@thebeautydoctrine: Muscle first 💪 MUSCLE OVER COLLAGEN, Part 3: Leucine + Dileucine We talk constantly about protein for preserving muscle, but one amino acid inside that protein is especially interesting: leucine. Leucine does more than provide building material. It helps activate mTORC1, a major signaling pathway involved in muscle protein synthesis. Now bond two leucine molecules together and you get the peptide dileucine. This is where the research caught my attention. In a randomized human study comparing the same 2 gram amount after resistance exercise, dileucine stimulated muscle protein synthesis approximately 60% more than regular leucine. That's the molecule in MuscleTech Peptide 185. Each serving provides 2 grams of DL185 dileucine, matching the amount studied. The research on dileucine is still emerging, so I'm not putting it in the same evidence category as creatine. And it doesn't replace adequate protein or resistance training. But the early human data are interesting enough that it made my muscle longevity stack. Because my healthy aging strategy is becoming increasingly clear: Build the muscle. Preserve the structure. Support the signals. Collagen matters. But I'm no longer making it the center of the aging conversation. MUSCLE OVER COLLAGEN. #MuscleTech #WomenOver40 #MuscleHealth #HealthyAging #StrengthTraining
