Some of these, like Klotho, rely so much on hypothetical benefits that I can see that.
There does seem to be a wave of podcasts and email newsletters starting to hype it up again (from “Hunter Williams” at one end of the spectrum to Dr. David Barzilai (@aging doc on X) at the other end) which makes me think that either they have figured out a source to sell more of it or there is some study/publication about to come out on Klotho.
I believe that the benefits of elevated Klotho are real.
The problem seems to be that exogenous (injected) klotho is so rapidly cleared from the body that it is doubtful it has time to initiate changes. You would need to inject large amounts every day.
The solution seems to be either to work on boosting your own production of klotho, or use a genetic modification to increase expression of klotho. I don’t know of any lab or company offering the latter.
I have Dr Fraser to thank for sharing his pioneering work in klotho.
Actually the short half life of Klotho is immaterial. It is the PF4 activation that occurs immediately after klotho administration that is important. (For cognitive effects) unknown for whether klotho half life is important for the overall reduction in MACE
I think the main reasons many people don’t use Klotho, aside from the fact that it isn’t so well known, is the fact that it’s hard to get hold of it and that it requires injection. Only a very small minority of people ever use things that aren’t approved as supplements or drugs or require injections.
Personally I’ve been aware of klotho being potentially beneficial for aging since long before people started experimented with it. My cautious approach has been to simply try indirectly supporting endogenous Klotho production.
Jay Campbell is selling Alpha Klotho with modifications to extend half life. I doubt it is real or safe and I regard Jay as one of the worst humans in the peptide space. But here is the link for the curious. I would love to know if it can get tested and if anyone can find an Assay for testing it to confirm it is working.
I’d normally never jump on anything almost no one is doing, but I felt comfortable trying klotho simply I was advised by a smart doc and Peter Attia and Tim Ferris have said they are about to be guinea pigs in a trial (which to me says they already take it but who knows)
I am curious about so many peptides, but I have only experimented with NAD, glp1, and klotho. I am ordering SS-31 now (felt comfortable after rapadmin met the researcher), and I might add TA-1 to my order to have on hand incase I get sick (really, adding TA-1 it all about getting free shipping because I’m a sucker for that, so I’m still googling to see if there are any potential downsides).
@touringsedan there is a klotho test one can take. If I recall, it might be $300 or so? (Grain of salt on that $) . I definitely don’t have the stomach to test out a new form on myself.
