RT3 Side Effects: What the Trials Reported

Almost everything known about rt3's side-effect profile comes from two phase 2 trials. The picture is consistent: the adverse events are overwhelmingly gastrointestinal, they track with dose, and they cluster during escalation. The larger issue is what has not been established yet.

Are Peptides Legal in the UK? The Actual Legal Position

The honest answer is that it depends entirely on what the peptide is sold for, not what the peptide is. Buying and possessing research peptides for laboratory work is lawful in the UK. Supplying them for human consumption is a criminal offence, and that distinction is the whole of the law here.
