Product Overview



Muscletech Essential Series Platinum L-Carnitine 1500.




The skin stretches. The muscle aches. The veins pop. The muscle bellies start to swell, you know the feeling. When the veins are bulging out, the muscle looks full and the skin over your muscles gets very thin. It’s the greatest feeling – the natural high you get from hitting the weights hard. It’s called the Pump, and for years bodybuilders and other athletes have relied on L-arginine to enhance these muscle-swelling pumps to feed their muscles the nutrients they need to perform, recover and grow bigger for sleeve-stretching pumps that are absolutely unreal!*

New Platinum 100% L-Arginine delivers a full 1,000mg dose of L-arginine for rapid uptake and dispersal in your body.* Flooding your body with this powerful nitric oxide precursor primes you for extreme pumps, enhanced blood flow and nutrient delivery during exercise!*


When you train, your body releases calcium in the endothelial cells that line your blood vessels. This causes the enzyme nitric oxide synthase to create nitric oxide from available L-arginine. As the nitric oxide leaves the endothelial cells, the blood vessels relax, causing vasodilation. By supplying a massive dose of L-arginine to your body, Platinum 100% L-Arginine helps trigger nitric oxide production for superior vasodilation effects and massive muscle pumps.*


For over 20 years, MuscleTech has been synonymous with results – this is the reason they’re the #1 selling body building supplement brand in America. Essential Series products are staples for every athlete, with no fills and no fillers – just products you can tryst packed by the best brand in sports nutrition.

there's no noticeable change, I take it because I know it increases the availability of the NO precursor, nothing else


My pump was rediculous after about 5 days of taking this. Noticed a very big difference.


Noticed an increase in vascularity with this product after about a week. I would recommend MuscleTech's Platinum 100% L-Arginine to anyone looking for a simple supplement that works to increase pump.

Just got this and wanted to know if I should take it on non workout days? Also I feel like taking 2 capsules is a lot, would 1 capsule be effective?

No written review.

I am hooked on this product. I feel the pump, I feel like an animal after I take this, I can lift more and heavier weights. Will buy again.


I take 1 serving before training and muscles swell very nicely, enjoyed the harder erection too.


I feel a lot more energy with each rep! works great!


This is a great nitric oxide precursor. At the moment, I only take before my workouts (with results that speak for themselves), but plan on adding to my daily supplement regime and can't wait for the results.


I have no complaints, this is perfect for people who want to get mass because you'll feel the pump during your workout..even though I don't have a lot of veins showing, I like when I see the one of my arm get cool.


Great product. Will def buy again


First time trying this product and I am hooked! Definite increase in pumps and a lot of vascularity


I am on my first bottle of this product and already have seen the results that is states. I do seem to get a much better pump with this and the pump seem to last longer in the day after my workout. I also think this product works great to open the vascular system to help get my post workout supplements into my system faster. Again Muscletech delivers on a great product.


I was happy to get to try this out, I'm actually using it for something other than most of you because arginine is said to be beneficial for helping females with balancing hormones back out when they've lost their cycle, which is my current circumstance. No bad effects noticed, been taking it daily with vitamins.


This supplement gives me a great pump during my workouts! It is simple to take and the pumps that you get are insane! I recommend this to anyone who is in to weight training and is looking to maximize their pumps!
