cubby2112 Posted March 26, 2010 Share Posted March 26, 2010 So, starting another supplement roundtable. I always learn a lot from these. After reading Martin Berkhan's post on supplements awhile ago, I've been rather interested. http://leangains.blogspot.com/2010/01/supplements-you-might-actually-find_09.html To cite what he cites and anyone who supports yohimbine cites: http://www.ncbi.nlm.nih.gov/pubmed/17214405 Res Sports Med. 2006 Oct-Dec;14(4):289-99.Yohimbine: the effects on body composition and exercise performance in soccer players. Ostojic SM. Institute of Sports Medicine, Sports Academy, Belgrade, Serbia and Montenegro. [email protected] The main aim of this study was to determine the effects of yohimbine supplementation on body composition and exercise performance in professional soccer players. The athletes (20 top-level male soccer players) were allocated to two randomly assigned trials. Subjects in the yohimbine group orally ingested tablets that contains yohimbine at a dose of 20 milligrams per day in two equal doses for 21 days. Subjects in the placebo group ingested an equal number of identical-looking pills that contained cellulose. There were no statistically significant changes in body mass and muscle mass within or between trials (p > 0.05) after the supplementation protocol. Percentage of body fat significantly decreased in the yohimbine group after the supplementation protocol (9.3 +/- 1.1 vs. 7.1 +/- 2.2%; p < 0.05). Furthermore, fat mass was significantly lower in the yohimbine versus placebo trial at postsupplementation assessment (7.1 +/- 2.2 vs. 9.2 +/- 1.9%; p < 0.05). There were no changes in exercise performance indicators (bench and leg press, vertical jump, dribble and power test results, shuttle run) within or between. trials (p > 0.05). No subject reported any side effects from yohimbine. The results of the current study indicate that supplementation with yohimbine combined with resistance training does not significantly alter the body mass, muscle mass, or performance indicators in professional soccer players. Nonetheless, yohimbine supplementation appears to be suitable as a fat loss strategy in elite athletes. That said, yohimbine is supposed to block alpha-2 adrenoreceptors, which downregulate the release of epinephrine and norepinephrine, two primary lipolytic hormones. This also gives beta receptor stimulators, like caffeine and synephrine/ephedrine a more powerful effect. Also, alpha-2 receptors are supposed to be dense in the trouble areas in men and women, such as the stomach, hips and thighs. The blocking of these receptors apparently helps to mobilize fat in those areas, so it will be preferentially burned. The great think about yohimbine, unlike caffeine, synephrine and ephedrine, is that there is no negative feedback loop associated with the blocking of alpha-2 receptors, or so I am told. Basically, your body won't release less epi and such from yohimbine. I don't know how much truth there is to that, because the body sure loves homeostasis. Correct me if there is any misinformation there, I just want to get the basics on it down, so everyone can be on the same page. Like Martin says, though, all this does sound rather hokey. I got some in powder form (yohimbine hcl) from trueprotein.com, which you must dose very carefully. I felt like a crack dealer, measuring out on a milligram sensitive scale. It has been about a week since I started, and I have this to say: it works. Maybe it is placebo effect, but I can definitely see it in the mirror, and I can only pinch half the fat I used to be able to. I am not going to say the pinch amount, because it is embarrassing. Intermittent fasting got me most of the way there, and yohimbine seems to work great for that last little push. Also, yohimbine hcl, 11-hydroxy-yohimbine and alpha yohimbine are recommended over yohimbe extract. Yohimbe is supposed to contain alkaloids (same family as caffeine, theobromine, etc.) other than yohimbine. These can have certain negative effects that you aren't as likely to get from pure yohimbine. You want yohimbINE, not yohimbE. Thoughts? I will get some pictures up in a week or two or three, and you guys can be the judge. Link to comment Share on other sites More sharing options...
