maca?

[demal]

i have just recently heard about this maca i would like to know the benefits from it and if it is worth buying, also does this increase testostrone?

thanks

It's reportedly an aphrodisiac, as well as benefiting other areas of sexual health. To my knowledge it has never been shown to raise androgen levels.

Is it worth buying? You have to decide that yourself. It's cheap and I have found it to be effective in the areas mentioned above.

Maca is made out of a combination of alkaloids that stimulate certain parts of the brain (such as the hypophysis and the hypothalamus) to produce different kinds of hormones (testosterone) that improve the sex drive and the libido.

somethin i just read

you took that from a site that is dedicated to selling maca... lmao.

[demal]

where else would it had been from

[Vipersg123]

where else would it had been from

maybe from a scientific journal testing whether or not maca effects hormone levels? Obviously someone selling the product is going to pimp it. hold on lemme see if I can find anything

This study was a 12-week double blind placebo-controlled, randomized, parallel trial in which active treatment with different doses of Maca Gelatinizada was compared with placebo. The study aimed to demonstrate if effect of Maca on subjective report of sexual desire was because of effect on mood or serum testosterone levels. Men aged 21-56 years received Maca in one of two doses: 1,500 mg or 3,000 mg or placebo. Self-perception on sexual desire, score for Hamilton test for depression, and Hamilton test for anxiety were measured at 4, 8 and 12 weeks of treatment. An improvement in sexual desire was observed with Maca since 8 weeks of treatment. Serum testosterone and oestradiol levels were not different in men treated with Maca and in those treated with placebo (P:NS). Logistic regression analysis showed that Maca has an independent effect on sexual desire at 8 and 12 weeks of treatment, and this effect is not because of changes in either Hamilton scores for depression or anxiety or serum testosterone and oestradiol levels. In conclusion, treatment with Maca improved sexual desire.



Effect of Lepidium meyenii (Maca), a root with aphrodisiac and fertility-enhancing properties, on serum reproductive hormone levels in adult healthy men.Gonzales GF, C?rdova A, Vega K, Chung A, Villena A, G??ez C.

Lepidium meyenii (Maca) is a Peruvian hypocotyl that grows exclusively between 4000 and 4500 m in the central Andes. Maca is traditionally employed in the Andean region for its supposed aphrodisiac and/or fertility-enhancing properties. This study was a 12-week double-blind, placebo-controlled, randomized, parallel trial in which active treatment with different doses of Maca Gelatinizada was compared with a placebo. The study aimed to test the hypothesis that Maca has no effect on serum reproductive hormone levels in apparently healthy men when administered in doses used for aphrodisiac and/or fertility-enhancing properties. Men aged between 21 and 56 Years received 1500 mg or 3000 mg Maca. Serum levels of luteinizing hormone, follicle-stimulating hormone, prolactin, 17-alpha hydroxyprogesterone, testosterone and 17-beta estradiol were measured before and at 2, 4, 8 and 12 weeks of treatment with placebo or Maca (1.5 g or 3.0 g per day). Data showed that compared with placebo Maca had no effect on any of the hormones studied nor did the hormones show any changes over time. Multiple regression analysis showed that serum testosterone levels were not affected by treatment with Maca at any of the times studied (P, not significant). In conclusion, treatment with Maca does not affect serum reproductive hormone levels.


Lepidium meyenii (Maca) does not exert direct androgenic activities

Maca is the edible root of the Peruvian plant Lepidum meyenii, traditionally employed for its purported aphrodisiac and fertility-enhancing properties. This study aimed at testing the hypothesis that Maca contains testosterone-like compounds, able to bind the human androgen receptor and promote transcription pathways regulated by steroid hormone signaling. Maca extracts (obtained with different solvents: methanol, ethanol, hexane and chloroform) are not able to regulate GRE (glucocorticoid response element) activation. Further experiments are needed to assess which compound, of the several Maca's components, is responsible of the observed in vivo effects.

thanks man!

Unfortunately everyone thinks that to mediate an anabolic response within the body you must take something that increase testosterone levels. Maca's effect on T levels are nothing special, but its effects on a certain growth factor are extremely substantial if the extraction is right along with the dose..

Has maca been shown to improve connective tissue and/or joint integrity? A friend told me that it may be a good alternative to other joint supplements, as I seem to be allergic to glucosamine.

Thanks!
