Peptide supplements are flooding the internet with promises about weight loss and joint repair. A physician says the science behind almost all of them stops at a Petri dish.

Dr. Mitch Shulman says the gold standard for knowing whether anything works is a double-blind placebo-controlled randomized trial, and none of the substances being touted online have been through that process. What gets sold instead is anecdotal evidence, the most biased form of data there is.

Beyond whether these compounds work, Shulman raises the question of what is actually in them. Heavy metal contamination, unknown sterility, and unverified manufacturing are all possible when you bypass Health Canada approval.
