Old School Labs x Samir Bannout

We’ve joined forces with IFBB Hall of Famer and OSL Ambassador Samir Bannout, one of the greatest bodybuilders to ever live, to bring back & modernize two iconic formulas that he's credited for his historic 1983 Mr. Olympia win. The results from these two products vastly exceeded our expectations. Wait till you try them.

OSL is proud to announce the launch of the pro-grade Samir Bannout Signature Series.
