 Rubber baby, now I can't. Aha, I got one person today. So HMB, the metabolite of leucine. Got some amazing science behind it. My HMB is the one I recommend. Like I recommend CreaPure Creatine. I recommend my HMB, not just regular HMB. And this HMB stimulates protein synthesis and reduces muscle breakdown. So it's dual action. Over 30 years of studies with this.
