dude eq is painless when injected, secondly you need alot to get good results from it (at least 50mg (more like 100) ed to get the muscles bulging and vains poppin out) i just don't see the point of doing it transderm. if only half to to 3/4 of the product is absorbed into the body. what a waist of money??!!. i don't mean to offend you or anyone else that reads this but whats the point? you could spend the extra money saved on something else.
