^^^The 0.7mg redose at 3hrs increased the peak duration and duration in general. As for the intensity, its hard to say because at the same time I also got a cannabis joint going, so I did feel an increase of overall effects. 8)^^^I've used both garlic extracts and L-Arginine before, mostly with AL-LAD and with stimulants, also to combat the vasoconstriction. You gotta take them about 2 hours before tripping and more may be consumed during and/or after the trip. With L-Arginine you want to be careful as it spikes up your hormones and may make you aggressive (thus spoiling a trip), especially if you have a tendency to be so. Besides aforementioned, you can also use Magnesium (careful if you have a natural low blood pressure as it will lower it even more), Agmatine, dark chocolate (natural beans are preferred), cayenne pepper, cannabis and alcohol to dilate your blood vessels. I will try it out with DOC soon to see what works best with it and post my results!
I recommend large doses of 2C-P if you are looking for a very visual experience, nothing ever got me seeing such complex and long-sustained OEV's like 2C-P. Also combinations of 4-sub tryptamines (especially 4-Aco-MET) and mescaline or it's analogs are pretty colorful and visual for me. The most extreme OEV hallucinations are seen with smoked DMT and DPT for me - nothing comes even close, but they are quite short lived and might be very frightening and confusing.And yes, DOC is awesome! %)
