What does it actually take to build a supplement line worthy of a 60-year legacy?

Kenny Carter, Director of Product Innovation at Gold's Gym, breaks down the full

formulation philosophy behind the Gold's Gym supplement line — from why citrulline is dosed at 8g, to why creatine belongs in a gummy instead of a pre-workout, to the role AstraGin® plays in making every other ingredient work harder.

In this episode, Kenny covers:

→ The "gold, silver, bronze" dosing framework — and what most brands get wrong

→ Why AstraGin® is in the pre-workout (and why most brands skip gut health entirely)

→ The creatine gummy: why it exists, and the pH-stable pectin process behind it

→ Natural caffeine vs. synthetic — and what it means for how you feel mid-workout

→ The "less is more" philosophy for younger athletes

→ Where the Gold's Gym supplement line is headed: RTDs, protein snacks, hydration

→ What it was like to walk into the Mecca for the first time — and never leave

Kenny trained at Gold's Gym Venice Beach for a decade before moving into product development. He's been formulating for science-first sports nutrition brands ever since. This conversation goes deep on what separates ingredients that belong on a label from ones that actually move the needle.
