Ok there is a lot of newbies and even some who dont really know what is best and the effects it has on you in way of aromatase inhibitors (pcts and the like) so I am staying up late to help you guys out a bit. I hope this helps its an accumalative of many different facts all put together for you here.
Products /aromatase inhibition/risudual aromatase%
formestance(4-androstenoldion) /91.6/8.1%
aromasin(exemestance)/97.9/2.1%
cytradren (aminoglutethimide)/90.6/9.4%
arimidex
(amastrozole)/96.7/3.1%
femera(letrozole)/98.7/1.3%
Produc/effect/percentage
formestance(4-androstenoldion) /increases IGF-1/26%
femera(letrozole)/increases IGF-1/24%
aromasin(exemestance)/increases IGF-1/28%
arimidex
(amastrozole)/decreases IGF-1/18%
nolvadex(tamoxifen citrate)/decreases IGF-1/23.5%
faslodex(fulvestrant)/decreases IGF-1/70%
cytradren (aminoglutethimide)/increases IGF-1/27%
I prefer formestane there are many facts about this that i will post later but above should help in you to decide whats best for you and what effects it will have.
obviously if IGF levels decrease so does packing on weight and the amount of lean tissue lost during a calorie restricted periods as well.
Aromatase inhibitors decrease the amount of estrogen/estradiol and etrogen receptor antagonists to keep out of the specific pituitary receptors.
the use of certain inhibitors can affect the IGF-1 production and receptors our tisues posses.
Hope this helps bro's.
