i dont get it, icariin is shown to "mimic" testosterone......so by saying "mimic" they mean imitate....what is it imitating, the anabolic effects of testosterone or the sexual benefits?? is it boosting testosterone?? i just dont get it, i tried searching it and i couldnt find much....i didnt search the forums so i will do that now...if anyone can help me that would be great thanks guys

I have seen quite a few studies on the topic- short version- icariin has some cortisol and estrogen-antagonistic qualities, mood elevation, increases in bone mass and density, and also has some very noticeable effects on ACh- plus, at higher doses, it is a strong PDE-5 inhibitor. The conglomeration of several different aforementioned effects exerted by icariin parallel those of testosterone, but icariin does not directly effect the AR- rather, it antagonizes E receptors and also competes with cortisol for binding sitesDirk Tanis, BA, MSci

AIM: To evaluate the testosterone mimetic properties of icariin. METHODS: Forty-eight healthy male Sprague-Dawley rats at the age of 15 months were randomly divided into four groups with 12 rats each: the control group (C), the model group (M), the icariin group (ICA) and the testosterone group (T). The reproductive system was damaged by cyclophosphamide (intraperitoneal injection, 20 mg/kg x day) for 5 consecutive days for groups M, ICA and T, at the sixth day, ICA (gastric gavage, 200 mg/kg x day) for the ICA group and sterandryl (subcutaneous injection, 5 mg/rat . day) for the T group for 7 consecutive days, respectively. The levels of serum testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), serum bone Gla-protein (BGP) and tartrate-resistant acid phosphatase activity in serum (StrACP) were determined. The histological changes of the testis and the penis were observed by microscope with hematoxylin-eosin (HE) staining and terminal deoxynucleotidyl transferase biotin-dUTP-X nick end labeling (TUNEL), respectively. RESULTS: (1) Icariin improved the condition of reproductive organs and increased the circulating levels of testosterone. (2) Icariin treatment also improved the steady-state serum BGP and might have promoted bone formation. At the same time, it decreased the serum levels of StrACP and might have reduced the bone resorption. (3) Icarrin suppressed the extent of apoptosis of penile cavernosal smooth muscle cells. CONCLUSION: Icariin has testosterone mimetic properties and has therapeutic potential in the management of hypoandrogenism.
you get a nice dose of it in STOKED!

thanks and would you choose STOKED! over RPM for the icariin or what?
would staking the two be beneficial ??

12-10-2008, 08:41 PM
oh im a stim junkie lol...if you did what would you think between the two...just by looking at the profile of ingredients?

what do you think of this protocol?
2 stoked and 1 RPM in the AM
3 RPM around 3:00PM (when i lift)
2 stoked with dinner......
hows that look?

I would take a look at these popular products. Also, I wouldn't stack them. Try them one at a time to see what works best for you.
1.) Applied Nutraceuticals: RPM
2.) Applied Nutraceuticals: Drive
3.) Core Nutritionals: Core Zap
4.) Competitive Edge Labs: PCT Assist
5.) BCS Labs: 1.) Icariin 2.) phenom 3.) phenom amped
6.) bulk icariin : powder here on nutra or Live Long Nutrition: Icariin 50 over at bb
7.) Anabolic Innovations: Stoked
if you like stims then RPM, Core Zap, and phenom amped might be your favorite. Personally I think the most value in Icariin is pre-workout. So I only use it once a day. Others would argue that point but I'm talking about MOST value. Also, you'll save a bit of money. Also, you should cycle it. Most people say 4-8 weeks on and 2-4 weeks off.

