The UK seems to be wrestling with how to deal with online "Research Use Only" (RUO) peptide vendors, saying, "They put 'research use only' or 'not for human consumption' on the packaging. And this seemingly evades some of the regulations that we have because you're not allowed to sell them as medicines, but if you state it's a research chemical, then the MHRA is going to have a much harder time bringing an enforcement action against you. Tightening that loophole around research use only compounds would be the first step."
But is it? Specific legislation would make it easier, but is it necessary? In the US, the FDA/DoJ has successfully brought a number of prosecutions of online RUO vendors (although good lawyering can greatly minimize the possibility of prison time).
An academic warns unregulated compounds remain easy to buy online despite existing rules.
