Why it works
It blocks PDE5, the enzyme that clears cGMP. cGMP is the signal that tells vessel walls to relax, so blocking PDE5 keeps nitric oxide's effect going instead of switching it off. PDE5 also sits in the prostate, the bladder and the lung arteries. That is why one drug treats erectile dysfunction, an enlarged prostate and pulmonary hypertension.
Where it fits
Tadalafil is a move in 5 protocols. Each one opens the plan it sits in.
What people say
Here is what doctors, influencers and men online say about Tadalafil, word for word.
Experts
Clinicians, authorities
“TADALAFIL (tah DA la fil) treats erectile dysfunction (ED). It works by increasing blood flow to the penis, which helps to maintain an erection.”
“These undeclared ingredients may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels.”
“Unlicensed erectile dysfunction medicines can be especially dangerous for people with heart disease, high blood pressure, or those taking other medications, and can raise the risk of heart attack, stroke and dangerously low blood pressure.”
Gurus
Podcasts, channels, influencers
“The mortality, heart, stroke and dementia reductions come from one observational study; they show association, not proof”
“those who were treated with tadalafil for urogenital issues (including ED) showed a 34% decrease in risk of all-cause mortality, a 27% decrease in risk of heart attack, and a 34% decrease in risk of stroke”
Regular people
Forums, reviews, comments
“although it found an association between long-term tadalafil use and glaucoma, it cannot prove that tadalafil caused the additional glaucoma cases”
“I have to take Tadalafil daily as my urologist prescribed it and have no issues going to the gym. I lift weights and exercise regularly.”
“FYI, before reaching for PDE5 inhibitors, please be aware that these seem to be ototoxic in some way. Common side effects are tinnitus and to a lesser extent hearing loss.”
