I've seen that some of the BDs products have left the R mark
behind, ex: Decabol R = Decabol 250, Trinabol R= Tri-Trenabol 150
I guess most of the products that changed names which hadn't
strenght at the end get the R mark supressed after the change.
I'm not sure about Primobol but as far as I know they have the
R mark after Primobol. Sometimes they change in a sudden to
play tricks on the fakers?!? Shot a PM to Retabolil2, he might
know the answer 100%, bro!
