meaning what ?
meaning all steroids fight for the same receptors.
which in theory, would mean all you really need to grow is testosterone at 3500mg/wk (the generally accepted estimate at weekly mg amount to 'saturate' the AR's).... or methyltrienolone at 1-2mg/day to do the same. (as well as another 'rare' drug I forget the name of that has incredibly high affinity to the AR)
but in practice, we know that there's more to 'growing' than just saturating the bodys AR, as some drugs have poor affinity to AR, yet exhibit anabolic/androgenic activity outside the cell and AR (anadrol is the most common drug used in that example, but there's others).
look at what drugs and what amounts the 'pros' and other 'big buys' are using, it's all the same, plus or minus a gram or two (which after 4-5g/wk, an extra gram or two doesn't make much difference). you're looking at 3-4g test plus 1-1.5g orals plus another 1.5-2g injectable. (only talking AAS here, not other stuff). 3-4g of test should be plenty to 'saturate' the body's androgen-recptors, plus the orals to do what they do, plus the other inj's to do what they do.
if the 'pros' (I hate using "pro's" as a generic term, like they're some special breed... there's guy's who look like or have genetics of "pro's" in every gym who use the same doses, yet never care about getting onstage) are using 3-4g test plus 2-3g other stuff, why on earth are some ppl on these message boards preaching that all you need is 250mg test plus a gram or two of other stuff?? you think the "pro's" are the idiots who haven't figured it out? or are the msg board guru's preaching low test/high anabolics the ones who haven't figured it out yet? (usually the guys who've never coached anybody but themselves, and have never opened a textbook or even see an abstract on PubMed).
all side effects are manageable. you don't like the bloat? use the proper dose of anti-aromatase or some nolva. (proviron and masteron are not anti-aromatase, I don't give a fuck what 'gh15' says).
btw, adex/asin aren't nearly as effective in men as they are in women. something like 30% less effective at least.
