Garcinia Cola Seeds as a Testosterone Booster: 100%+ Increased Testosterone and Powerful Aphrodisiac Effects

Written by | published on

Better than asparagus ;-) I have to admit, it has been a while since I've written about "natural testosterone boosters". In the last article that was remotely related to this topic, I even wrote that they are useless for 90% of the male population, because even if  they boost your testosterone levels by 10-20% this is very unlikely  to have the muscle building and fat burning effects that are marketed on the packages of and in the ads for respective products. Why? Well, even with real gear it takes more than just a 10% boost within the normal range before you see results ( learn more  | specifically Figure 2 where green is the large "normal" range). So why do I even bother about yet another rodent study dealing with the ability of a more or less exotic flowering plant found in Benin, Cameroon, Democratic Republic of the Congo, Ivory Coast, Gabon, Ghana, Liberia, Nigeria, Senegal and Sierra Leone and its ability to boost testosterone levels? If you want ...

Men Are Not Always Thinking About Sex. Study Says: There Are At Least 4 "Good" Reasons They Don't - Stress Is #1! Plus: A Proven De-Stress Protocol to Restore Your Libido

Written by | published on

If either of these individuals remind you of yourself, you should reduce his stress levels. Recent research suggest: The good old saying that "Men always think about sex!" is essentially untrue (The "!" indicates that I used the feminist version of this common "wisdom"). If we put faith in the results of a recent European study from the Department of Clinical Psychology at the Instituto Universitário in Lisbon, Portugal, the Department of Psychology at the University of Tromsø in Tromsø, Norway, and the Sexology Unit at the Faculty of Humanities and Social Sciences, University of Zagreb, Croatia, stress is the common denominator that distracts men from their original duty to do what has to be done for the survival of the human race ;-) Homo coitum quaerens aut evitarens? It may sound surprising, but unlike sexual function, the sexual desire of the male members of the human race has not been examined as extensively as the one of their female...

Gingko Biloba, Your Dopaminergic Brain Viagra. Plant Extract Stimulates Sexual Arousal via the Paraventricular Nucleus and the Mesolimbic System.

Image 1: Gingko biloba trees are one of a kind, with no close living relatives (image Schwabe Pharm .) I bet you got one of those Viagra spam mails, today, as well, didn't you? Well, although I assume you would not need the small blue pills, anyway, you may be interest to read that researchers from the People's Republic of China may have found a viable Viagra alternative in a longstanding (pun intended ;-) ingredient of Traditional Chinese (and meanwhile also Western) Medicine : Gingko biloba . In order to elucidate the underlying mechanisms of previously ( Yeh. 2010 ) observed beneficial effects of Ginkgo biloba extract on noncontact erections in male rats, Yeh et al. ( Yeh. 2011 ) recorded both copulation, as well as non-contact erections in a group of 20 male Long-Evans (telling name, isn't it?) rats, which had been randomly assigned to a treatment ( 50mg/kg body weight Gingko biloba extract [EGb 761 from Schwabe Pharmac...

News on USP Labs' "Pink Magic": High Dose Massularia Acuminata Increases Testosterone and Makes Bucks Horny as Hell

Written by | published on

Faithful readers of the SuppVersity will probably remember my short write-up on USP Labs Test Booster " Pink Magic ". Now that the initial fuss about how "brilliant" and "unique" the product is, is over there is finally another study on the efficiency of its main ingredient, a shrub called massularia acuminata . Two scientists from Nigeria ( Yakubo. 2011 ) published an article on the "Effect of Aqueous Extract of Massularia acuminata Stem on Sexual Behaviour of Male Wistar Rats" in the January issue of Evidence Based Complementary Alternative Medicine . The scientists found that supplementation with 500 and 1000 mg/kg body weight (equivalent to 6.8g and 13.6g) of an aqueous extract of the stem of the botanical... ... increased the frequencies of mount and intromission. In addition, the ejaculation latency was significantly prolonged ( P < .05). The latencies of mount and intromission were reduced significantly whereas ejaculation fre...

