I'm sure most of you know that yohimbe can be dangerous: if you use the wrong dose, it can give you rapid heart-beat, high (or very low) blood pressure, anxiety and what-not. We all read the horror stories here and elsewhere.
Well, I definitely experienced some of that...twice. The first time I took about 150mg of yohimbe, just to try it (standardized to 8% yohimbine, from BAC, no longer available, i believe) and what happened was not good. I started feeling a tingly sensation as I was in the grocery store, and soon enough I was in a full-blown anxiety attack, which I had to keep at bay taking long deep breaths until I could get back to my car. At that point (after 1h of taking it) I couldn't tell if I had shat in my pants or not. Turns out I was only heavily sweating from my ass crack. The state lasted a few hours. I went for a run, then I took a warm bath. Controlled my BP and it was like 155-85, which freaked me out until I realized it was getting better...slowly. I ended up taking some Xanax to accelerate the come-down a bit. Needless to say, this was NO FUN. WTF was I thinking taking crazy doses of that (and other) herbs?
Other symptoms were some tightness in the base of the throat, cold feet, sensation of fever. All would pass after 2-3 hours.
I didn't give up, though. I insisted 4 days later, this time before having sex. What happened was OMFG, fun!!!. I unleashed the beast. I had the biggest erection and most energetic type of libido that I probably ever had (I'm in my mid-40s). After some hour or so of animal sex, I started feeling jittery and my thoughts racing. Turns out my dose was still too high (I had eyeballed it and was probably 50% too much) ... but I wasn't going to stop
I stabilized my dose at about 50mg yohimbe (about 3-4mg yohimbine, although who really knows) and the day after, I had the most amazing sex I probably had in my whole life, for 15 days in a row. I took it every other day or a bit more than that. The effect lasted for 2-3 days! The initial energy was only for a few hours, but the granite-hard erections went on for almost 4 days after I stopped taking it (and counting...)
The most interesting thing is that, after reading a few studies, I learned that yohimbe acts independently from testosterone, both on erections and libido (and even after rats were anesthetized in their genitals, they would chase females for mating)
I am healthy, and don't have ED, but was looking for a sexcreational drug, to enhance the experience. Boy did I find it. Hopefully taken in the right-doses and with some cycling, it won't bring about any other side-effects. Yohimbine is currently used chronically as a ED therapy, although most people prefer cialis for that. I don't. I like much more the "complete" state that Y brings about, as opposed to the "robotic arm" feeling of tadalafil/sildenafil. I got nothing against those compounds, but they feel a lot less natural in the experience they facilitate.
A few confounding factors: I'm taking selegiline 5mg/day for 4 years now and I had taken cabergoline and toremifene, but stopped 15 days before this experience. i don't *think* they would stay in my system, would they?
I'm also taking zinc, Mg, boron, selenium, and fenugreek, for over a year now. I also took some citrulline about 5 days before the experience.
