from Tikhal;
WITH TMPEA
(with 150 mg harmaline, 200 mg TMPEA (2,4,5-trimethoxyphenethylamine) [20 min]) "A very faint peripheral visual flicker was noted at 40 minutes. By 80 minutes, a decrease in coordination was apparent and walking required somewhat more attention than normal. This incoordination increased gradually, peaking at three hours. By this time the visual latency characteristic of harmaline was pronounced (when rotating the head or gazing quickly in a different direction, the prior images exit the visual field in a multiple wave fashion in a direction opposite to the motion). At no time were there any detectable effects on thought, and there was no open or closed-eye imagery, with or without music. No effects were detectable at the five hour point and sleep was easily achieved shortly thereafter. In summary, there was nothing there that could not be explained by the harmaline alone.
WITH MESCALINE
(with 100 mg harmaline, 60 mg mescaline (3,4,5-trimethoxyphenethylamine) [20 min]) "At two hours I was in a pleasant state of physical relaxation, a fine sense of well being, and I found music most enjoyable. From then to the fourth hour, thoughts flowed freely, and it became obvious that insight was a major part of this experience. Normally unconscious thoughts were easily available. It was as if I could observe my mind in operation, as facts were weighed to form conclusions. By the sixth hour music was a thing of beauty, with the higher notes crisp and clear. The harmaline has probably worn off. Sleep at eight hours, and the next day was without any adverse effects. This was a remarkable experience, the insight of TMA, and the relaxation of MDMA."
(with 150 mg harmaline, 100 mg mescaline [15 min]) "A stomach ache developed at about 45 minutes, followed by a mild nausea which occurred intermittently throughout the next six hours. I felt comfortable, although there was a slight discoordination at about two hours. Walking was never a problem but did require more concentration than normal. Colors on the television were obviously more intense, and highly saturated at this point and moderate photophobia developed. Even a fire in the fireplace was distracting, and stereo was best enjoyed in the dark. Attempts at sleep did not work until the ninth hour. Upon awakening there was a feeling of dehydration but otherwise no ill effects. Mild looseness of stools was present later that morning. Since experiments using only mescaline at doses between 80 and 120 mg resulted in no CNS effects at all, it seems clear that the MAO blocking effects of the harmaline were crucial to this experience.

As Morninggloryseed has already mentioned most of the warnings over harmaline type MAOIs are well meaning but based on total misunderstanding; harmaline has a very high safety profile as is contested by who knows how many 100s years use in the Amazon. Mescaline too.
I have used beta-carbolines+2C-C many moons back;
"8 dec possibly 1st ever human trial of chlorohuasca; (P.harmala+20mg 2c-c) potentiation approx x2? Lightly sensory perhaps more stimulant – no problems."
I really wouldn't want to give the impresssion for a nano second that mixing harmaline with novel synthetics is safe; of that nothing can be said but mescaline looks fine
