It Works!
Bad Memory; Before I took this suplement, I memory is very bad, I cannot memorize 2 or more digit numbers, just bad, When I took it, I notice my memory is getting better, I am able to memorize numbers again. As to down under, yes, it works too, I notice its different. Strenght - it also gave me enough strengt. What are we talking about here? lol!

What is this, a horse tranquilizer?!
Whoever designed this tablet clearly hates humans. It’s MASSIVE, dry as chalk, and feels like I’m trying to swallow a Lego brick wrapped in drywall. Every time I try, it gets lodged in my throat and I end up gagging like I’m in a bad TikTok challenge. Why on earth didn’t they make this a capsule?! It’s 2025, not the Middle Ages. I’m done .straight to the trash. I value my throat too much

BEST SO FAR
Best best best I have used different brands of L-Arginine like GNC,GAT,MB etc with 2 capsules once a time but this is something crazy now foods L-ARGINING is best i would say just 1 capsule made my whole workout easy with heavy lifting. Please buy it blindly

錠が大きいので慣れるまで飲みこみにくいですが、飲み続ければアルギニンとしての効果を実感できます。

Great for the gym
I’ve been using NOW L-Arginine 1,000 mg for a while and would definitely recommend it for anyone who works out regularly. I train three times a week for 45 minutes. With L-Arginine I have less fatigue during workouts, and post-workout muscle soreness is minimal. I take it about an hour before and the muscle pump kicks in almost immediately which seems to make the weight exercises move smoothly. One important note is that the tablets are huge, so be sure to swallow them lengthwise. Overall I think this is a good product at a decent price.
