tried 5 Htp to help with mood while on PCT and had some terrible sides. Severe nightmares which ended in me waking up in panic and thinking i was being burgled several times a night, severe anxiety the following day lasting all day (similar to overdosing on cafffiene). I threw it in the bin straight after 2 days of use. I was using two tabs which is one tab below the reccomedded dose on the bottle. Beware.
On a side note i have started using St john wort to help with my OCD and anxiety and it is great. works well, no sides and elevated good mood, i would reccomend.
