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.


The Legend Himself

Widely known as one of the best to ever step on the stage, Samir Bannout participated in more than 50 competitions & famously lifted the 1983 Mr. Olympia trophy.

Renowned for his posing & his incredibly developed lower back, which was immortalized as the “Lebanese Cedar'', Samir was inducted into the IFBB Hall of Fame in 2002. 

During his competition preps, Samir religiously consumed the two formulations we’ve modernized & reincarnated today under the Samir Bannout Signature Series: REPLICA GH (growth formula) & LAVA 196 (fat burner). 

This is your chance to experience greatness at its finest!
