What happens to muscle glue at night after workout and protein?
Casein Ingestion Does Not Increase Muscle Connective Tissue Protein Synthesis Rates

Your muscles have 'glue' (connective tissue) that helps transfer force. This study checked how much of that glue gets rebuilt overnight after a workout and a protein shake before bed.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies

Evidence Score
Participants are randomly assigned to treatment or control groups, minimizing bias. Considered the gold standard for testing whether an intervention causes an effect.

If young guys work out and then drink a protein shake before bed, it doesn’t help their muscles’ connective tissue build more overnight — not any more than just working out alone.
Lifting weights helps your muscles rebuild their internal support structure while you sleep by boosting protein production in the connective tissue inside the muscle.
When you eat protein after working out, your body uses it to help repair and rebuild the tough tissues in your muscles while you sleep — and exercising makes this process work even better.
Working out in the evening helps your body use protein from food more effectively to repair and rebuild muscle overnight—almost 60% better than just resting.
Drinking a protein shake with casein before bed helps your muscles grow and get stronger while you sleep, especially if you're working out.
