In short, such an enhancer does not exist.
There are certain practices that are more enjoyable on
MDMA, but nothing you would class as something that pottentiates the high or lowers tolerance, there is simply things that feel good on MDMA. Menthol inhalers are one such thing that are enhanced by being under the influence.
There is also many rumours about Vitamin C/Absorbic acid potentiating the MDMA. This is where the drinking of orange juice to get a stronger roll myth came about. Vitamin C WILL NOT potentiate MDMA, but there has been evidence to suggest that it prevents some neurotoxic damage. Eating Vitamin C or orange juice will not have any noticable effect on your high.
5-HTP is a bit more complicated, and
SWIM isn't entirely aware of the details of pre-loading 5-HTP but if he recalls correctly there is a risk of
Serotonin Syndrome f 5-HTP is used before MDMA in order to potentiate the high. SWIM is not entirely sure on this issue so clarification would be greatly appreciated.
