Recently from eBay I found there were testosterone booster for sale which has the same functions as protein powder ( maybe better) . I am wondering if it is saft to take it and help you build and keep the muscles. Does anyone know if it comes with side effects. Also I found it says that it would increase sex drive, what would happen for a normal man after taking?

There are over 130 natural testosterone boosters on the market, Androstenedrone is banned from the US. Andro shock is not for anyone under 21, or with prostrate disease or on any medication. Testo Boost contains some natural ingredients. Porhormones were banned here in the US in 2004, these are legal, ZMA, Tribulus terrestris, DHEA, EPH/DHA, and estrogen blockers for instance. If they have been approved they are trusted as safe. Look into what you want to buy and look into the ingredients, see if any are unsafe or unnecessary, this is the best advice I can give you.

Firstly testosterone boosters do not have the same function as protein powder. If you would like to gain lean muscle you need 1.5 to 2.0 grams of protein per pound bodyweight. Protein is the best supplement to take. Now testosterone boosters have the primary function as anabolic steroids being that they increase testosterone. Obviously and increase in Testosterone would mean increase muscle mass, eventual impotence as sperm production shuts down plus you would have severe mood swings. If you need to raise your sexual drive consult a qualified physician.
