How the ratings work
The longer explanation

This combination of stimulants will increase strain on the heart, may cause some physical discomfort, and has the chance to cause cardiovascular issues. The anxiogenic and focusing effects of stimulants can increase the chance of unpleasant thought loops and make the experience more uncomfortable, this combination raises these chances. Amphetamines will increase the neurotoxic effects of MDMA, in addition to causing further concerns of hyperthermia due to the inherent nature of the combination. It will also raise one's body temperature, also likely making the combination more neurotoxic.
