alt Hacker News> The real question is: Should you be putting novel, poorly researched and dubiously manufactured substances (which happen to be peptides) in your body via injection?
on one hand: no, absolutely not, hell no.
on the other hand: these people are voluntarily doing human sperimentation. things like this are going to happen anyway so we might as well collect the data (samples, effect etc). it's not much different from the safe needles initiatives.
Except the data is completely useless. Especially given the extremely strong selection biases towards: status/image-obsessed; high-risk; low-intelligence; generally high appetite for a constellation of dubious interventions.
