Referring to the original post.
The problem with the protocol , and the article attatched, is the implication that these substances have been studied in humans, are safe, and the effects are known, and beneficial. Mostly this is not actually true. In general, the effects of the substances in humans individually are either not known at all, as for Mots c , or not well understood , or not very effective. Combined the effects are completely unknown, and have never been tested in animals or humans.
Many of the references are to something that is not a peer reviewed journal, the international peptide society, I tried to look it up to get a better idea of what it was but their website did not work. But mixing up genuine scientific references to animal studies with non scientific references is at best misleading.
SS-31 or Elamipretide has had human trials, so is known to be safe. Apart from treatment for Barth's syndrome, a genetic mitochondrial disorder, which was successful, the results of the human trials were generally disappointing, failed to meet their end points, and its use for more generalised purposes such as heart failure have been abandoned.
Mots c sounds amazing from animal studies, but has not been tested in humans. It is present naturally in the body so that gives it a bit of a safety factor, but the lack of any testing in humans means it effects in humans are currently completely unknown. There is definite interest from the drug companies in it and modifications to the peptide have been made and tested, mainly so it can be patented, and further research will happen.
There have been quite a few trials of various compounds to increase cellular NAD+, mainly NMN and N Riboside. They showed great promise in animal studies, and it is an important biological chemical, the question is - has it been proved that supplementation has beneficial effects in general or on specific disease states in humans? It has been studied enough to know that it is safe but effectiveness is much more questionable. There are lots of small studies so finding one that shows a benefit is easy, but in general unless enormous very expensive studies are done ( which is not going to happen unless it can be patented ) the easiest way to asses the research is a meta analysis that adds them all together and there are quite a few of them. For example - DOI: 10.1055/a-2382-6829
It's conclusions were pretty underwhelming
"Supplementation with NAD + precursors reduced plasma levels of total cholesterol and triglycerides in volunteers, but the intervention did not significantly affect the other outcomes analyzed *. Three of the included articles presented a high risk of bias. The quality of evidence varied between very low and low due to the risk of bias, imprecision, and indirectness. The number of participants in outcomes other than lipidemia is still generally tiny; therefore, more clinical trials evaluating these parameters will increase the quality of the evidence."
*outcomes tested were
Fasting blood glucose. Fasting blood insulin. Glycated hemoglobin.
HOMA index. Systolic blood pressure. Diastolic blood pressure. Body weight.
Cholesterolemia. Plasma LDL cholesterol levels. Plasma HDL cholesterol levels. Triglyceridemia.
This does not mean that these substances alone or together might not have benefits, they might but it is not known. My objection is that information presented in the protocol and the accompanying article very strongly imply that the science of this recommendation is established fact, it is not. I would guess no reputable clinicians ( which does not include celebrity doctors or similar who sadly seem more interested in making money than providing sound advice ) would recommend mots c or ss-31 on the basis of current available evidence. NAD+ therapies are almost certainly safe, but there is a serious lack of evidence that they work in humans, except for low quality evidence they lower lipid levels and statins are much more effective at lowering blood lipids.
