Like its predecessor Viagra, Tadalafil is also used to treat male erectile dysfunction.
A more embarrassing alternative to treatment after the cycle is a drop in libido due to a sudden lack of excessively stretched testosterone levels in the body, which usually leads to ED.
Tadalafil is the raw material of Cialas.
Tadalafil is a male sex promoter drug. Tadalafil is more durable than Viagra. The effect can be felt anywhere within 36-48 hours.
Tadalafil's role is to help blood vessels relax and increase penile blood flow during sexual arousal, thereby improving erectile function.
