It is very true that certain antidepressants can vastly increase LSA/D experience - but NOT Tricyclics. The previous generation of antidepressants were MAOIs (Mono Amine Oxidase Inhibitors), which essentially work by stopping the breakdown of seratonin-derivitive hormones and triptamines, thus extending and intensifying any drug experience, especially hallucinogenics.
SWIM has tried good quality seeds of the same batch both with and without Syrian Rue - a potent natural MAOI - and the the combo kick it into a whole new level!
Cautions:
The trigger dose of Syrian seems to be 3g, and larger doses WILL NOT yield better results, only worse stomachs.
As with all MAOIs be aware of what foods not to eat - mainly cheeses and red wine - but it might be an idea to find a full list.
