Saw Palmetto works like propecia but side effects are more severe than propecia. It blocks both 5-alpha reductase type I & II. so Testosterone does not convert to DHT, no DHT means no sexual function. Some people using SP also suffer from low total T and free T or in other words they are hypogonadal. The only solution is go on TRT for the life.
SP is very potent and dangerous herb.It should not be sold without clear warnings.
I am also one of it's ex-user and have been handicaped for the last 12-13 months.
if you live in Canada or USA complain to health Department.
To think SP is safe is like some body thinking a bite from Cobra might be safe.
How are you? The most common complaints when using saw palmetto include stomach pain, nausea, vomiting, bad breath, constipation, and diarrhea. Stomach upset caused by saw palmetto may be reduced by taking it with food. Some men using saw palmetto report difficulty with erections, testicular discomfort, breast tenderness or enlargement, and changes in sexual desire. Saw palmetto may have effects on the body's response to the sex hormones estrogen and testosterone, but no specific effect has been well demonstrated in humans. It would be best to discuss this with your doctor for proper evaluation and for alternative supplements. (http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-sawpalmetto.html)
