@PaulB Thanks for sharing that I haven't heard of Dr Ruscio, but that doesn't necessarily mean much (I'm more up-to-speed with people over here than in the US). However, I would caution against undertaking any treatment based on a podcast (or, usually, any single source) alone. From a very quick glance, the podcast's results were based on one study (not of people with ME/CFS) and Dr Ruscio's personal experience (nice, but far too small a sample size even if he was rigorously scientific in his trialling, which the podcast doesn't suggest he was, and would be very difficult for an individual to do in any event, with placebo effects and other factors muddying the data).
I also noticed Dr Ruscio had some less-creditable topics covered on his sight, like the Gupta method, which casts some doubt on his potential reliability as a source of information.
It's well worth looking into, but rather than start a conversation on peptides in the "recent media" thread, it might be better with a thread of its own?
