Thats what I thought doc? I thought that the methylated or alkylated drug was done so it would survive "first pass" and have some biological activity, making it harder on the liver but needed to acheive a therapeutic seum level. whereas the injectable form does not need to survive first pass and thats why they are not 17aa? am I right in my assumption? If so, you really wouldnt need liver protection from IM winny.
