Tadalafil, Vardenafil

1) Tadalafil, Vardenafil, Sildenafil citrate, Sildenafil Mesylate are used to treat erectile dysfunction (impotence; Inability to get or keep an erection) in men. They are in a class of medications called phosphodiesterase (PDE) inhibitors. They works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. We can provide raw material of this products, purity is around 99. 9%.

2) Yohimbine is an ýÁ[2]-adrenergic antagonist produced from the bark of the yohim tree. It presumably acts on the paraventricular and preoptic brain centers associated with libido and penile erection. It has been reported that it is superior to placebo in a recent meta-analysis of seven randomized, placebo-controlled studies of yohimbine monotherapy. However, in a controlled randomized study of patients with organic erectile dysfunction taking 18 mg of yohimbine per day, no significant difference from placebo was found. Serious adverse reactions are infrequent, and its beneficial effects are modest at best. We can provide Yohimbine HCL powder, purity is 98%min.
