Old thread I know, but if you're like me and hover threads on these imaginative questions I'll spare your curiosity with some math and logic backed by broscience to give you guys a number to go off of.. Since no one is able to produce one it seems. So being that 4-DHEA can either convert to 4-androstenediol or it's estrogen converting counter part or just end up not being utilized by the body at all we'll go ahead and say that the conversion rate to 4-androstenediol is ~33%..Assuming you've got absorption peaked as well if not try some DHB or other absorption enhancers! Take some E Blockers to assist in prevention of E conversion.. Now according to 4-androstenediol Lore, conversion to Test is ~15%.. So we take say 2g/2000mg of 4-DHEA x 33% = 660mg of 4-androstenediol.. 660mg of 4-androstenediol x 15% = 99mg of Test.. ~100mg x 7 days = 700mg.. This is without calculating half lives and such, which is huge for these equations but like I said, this is just to give those with no idea where to start and require a digit of sorts to set up their cycle. If you want a range, chop that 700mg in half and now you've got somewhat of an idea how much Test you'll be taking 350mg - 700mg. I hope this helps
