During the last 5 weeks, I’ve been conducting a test.
Once a day, I took an over‑the‑counter amino acid supplement said to boost blood flow: 1,000 mg of L‑arginine and 750 mg of L‑citrulline. These so‑called “blood‑flow vitamins” are supposed to increase circulation everywhere — including the naughty bits. But do they actually deliver?
I took L-arginine for the first 2.5 weeks, and L‑citrulline for the following 2.5 weeks. So, which one is better?
L‑Arginine
L-Arginine is a naturally occurring amino acid that the body uses.
When taken as a supplement, it acts as a vasodilator — meaning it helps open up blood vessels. In theory, it should work a little like Viagra (keyword:
little) in small doses. But it definitely falls short of that… although not completely.
I took my first pill on June 25th in the morning. Day 1? Nothing. Day 2? Nothing. And so on.
But on Day 5, I decided it was time to test it in a real situation. Found a random girl, booked a session, and was at her place two hours later — with nothing else in my system (no Viagra, Cialis, or other ED drugs). It was risky, but worth it for the experiment.
Long story short? It fell short. I didn’t feel any difference — neither in how easily I got hard nor in recovery time between rounds.
Still, I had started the experiment and didn’t want to quit just because Day 5 didn’t impress. I thought,
“Maybe the body just needs time to adjust,” so I kept taking it daily.
On Day 11, I had another pre-planned session. Again, no other ED drugs in my system.
This time, it felt like the pills had started settling in — or maybe my body had adapted. There
was some improvement. Slight, but noticeable: I felt it was a bit easier to get hard for round two.
That said, it didn’t improve much beyond that.
Takeaway on L‑Arginine
Worth it? Meh… not really. It’s
far from being a proper substitute for Cialis or even Sildenafil (Viagra).
Maybe it works better if taken continuously for a full month or more, but for now, I’ll stick with my usual Cialis or Sildenafil.
If you're hoping for something close to those effects — this ain't it.
L‑Citrulline
L‑Citrulline works a bit differently. It’s a non-essential amino acid that your body converts into nitric oxide, which helps arteries relax and promotes better blood flow throughout the body.
I took my first pill on July 13th. This time, I waited 8 days before visiting a girl.
When I finally tested it, the effects felt
similar to what I experienced during my second L‑arginine session.
However — and this surprised me — I actually felt the effects
less with L‑citrulline than I did with L‑arginine.
Takeaway on L‑Citrulline
Worth it? Not for me. If I
had to choose between the two, I’d go with L‑arginine — even though that’s not saying much.
Bottom Line
I will go back to the good old known ED medications that works.
That said, I´m open to try other supplements.
