Can L-Arginine help gains? How long for it to take effect?

This is going to sound weird, but I hope that the L-Arginine I started taking yesterday has NOT taken effect yet, because that would mean the thickness I saw tonight after my session is because I am making progress, and not because I am suddenly taking a supplement. Tonight was the first night that I could not easily close my thumb and index finger around my shaft and make them touch. I was really excited.

Having said all of that, how long for L-Arginine to take effect, and can it assist with gains due to better erections?

When I first took L-Arginine I noticed a reaction within the first few hours. It wasn’t as pronounced later.

Night (and other) wood is an important part of penile health.

[TL;DR: “wood is good”]

The “chemical PE” guys have shown that forcing erections for long periods will give gains. But those erections are harder and last much longer than you’re likely to get from L-Arginine.

Arginine may take effect in 2~3 weeks on your cells, but for you to see visible effects on veins that would take for a athlete 6 months, for a normal person maybe 9 to 12 months.

If you are talking about better EQ that could be a concentration of 3~5g, maybe in a week. But be advised that your body will adapt to the substance, so when you stop using it, performance will decrease until it desensitizes to it, and that will take sooome time.

What is your opinion on topical L-Arginine?

I add some to my lube. I *think* there’s some small benefit for EQ, but it’s so small it’s hard to quantify. I continue to add it to new batches of lube because it’s cheap and *might* be doing something useful.

If you have some on hand, you might experiment. From my experience, it wouldn’t be worth your while to buy some just to try it.

Three times now, once last week, and twice this week, I have been unable to complete my PE session without orgasm. This is extremely annoying and discouraging. L-Arginine is supposed to sort of supercharge your sex drive right? Could these failures be because it is finally taking effect and I am going too long between orgasms and it just can’t take the stimulation? I’m going to try ejaculating more often to see what happens. This sucks.
