It took 5 seconds to find because there are 1,000 others recommending the same amount.
Do you have a reference quantifying the estrogen effect of 600 mg of whole fenugreek, for example in terms of equivalent mcg of estradiol?

Yup, it's been up for over a year.

Is this combination a good routine with the right dosage for me?

At 125 pounds?, no, I don't think so.

So would my original plan be good, 
PM, Maca, and flaxseed oil massage?

I didn't see any amounts, however:

PM
Maca
FG
Spearmint
Hops

Those herbs are a good start, from experience (and research) SP and flaxseed inhibits estrogen. For massage use olive oil, coconut oil, or aloe Vera. Though aloe vera (gel) with olive oil is pretty incredible.
