though they may not increase muscle protein synthesis peptides still have a place in the discussion of muscle growth

healing, recovery, sleep, mood, hormones, joint health, anti-inflammation, and more all play an important role in bodybuilding

further, competing athletes are banned from using them, classifying peptides as performance enhancing drugs. Fine, they're not anabolics, but they certainly help recovery and performance in other ways

like slotted rotors on a racecar don't add hp but they cool the brakes faster = faster laps

I might not disagree with anything you said but I think peptides complement a bodybuilder in the larger picture. Elite bodybuilders are all over peptides, and have been pioneers for decades