I would use icariin if you are having issues with ED/libido from stronger test boosters or for pre-existing ED.This is a pro-sexual compound and should not be considered as something along the lines of 6-OXO,Activate Extreme etc.It is within a seperate class altogether.
A test booster or PH along with icariin would make for a sweet stack as far as improving body composition and sexual well being,IMHO.I will get into this further when I finish the write up for Live Long Nutrition's Icariin-500.
Here's a post supporting icariin's novel role in treating ED,taken from the linked thread.I highly recommend this thread to anyone interested in icariin,great discussion was had.
New Icariin Study - Mind and Muscle Forums
[quote name='Benson' date='Mar 9 2006, 06:46 PM' post='314433']
Came across this recent study on icariin, an erectogenic flavonoid of Epimedium sagittatum (Horny Goat Weed). It appears to enhance erectile response not through PDE-5 inhibition like sildenafil and related compounds but through a novel mechanism of action, the most interesting being a change in percentage of smooth muscle. This would mean that it would not be accutely very active but over time would likely improve erectile response in a more permenant manner.

Effects of icariin on erectile function and expression of nitric oxide synthase isoforms in castrated rats.
Liu WJ, Xin ZC, Xin H, Yuan YM, Tian L, Guo YL.
AIM: To investigate the effect of icariin on erectile function and the expression of nitric oxide synthase (NOS) isoforms in castrated rats. METHODS: Thirty-two adult male Wistar rats were randomly divided into one sham-operated group (A) and three castrated groups (B, C and D). One week after surgery, rats were treated with normal saline (groups A and B) or oral icariin (1 mg/[kg.day] for group C and 5 mg/[kg.day] for group D) for 4 weeks. One week after treatment, the erectile function of the rats was assessed by measuring intracavernosal pressure (ICP) during electrostimulation of the cavernosal nerve. The serum testosterone (ST) levels, the percent of smooth muscle (PSM) in trabecular tissue, and the expression of mRNA and proteins of neuronal nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase (eNOS) and phosphodiesterase V (PDE5) in corpus cavernosum (CC) were also evaluated. RESULTS: ICP, PSM, ST and the expression of nNOS, iNOS, eNOS and PDE5 were significantly decreased in group B compared with those in group A (P 0.01). However, ICP, PSM and the expression of nNOS and iNOS were increased in groups C and D compared with those in group B (P 0.05). Changes in ST and the expression of eNOS and PDE5 were not significant (P 0.05) in groups C and D compared with those in group B. CONCLUSION: Oral treatment with icariin ( 98.6 % purity) for 4 weeks potentially improves erectile function. This effect is correlated with an increase in PSM and the expression of certain NOS in the CC of castrated rats. These results suggest that icariin may have a therapeutic effect on erectile dysfunction.

dont know why but RPM makes me annngggrrrryyy and mean, not a nice person. good preWO supp definitely.
ive tried bulk icariin throughout the day, made me a bit horny but thats about it, i prefer it with stim pre workout.
how anti-estrogenic is it? anybody know?

Aβ1−40 • aluminium • icariin • learning and memory • malondialdehyde • superoxide dismutase
Abstract INTRODUCTION METHODS RESULTS DISCUSSION ACKNOWLEDGEMENTS REFERENCES
The present study examined the protective effects of icariin against the learning and memory deficits in aluminium-treated rats and its potential mechanisms of action.
Qualified rats were treated with 1600 p.p.m. AlCl3 in drinking water for 8 months and the ability of spatial learning and memory was tested by the Morris water maze. In the place navigation test, aluminium administration significantly increased the mean escape latency and searching distance. In space probing test, aluminium markedly decreased the searching time and searching distance in the quadrant where the platform was originally located. All tests indicated deficits in rat spatial learning and memory induced by aluminium. Icariin treatment (60 and 120 mg/kg, by gavage for 3 months) dose-dependently protected against the development of aluminium-induced spatial learning and memory deficits.
To examine the mechanisms responsible for the protection afforded by icariin, the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the hippocampus were assayed biochemically and the level of Aβ1−40 in the hippocampus was determined immunohistochemically. Icariin treatment significantly increased SOD activity and decreased MDA and Aβ1−40 content in the hippocampus of aluminium-intoxicated rats.
In conclusion, the present study demonstrates that icariin is effective in improving the spatial learning and memory of aluminium-intoxicated rats. The mechanisms responsible appear to be due, at least in part, to an increased anti-oxidant capacity and decreased lipid peroxidation and Aβ1−40 levels in the rat hippocampus."
