Should You Buy It?

Our expert verdict

Life Extension Creatine Capsules earn a well-deserved 4.5/5 rating, blending proven science, user acclaim (74% 5-stars), and premium purity. It excels for strength, endurance, and recovery—delivering real ATP boosts without hype. At historical $20-25 pricing, value shines against pricier rivals like Thorne.

However, current unavailability is a hurdle; monitor restocks or pivot to NOW Sports capsules. No major dealbreakers beyond minor GI risks (3%)—far outweighed by benefits. Perfect for dedicated athletes, but casual users might prefer cheaper powders.

Buy if capsules suit you and purity matters—stock up on restock for rugby seasons or bulking phases. Skip if budget-tight or powder-okay; you'll still build muscle effectively elsewhere.