DHT Safer Than Previously Thought: High Blood DHT does not Induce Prostate Cancer

Written by | published on
Regular visitors of the SuppVersity will know that the stigmatization of DHT goes without reasonable and conclusive scientific research. In their editorial to the Annals of Internal Medicine Swerloff & Wang ( Swerloff. 2010 ) conclude from the results of more recent studies into the various effects of DHT on different tissues: In normal men, serum DHT levels are approximately 10% of the serum testosterone levels, whereas intraprostatic DHT levels are much higher than serum levels, with the intraprostatic DHT–testosterone ratio being 7 to 8 (12). Although the authors did not measure DHT levels in the prostate after DHT administration , Page and coworkers (13) recently reported that prostatic DHT levels did not increase when pharmacologic doses of DHT were administered (Page S. Personal communication.). These findings are consistent with those of Marks and colleagues (12), which demonstrated that administration of testosterone to mildly testosterone-deficient men increased serum t...

Arginine + Yohimbine Effective for the Treatment of Erectile Disfunction

Written by | published on

Although, this is a topic men do not tend to speak about, statistics say that it bothers more people than one would think: Erectile disfunction. Certainly, Viagra & Co are the most popular tweaks for "getting it up" again, a new study from Iran ( Akhondzadeh. 2010 ), however, suggests that a combination of arginine + yohimbine may prove effective, as well. In a 4-week, double blind study of parallel groups of patients with mild to moderate ED, the scientists report a significant difference in ED within the group supplemented with a one capsule of SX (a commercial preparation consisting of l-arginine + yohimbine): The difference between the two groups was significant at week 4 (endpoint) (P=0.03). Four adverse events were observed over the study. The difference between the SX and placebo was not significant in the frequency of adverse events. Unfortunately, the funding of the study suggests that there may have been a certain bias towards "proving" the advertisem...

Anti-Androgenic Effect of ATD

Written by | published on
Image
A few month ago a study by Svensson ( Svensson. 2010 ) caused quite a fuss in the supplement world. The scientist had injected huge amounts of ATD into his laboratory rats and found that "the aromatase inhibitor 1,4,6-androstatriene-3,17-dione (ATD; 60 mg/kg/day s.c.) decreased behavioral disinhibition in testosterone-treated rats (without affecting accessory sex organ weights)". In view of the huge dosage, I simply ignored the results of that study until I recently stumbled across a whole bunch of papers which support the notion that ATD is in fact anti-androgenic, in that it does reduce testosterone receptor binding in the brain ( Kaplan. 1989 ). The negative effect of ATD administration on mating behavior and success (2x ejaculation) in testosterone treaded rats is alarming (cf. figure 1): Figure 1: Effect of ATD supplementation on sexual performance of hypogonadal rats treated with testosterone + propylene glycol (T+PG), testosterone + ATD (T+ATD) or ATD alone. ...

Androsterone a Major Factor in Sexual Desire

Written by | published on

A 2006 study ( Bloch. 2006 ) (re-)published in Arch Gen Psychiatry. 2006;63:450-456 had a closer look on the effect of neurosteroids on sexual function in men. The results clearly indicate that androsterone (ADT, chemical structure on the left; source: HMDB: Androsterone ), a potent neurosteroid,  some "bros" mis understand as a precursor or pro-hormone to testosterone and estrogen (actually it is a testosterone metabolite), has a regulative effect on sexual function in men. The scientists measured cerebrospinal fluid (CSF) levels of several steroids and monoamine metabolites and found low androsterone levels to be the major correlate of decreased sexual desire : "...the change in CSF androsterone levels was correlated with the change in the severity of decreased sexual interest between testosterone-replaced and hypogonadal conditions (r=−0.68; P<.05)." In this context the following table, summarizing the correlation of ADT, DHT and T and selected sympt...
