Start with half of a capsule or less
I am so glad I read some reviews before buying this product yesterday. I opened the capsule and poured half into a water bottle. I figured I could take the other half if I did not feel anything. The effect was very strong from half of a capsule. I felt flush and warm and a bit sick to my stomach in about an hour. I took it mid-afternoon in case it made it hard to sleep. After eating dinner, I felt better. It worked as intended later that night. I would recommend this product, but try half a capsule first.

Great for energy workouts. Caution: Half the dosage!!
This does get you pumped and anxious. However, the side effects are real, ranging from: nausea, chills, high heart rate, cold sweats, goose bumps, and even sleep deprivation. When taking this split the dosage in half taking it with gatorade/water/food. Taking the whole pill on an empty stomach will make you ill to the stomach and feeling like you have the flu. I'm 6ft 220 and i felt like a lamb after taking it on an empty stomach prior to a workout. You will get amped, pumped, but be careful of the side effects on taking the full dose and cut it in half.

I think I know what might be the problem
Why would they sell this product in a capsule form? They should sell it as a tablet so that it slowly disolves in your system instead getting hit with it all at once with a capsule. I would recommend pouring the capsule into a drink, like Gatorade, and drink slowly!

Use caution with this product!
I took one capsule at 12:30 in the afternoon and I did not sleep that night, at all. I started to feel the effects within an hour after taking it. Within two hours my heart was racing and I felt warm and started perspiring then I got chills. It was not a good experience and I do not recommend this product.

does the job but feeling jittery
After checking out all your guys' reviews, so i decided to give it a try. I tried to leave my stomach empty at 3 pm, and i felt so horny after an hour. I went to the gym and did an intense workout but my heart rate jumped really fast and sweating badly. It did increase your sexual desire and penis gets solid rock hard, but I don't think it's good for a workout.

bad reaction
Bought the Yohimbe 451 when transformation program I was on recommended it. After taking it, during cardio I had trouble my resting heart rate below my 90% max. After cardio I was shaky, and wasn't even sure I'd be okay on the walk home. I made it, but I had to take breaks along the way. It's been 4 hours and I'm still shaky and experience heart rate increases from minor to moderate activity. Never taking it again and I do not recommend it.

Works good if you can withstand the side effects.
Product worked exactly as described, but about an hour and a half after taking the tablet I experienced some unwanted side effects. I Googled the side effects of this product I seem to have almost every one mentioned. I experienced nausea, upset stomach, chills, sweating, insomnia, and frequent trips to the restroom all night. The effects lasted for about 8 to 9 hours and left me feeling like I had a hangover the next day. Thinking it might have been a fluke, I tried the product one more time only to experience the same results. I give the product 3 stars, because it did work, it just didn't work like I had hoped.

BEWARE-Bad Outweighs good
Be careful when you take this. I took this supplement because it called for it in a 12 week workout program I just started. Took one dose and went to the gym and everything was fine until later that night. Could not go to sleep. had goose bumps all over my body. Sweaty hands and body sweat. Had the feeling of anxiety that night and the next day. I went to the doctor and he said that this dosage is very high and it caused me to have a anxiety attack. He prescribed me 2 Xanax to get me through it. I just took the first one and feel better already. I would NEVER take this again. Please don't take unless your doctor recommends this. This should not be over the counter and please take my word for it. Would not wish this feeling upon my worst enemy.

Made a big difference with my ED symptoms
I purchased this product based upon my positive findings in the research of Yohimbe and Yohimbine HCL.

Similar to other reviews written here, I too found the single dose to have a strong effect on heart rate and making me feel "jittery". Different to other reviews here, I did not experience upset stomach or other side effects.

Despite the side effects mentioned above, I would highly recommend this supplement for sexual health and positive effects on mild ED symptoms. It has worked great for me each time I have taken it, now having taken it 6 times over the last 3 weeks. I experienced a strong erection each time, within 1-3 hours of taking the supplement. The ability to get and maintain an erection lasted for approximately 8-12 hours post consumption.

What has worked for me is: 1) take before noon so you will not have its effects disturbing your sleep, 2) take with food, 3) drink cold water after taking it, 4) do not perform strenuous aerobic exercise after taking this supplement as it produced a racing heart rate and body sweat for me. Normal physical activity is fine, just would not recommend working out or being in hot conditions after taking the supplement. Lastly, because I am using it to obtain a stronger erection, I do not take daily and only take on days where sexual activity with my spouse is likely.

I wanted to be thorough here, in hopes that anyone considering this will understand the pro's and con's from someone who's taken the supplement for more than 3 weeks.
