As long as suggested serving sizes are adhered to, no adverse side effects should be experienced. However, taking too much arginine may cause minor side effects such as upset stomach due to an accumulation of extra stomach acid. Arginine may also alter levels of potassium, which can be particularly dangerous for those with liver issues. Those who are taking ACE inhibitors and those that are taking diuretics or have kidney problems should not use arginine unless required to do so by a doctor. Women who are pregnant or nursing should not take this supplement. Those that have recently had a heart attack, those who are taking MAOI’s, Viagra or blood pressure medications should not take arginine either.


This product dissolves faster depending on how hot the water is. The taste is more pleasant than that of L-Arginine base or L-Arginine HCL; however, it is still best to mix with juice before drinking.

Customer Reviews

Aging issues
Getting older has its good points and also brings a few "issues". I have read articles about muscle wasting and decided to try L-Arginine to help with this issue. We order from bulksupplements due to the lower cost and that there are no additives to the supplements. I received this 100g package free and plan to order more in the future as I believe it is going to be a good addition to our daily workout drinks.*

Fantastic Supplement
I have tried MANY L-Arginine supplements in the past, mainly in the pill form you swallow pre-dosed and never had much success.

I recently purchased L-Arginine L-Pyroglutamate (250mg Powder) and it is absolutely a genuine product.

I take it about 45 minutes before a workout (And on off days in the morning) mixed in with my protein shake + milk (Still works), I take a SLIGHTLY larger dose than usual but within 20 minutes I feel warm, a little tingly and by the time I workout my veins are more visible. This means it is absolutely doing its job when other supplements I have tried haven't and that more oxygen and nutrients are going through to my muscles which will aid in protein synthesis etc ...

I am on low dose TRT for health issues and this absolutely helps with that. I also purchased Beta-Alanine from Bulk Supplements recently as part of my pre/post workout stack and also their Creatine.

A great product, shipped in a very timely manner. I will be buying again for a long time to come.*

Easier to run
My family and I started taking the L-arginine L-pyroglutamine and noticed a difference right away when running we weren't as winded as we normally are for the same workout. Love this stuff.*

Got this about a week ago. Today I felt like I got a better pump at the gym. I’m still looking for 3rd party reviews for bulk supplements but so far I’ve been happy with their products. *

First time trying this type of Arginine
This works great with the rest of my home-made wholesale pre-workouts. I can feel a greater pump when I'm working out and it gives me that bit of added motivation. Will definitely buy more when the time comes. *

L-Arginine L-Pyroglutamate
Based on my research, this is a superior product to regular L-Arginine and the pre-workout dosage is lower. Great price as always with Bulk Supps, I will continue to use this form of Arginine for pre-cardio and pre-weight training*

Pure product
I have yet to notice a difference from other forms of arginine I've taken for years, since I just starting taking this, but I selected this form of Arginine, to combine with Lysine, etc. for increasing hgh production. I love to buy from Bulk Supplements, knowing I get pure product at a great price.*

L-Arginine L-Pyroglutamate
This version of L-Arginine gives great pumps and increases the uptake of every other vitamin and amino acid that I take with it. Opening up your blood vessels makes it easier for your body and brain to grab all of the best vitamins and minerals from your blood stream--in abundant amounts!*

L-Arginine L-Pyroglutamate (APG) - 500g Pure Powder
This APG is the best quality and price that you can find. I am highly recommending this product. It gives me more energy during workout and when combined with Lysine, it also increases one's youth growth hormone. Great product. Very satisfied. Would buy it again.*

Great pumps while using this product. The powder mixes easily into water or juice. Overall, a great attribute to any pre workout stack.*

L-Arginine L-Pyroglutamate
L-Arginine L-Pyroglutamate Powder is the perfect and final addition to my Vascolator /NO stack. With the addition of L-Pyroglutamate my muscle bumps are sustained longer, harder and faster; my workouts are energized. Bulk supplements is my primary source for pure ingredients.*

On 4/4/2016 Derrick said...

Good choice
I liked the way this form made me feel in the gym, not sure if I'm feeling the benifits of the pyroglutimate? I will say I felt better results with the arganine HCL, but this supp mixes well, does give you the pump and nice vaso dialation. I will say in general for all supps from bulk supps is that there really has to be a change in the pouches. They don't close! And you waste the precious powder. Please fix, the quality is there for sure and for that I will continue to purchase from bulk supplements. *

L-Arginine L-Pyroglutamate Powder
I take this as a pre-workout. It gives me a great pump and makes me a lot more vascular during and after workouts. I also take it before bedtime as it releases more growth hormone helping me to recover from my workouts and burn fat. *

L-Arginine L-Pyroglutamate Powder
This is an excellent product with great price. After taking this product and L-Lysin together two times a day, my energy level has gone wild. Also this combination purported to be helping the youth grow hormone stimulation so you can stay younger looking forever. Don't believe miracle drugs, but, this combination is as close as it can be. Stay Tuned !!!*

Great product
I've purchased several products from BulkSupplements and I have to say that everyone of them has lived up to my expectations. I recently purchased L-Arginine L-Pyroglutamate and its one of my fav. My pumps are stronger and harder. One of the best things I find about these products is not having to worry about fillers or added sugars so I know what I'm putting in my body. Thanks BulkSupplements! *
