If you’re still chasing the latest “viral” supplement trend, Arnold Schwarzenegger wants you to stop. For 2026, the legend has partnered with Momentous to launch Arnold’s Stack—a back-to-basics trio that ignores the hype and focuses on the three non-negotiables he’s relied on for decades: Whey Protein Isolate, Creatine, and Vitamin D3.
The stack features grass-fed whey sourced from Europe, packed with enzymes to prevent bloating and speed up muscle repair. You also get Creapure® Creatine, the gold standard for explosive power and—interestingly—brain health. Rounding it out is a daily dose of Vitamin D3 (2000 IU) delivered in organic olive oil for better absorption, ensuring your bones and immune system stay as strong as your deadlift.
The philosophy here is simple:, it’s designed for anyone who wants to train, recover, and actually keep their gains as they age. You can grab the full bundle here, or subscribe to knock 25% off. It’s the ultimate New Year reset for your gym bag—clean, effective, and vetted by the GOAT himself.
