Zac Perna isn’t just a familiar face in fitness — he’s one of the most relatable and trusted voices in Australia’s health and lifestyle space. His story started from a place many can connect with: wanting to improve his body, his confidence, and his life. What began as a personal journey quickly grew into a passion for helping others do the same. From overcoming his own challenges to stepping on stage and winning his first bodybuilding show, Zac has always led with authenticity, energy, and a no-nonsense approach. For him, transformation isn’t about quick fixes — it’s about showing up, staying consistent, and putting in the smart work that creates lasting results.

See exactly what I take and when to maximize performance, recovery, and results.
I take OxyShred first thing to fire up for the day — it gives me clean energy and gets the engine running whether I'm doing fasted cardio filming or coaching early.
I mix in OxyGreens with my water to get my gut health and immunity sorted straight out the gate. It keeps everything running clean and smooth.
I'll usually stack in Acetyl L-Carnitine too — helps with focus and fat metabolism especially when I'm in a cut or prepping for something big.
Mid-session I sip on Beyond BCAA+EAA to stay locked in and keep performance high especially if the session's long or heavy.
Straight after training I go for ISOPEPT — it's fast-digesting high-quality whey that helps my muscles start recovering immediately. Easy on the stomach and it tastes unreal.
I also throw in Glutamine — it helps with muscle repair and keeps my immune system on point especially when training volume's high.
