Here’s an easy thing you can do that might work.

I read that 4 grams (4,000 mg) of arginine can help with ED. I have tried arginine in the past but never at this high a dose. But then I read this again, from a reliable medical source, so I tried it last night.

For experimental purposes, I try taking things at night and seeing if there is an effect when I wake up. If I wake up like a regular middle-aged man, then that means no effect. If I wake up like a 16-year-old, then that means it has had an effect.

This morning, after taking 4 grams of arginine last night, I woke up like a 16-year-old.

I can’t say for sure it was the arginine; it may just be a coincidence; it may have been the garlic I have been eating (2 cloves/day, crushed). It may be the exercise I have been doing, or the new sunlamp I use. It may just be springtime. Or all combined. Who knows? But it seemed I had a dramatic benefit from taking a large dose of arginine – the precursor of nitric oxide – right before bedtime.

So, I will try this again tonight, and see if I have the same effect.

In the past, I find sometimes thing work, and then they stop. Maybe I need a higher dose. 5 grams?

In any case, this is something you can try. It’s safe, does not require a prescription, and easy to do. There is even research to back up this approach.

If you try this, let me know what happens.

Here’s an article that studied 5 grams of arginine for ED:

BJU Int. 1999
Effect of oral
administration of high-dose nitric oxide donor L-arginine in men with organic
erectile dysfunction: results of a double-blind, randomized, placebo-controlled
Chen J1, Wollman Y,
Chernichovsky T, Iaina A, Sofer M, Matzkin H.
To determine, in a
prospective randomized, double-blind placebo-controlled study, the effect of 6
weeks of high-dose (5 g/day) orally administered nitric oxide (NO) donor
L-arginine on men with organic erectile dysfunction (ED).
The study included
50 men with confirmed organic ED who were randomized after a 2-week placebo
run-in period to receive L-arginine or placebo. A detailed medical and sexual
history, O’Leary’s questionnaire, a specially designed sexual function
questionnaire and a sexual activity diary were obtained for each patient. All
participants underwent a complete physical examination including an assessment
of bulbocavernosus reflex and penile haemodynamics. Plasma and urine nitrite
and nitrate (designated NOx), both stable metabolites of nitric oxide, were
determined at the end of the placebo run-in period, and after 3 and 6 weeks.
Nine of 29 (31%)
patients taking L-arginine and two of 17 controls reported a significant
subjective improvement in sexual function. All objective variables assessed
remained unchanged. All nine patients treated with L-arginine and who had
subjectively improved sexual performance had had an initially low urinary NOx,
and this level had doubled at the end of the study.


Oral administration
of L-arginine in high doses seems to cause significant subjective improvement
in sexual function in men with organic ED only if they have decreased NOx
excretion or production. The haemodynamics of the corpus cavernosum were not
affected by oral L-arginine at the dosage used.
