Dietary supplements, goopy "meal replacement" stuff, injecting proteins now... Have these people considered this thing called "eating food"?

Peptides in this context are functional not dietary. When you eat protein it gets broken down and rebuilt into numerous proteins or used for energy. In this context they are taking a peptide which is just a short amino acid chain but it has very specific functional characteristics. Normally peptides don't make it past the digestive tract which would ruin their specific functional characteristics so, like insulin which is also a peptide, they must be injected to actually work

  "Work" in what sense? Your body makes these out of the proteins it breaks down in your digestive system.

    In the sense that administration of these peptides means that we want to increase their concentration over endogenous levels in order to have some effect

      Why, though? Sounds like a lot of work for no real reward.

        Why do you think there is no real reward

        Well, what is it supposed to do? How are you supposed to tell if it makes a difference?

        Let's take thymosin beta-4 as an example, it's a protein involved in actin polymerization which is a component of muscle. People use it as a performance enhancer, so theoretically if your ability to recover from high intensity training increases then you can tell it's working. Peptides are no different from other drugs besides the fact that they can be short to long sequences of amino acids https://en.m.wikipedia.org/wiki/Thymosin_beta-4 https://en.m.wikipedia.org/wiki/Thymosin_beta-4 There are a ton of different peptides that do different things so there is no "one thing a peptide is supposed to do"

        Is this something you can actually measure? Or is it just an expensive and complicated source of warm fuzzies?
        kevviiinn 4y ago
        I don't know man can you measure the effects of any other drug? Why do you think these are somehow different? Did you even read the wikipedia article I linked? The peptide I mentioned is banned by the world doping agency, but it's probably because it just gives athletes a warm fuzzy feeling right? At this point your comments seem intentionally disingenuous
