I shouldn't respond to your question, Not, because I'm so new to this forum, but...
From reading extensively from this forum, I came away with the impression that a dosage under 1000 mg daily would not likely lead to breast growth. I recall no instances of breast growth on such low dosages of PM alone. It might have other beneficial effects though.
The Ainterol R1 dosage for women is not more than 1000 mg/day. For men, whose bodies are dominated by testosterone, it's hard to imagine anything less having any effect, although many take low doses to maintain breast growth already achieved.
Better answers are on the way, I'm sure.
