It’s extensively tested for heavy metals and banned substances. My personal preference is their pure, unflavored, no dyes or sweeteners, micronized creatine monohydrate * Creatine Ice Cream Recipe Warm 1 pint (473 ml) of Heavy Cream in a pan. While the cream is warm, but not hot, add in 5 egg yolks and mix immediately. You don’t want the yolks to cook. If they do cook, start over (but keep your creamy egg accidents for a snack). Add vanilla, organic liquid stevia, and a pinch of salt to taste. Add four 5 g Scoops of creatine. The recipe makes about 3-4 servings. Obviously, you can double, triple or quadruple as you see fit Here’s where you can get creative. In the batch shown I added Turkish coffee, but you can also add anything you want. Mint, melted chocolate or cocoa powder, berries. Make it your own. Then pile it into an ice cream maker and turn it on until it reaches the desired consistency. Video Description: We’re told muscle loss with age is simple: you get older, you lose muscle — so just lift weights and eat protein. But new research reveals a surprising paradox inside aging muscle. The very pathway that tells your muscles to grow — mTOR — is often more active in older muscle, not less. So why does muscle still shrink? In this video, we break down new findings published in PNAS and explore how chronically elevated mTOR can impair cellular recycling (autophagy), accelerate senescence, and ultimately degrade muscle quality. You’ll see how this paradox actually makes sense — and how exercise uniquely solves it by stimulating growth while restoring cellular renewal. Finally, we cover evidence-based strategies to support healthy muscle aging — including resistance training, creatine, omega-3s, sarcosine, and oleuropein — grounded in current research.
