Sex hormone-binding globulin (SHBG) is thought to mainly function as a transporter and reservoir for the estradiol and testosterone sex hormones. However it has also been demonstrated that SHBG can bind to a cell surface receptor (SHBG-R). The SHBG-R has not been completely characterized. A subset of steroids are able to bind to the SHBG/SHBG-R complex resulting in an activation of adenylyl cyclase and synthesis of the cAMP second messenger.  Hence the SHBG/SHBG-R complex appears to act as a transmembrane steroid receptor that is capable of transmitting signals to the interior of cells.
Im over 50 in perfect health, and workout daily, and lift 3 times a week . I have gone from 209 to 186 in 4 months, and am very happy. I would like to continue to lose a few more lbs but also want to bulk up a bit more while I lift. is it possible to do both?
tell me what product might do this for me or any combo of products,
should i lose the weight I want first, than concentrate on bulking up after. I realise putting on muscle will add to my weight. unfortunately I belong to a gym where the trainers eat natural and sing kumbaya all day, so i have nobody to ask .
