Pure Sildenafil Powder

Genbay Biotechnology Co., Ltd. provides Pure Sildenafil Powder as a high-purity, pharmaceutical-grade chemical raw material supplied in a white to off-white crystalline powder form. Sildenafil is most widely known for its direct functional use in erectile dysfunction (ED): it helps men achieve and maintain an erection by improving blood flow during sexual stimulation. Its primary mechanism is PDE5 inhibition, which supports the nitric oxide–cGMP pathway involved in vascular smooth muscle relaxation. Sildenafil is also used in pulmonary arterial hypertension (PAH), where it helps reduce pulmonary vascular resistance and supports improved exercise capacity.
