It’s not Joe Rogan, but his guest with a financial interest in the peptide industry, who characterizes the situation that way.
FDA removed certain peptides from the list of compoundable ingredients because there wasn’t enough strong clinical data indicating they are safe. FDA wasn’t wrong. Most “data” is anecdotal or observational. FDA didn’t ban them. They just said there’s not enough data there to suggest they’re safe and have FDA’s blessing or suggestion that they’re safe.
