea is the test taper and the effectiveness of the cycle. What's going to be worse, feeling pressure to repeat your first cycle proposition with insufficient recovery time because you didn't make the gains you wanted on it, or running a longer cycle that you are comfortable taking more time to recover from because it actually worked?
Your recovery time may be faster or slower than it would be with your first proposal but you will surely gain more on this cycle AND I expect you will be taking more time off.
