BC in bb.com has recommende: In a diol/diol stack nothing beats 5-diol, because though only moderately effective in conversion, prior to it it has the capability of upgrading receptors ensuring a greater conversion from the Nor-diol, enhancing its effects. The downside to a ski-slope is that mass accrual near the end of the stack is compromised in an attempt to maintain earlier gains.
IS this true?thanksriskybizz007
