yes the synovex S is for steer, while the H is for heifers and C is for calves. i've read a site that mentioned that the H had estrogen in it, but did not specify what the S or C had in the drug. I figured that the S would contain less estrogen since it is used specifically for steer.
Does the conversion eliminate the estrogen?
Also, I know it is legal to purchase the tren, but do the same rules apply for the syno?
