Yeah, that does seem like a lot of 4-AD. Being that you can't easily find it anymore and the risks of buying even if you could, I'd be conserving it by doing a transdermal as the other guy said.
Just buy a
Dermabolics transport matrix in the 8 oz. size and add the appropriate amount of
4-AD powder and you'll have enough for a few cycles if you follow the dosage recommended on the old
4derm bottles.
That was 5 sprays for 200 mg. of 4-AD. If you dosed it 2x per day, 12 hrs apart, as the bottle recommended, you could make you supply last quite a while, if you have as much as you seem to, with your proposed dosage.
Whenever I ran
1-AD, i stuck to the 300 mg. per day that the label recommended. That was pretty effective w/ the 4-AD, so I don't know if I'd want to triple up on that dosage, unless I had lots of ph experience.
