Tribulus terrestris, by Sopharma.

Tribestan is the most potent natural Testosterone-enhancing supplements in the world today. For the majority of people using it, strength levels will increase that will result in gains in muscularity and mass because you'll be able to train more intensely and heavier. Also protein utilization will increase and since muscle is comprised of and built with protein - the more you can utilize, the greater the possibility for growth. Tribestan is an ultra concentrated form of Tribulus Terrestris and it takes 2000 lbs of tribulus terrestris to make 40 lbs of Tribestan. It was originally designed for and continues to be used to treat several medical conditions involving impotence and sterility. It has a marked effect on testosterone levels and users report a profound increase in sexual libido as well as more frequent and prolonged erections. Females experience increased sex drive as well.

Research indicates that when you take Tribestan, your pituitary gland releases Luteinizing hormone, which is responsible for stimulating the testes to produce Testosterone. It's common for levels of both Luteinizing hormone and Testosterone to decrease when you are taking steroids or even when you overuse the testosterone boosters (like andro, norandro etc.) This is because when the body senses an external source of testosterone, it will decrease the amount of natural testosterone it produces to maintain homeostasis (feedback mechanism). The reason why Tribestan works so well is because it is not an external source of testosterone nor a precursor to testosterone, or does it supply testosterone. It stimulates your body to produce more of its own testosterone. Even in situations where people are taking steroids and their natural testosterone production has been diminished, it can help raise testosterone production back up to normal levels.

Also, it is perfectly alright for women. There has been clinical studies on menopausal women that show Tribestan can reverse the effects of menopause. Testosterone levels in women become slightly elevated, but not enough to result in any masculinizing effects. They are able to lose body fat more rapidly, increase strength and lean body mass with no water retention. Women will not experience any negative side effects from Tribestan use except maybe an increase in libido. However, they need to stop taking it 5 days before their period. After they start their period they can resume using Tribestan. When lutenizing hormone levels increase in women, follicle stimulating hormone (FSH) does as well to keep hormones in balance. (FSH levels do not increase in men).
