Due to toxicity, I was thinking of only running the tamoxifen at 30/30/20/10, following a Superdrol 20/20/30....
Any comments?

That is exactly what I am doing man. Just got off of a superdrol cycle. Goin with 2 Ml. per day ( one in the A.M./ one in the P.M.) for two weeks, then 1 Ml the 3rd week, then half of a Ml. the last week. I'm also taking retain 3 times per day to reduce the cortisol, and i'm also taking the old formulated axis Ht for the natural test.
Yeah, I know this other guy that actually told me to take it like how we are. I honestly could not tell you why people are using the 40/40/20/20 method. I'm not saying they are wrong, I just think it helps to taper it off a little bit more. Anyone else have anymore reasons or suggestions. I must say though, my PCT so far is really good. I have ectually gained weight since I got off of the SD. My lethargy is almost gone and I still have the same intensity in the gym. I must admit though, my joints are a little sore.
You should ask Dr. John. I remember his posting on another board that he moderated that it could be done something like 40-20-10-5.
