Super results seriously
Excellent potent product. Best I have ever used.I combine this with creatine mono (Allmax)and they truly compliment one another.For those not familiar with the process. This Arginine product produces nitric oxide that plays the part of widening your veins. Creatine causes your body to take on more water. With these guys working together that good water and nutrients that are consumed have an excellent flow through the veins. Well fed muscles grow quicker. Don’t worry about some water weight. That extra water weight acts as a reinforcer when pushing the weights. It’s lovely indeed. Water weight is easily lost so no biggie. If your anything like me you want to knock down workouts asap back2back. If so get some quality BCAA’s (Allmax again). Their products are also as pure and potent as this Jarrow sup. These products are gold. Not to be underestimated. I would go as far as to say no other products are in there league. Enjoy your PUMPS & GAINS!!

A Daily Must For My Body
Jarrow Formulas L-Arginine 1000mg, 100 Tablets- L-Arginine simply put is ONE of my daily supplements I don’t go without as my body reacts well to it. I take 1000mg a day before I workout and will always reorder as nothing works better in the gym for that pump I like the over all health benefits making this a solid buy. I rarely get sick, my body recovers faster from the gym and I do actually think this product aids in energy boost as well as bounce back time in the bedroom. Solid supplement and I recommend it for anybody that leads an active life style wanting alittle more out of life. Now I will say this particular product brand was my first time trying the product and I did finish the bottle but I re-ordered in an different brand that seemed to have even more of a kick. This brand worked for me but I like to switch it up and try different things, which seemed to give me even better results.

Excellent product
I have used L-Arginine for years, and I believe it is the most essential supplement in my stack (male, 53 yrs old). I take one of these 1000 mg tablets immediately upon awakening, and within 30 minutes or so I can feel more…”engaged”??…not sure what word makes best sense. I just know I feel more groggy when I forget to take it. I read one review that said, “I just feel like doing stuff”…that’s a good description! I take a second one in the mid- to late-afternoon.I’ve found the Jarrow to be a great product, and 1000 to be a good level for me and the best price-to-value. I’ve tried the 5000, but for the price, I didn’t sense a significant difference. I’m not sure if you can absorb that much at once, but I’m no nutritionalist. I’ve heard it doesn’t hurt to overdo L-Arginine, but I don’t want to pay the extra $$ for higher potency.I still experiment with supplements to see what works for me, but for the record, my other supplements include a man’s multi-vitamin, a B-complex, fish oil (2000), D3 (10,000), Vitamin C (1200), Tribulus Terretris, Tonalin CLA, Magnesium, Potassium.

Big Fan
I started taking these pills to stack with another supplement I began taking to increase my testosterone levels, as well as improve my circulation and general performance. The other supplement I’ve been taking includes Arginine, but as I needed to improve my blood circulation (both in my penis and in other parts of my body) I decided to amp up my intake of it. Jarrow’s brand has consistently been successful for me, so I opted to take an arginine supplement through them. The arginine has pumped up the nitric oxide in my body, therefore allowing blood to flow more freely. Not only has the combination of the two pill increased the voracity of my sexual performance, I also find that I’m feeling much better after workouts at the gym, and my stamina while in the gym is better too. If anyone has some of the same sorts of problems, I would recommend taking the Jarrow Arginine. If anyone is interested, the other supplement i take is called TruPlayer Elite Series: #1 Top Rated Male Enhancement Pills – Proven Testosterone Booster For Men – Get Results or Your Money Back!, and that seems to mesh well with the Jarrows by boosting my energy, stamina, and performance in both the bedroom and the gym.

Great Value Except If You Travel
For use at home, these are a great value and get the job done. I take it to help support my blood pressure. I wish I had read the reviews on traveling with them. As you can see by the photo, they completely disintegrated in the pill case. I had to rescue all my other pills from this powdery mess.

great product
I rated it 5 stars because I believe Jarrow is an excellent company. I’m selective about which brands I use & Jarrow is one I will pick over another, less expensive product.I’ve used this Arginine previously. I take it for increased circulation & to boost my immunity.Guys; if you’re looking for supplementation to enhance circulation & improve performance, may I suggest…L-Arginine….1,000-2,000 mg dailyPycnogenol…120 mg daily &Icariin (from Horny Goat Weed)…50-60 mg daily.Arginine provides your body with nitric oxide while Pycnogenol stimulates endothelial nitric oxide synthase to produce nitric oxide in the artery linings while at the same time Icariin acts to block the enzyme responsible for causing erections to subside, known as phosphodiesterase-5 (PDE5). It’s a synergistic effect where the supplements work together to provide a combination of health benefits which is a proven alternative to ED medications.I would recommend this product to other guys looking to enhance their circulation & boost performance; definitely.

The cap size is outrageously enormous
I’m not sure what the manufacturer was thinking. What human trout can swallow this gigantic, dry, rigged brick of a capsule?

アルギニン量は多い明記だが、効果は??なぜかわからんが、オーガランドのアルギニンの方が、効果が感じられると思う。あと、錠剤がでかすぎて、喉が痛い。アルギニン事態は、日本の有名所製らしい❗
