L Arginine Capsules - 2600mg L-Arginine with Added Glutamine - B12 and D3 for Normal Muscle Function (300 Vegetarian Capsules)

Update - continued to use for many months now and consistent results - definitely best brand I've used so far. Update - still an excellent product, provides a superb pump. Reason for my update is to say that I've definitely noticed a difference when I've note taken for a while, so decided to keep taking as part of my permanent daily routine. Excellent product, having been using this brand for some months now and is superior to many of the products I've used in the past. Delivers an excellent pump and you can really feel it working. Definitely one of the best L-Arginine products on the market. I continue to use this product as my first choice - I've used other brands of Arginine, and nothing is as good as this one.

This is an awesome product. I’ve been using L-arginine for 2 years, the first product equally as good but couldn’t get it again and let two I’ve bought just didn’t do the job! This one really does, gives me amazing levels of energy (in the bedroom as well!!!) and recovery from exercise is spot on. For a 54 year old male, I feel barely forty. Just hoping it doesn’t sell out and I suspect I will be stockpiling.

Great choice

I take 3/4 capsules with beetroot juice about 30 mins before I train 6 mornings a week – this is my first experience with Arginine and am not far from the end of the first container (just received my second order) and happy to report no side effects! This product really does seem to give me extra power, stamina and endurance, unless the whole thing is in my mind, but as a health freak in my 50s and been training for 30 years I can honestly say it has helped and with beetroot juice opening up the blood vessels for extra oxygen too – it's a well-liked boost for my daily morning workouts – so recommended!

Not good enough

I take 2 in the morning and 2 before going to the gym in the evening,also have a teaspoon of creatine before the gym and I definitely have seen improvement in size and strength and stamina in the gym,only been taking these for 4 wks but I have noticed I can go a little longer without burning out,don't get me wrong it's not like a steroid type boost but a boost all the same,I train mon to Fri n have sat n sun off,and managing to train each body part twice a wk n progressive over loading n its definitely working,and do believe that with these tablets n creatine n good clean diet you can't go wrong,would recommend giving them a try,they work for me but what works for 1 may not for another,just give them a try n see

Awesome

There has been a plethora of research into Arginine and according to the science, there are a variety of benefits which are too numerous to mention here. I use Arginine as I enjoy training hard in the gym and because it is a useful amino acid which directly produces nitric oxide via the nitric oxide synthase enzymes. I have found this supplement useful in combination with other supplements as the increase in nitric oxide when I am training seems to give me an edge in terms of energy, endurance and explosively. Now there will be the ones who will say that the science also shows these effects I mentioned to be unreliable in humans. And there may be merit in these scientific trials. However I do not hold much faith in these trials as they are usually conducted on non-athletes, so studies will show no net effects. However I can only state from my experience that this supplement works as long as you are absorbing it through the intestines to your body. Therefore you must have a clean diet and work hard to reap the benefits.
