This is good info and I'd like to add that I bet at some point the body's ability to convert these PH's to desired androgens will become a factor too. Expensiveness aside, I think it would be hard to get enough 4-Andro to be converted to test to make a equalivent cycle to that of pinning test. Maybe even with 4-AD this could become a problem
For what it's worth, I've never heard of anyone doing a 4-AD or 4-Andro solo cycle and have great gains. So I personally think these are decent base products for other anabolics, as Whisky said. I consider the 4-AD to be a base product too, although have never used myself.
What comes to dosing, Whisky gave good theoretical stats and guidelines. Based on what I've heard, people seem to dose between 3 to 6 caps of Androtest a day, which will yield 375 - 750 mg of Cyclodextrin 4-AD complex. How much of that is actual 4-AD, I don't know, but that seems to be the preferred dosing range.
