Questions & Answers

Below we have answered some commonly asked questions about this product.

What does the research show for l-arginine supplementation?

Researchers found that l-arginine supplementation may be conducive to lean tissue repair when consumed multiple times per day [1,2]

[1] K. Hnia, J. Gayraud, G. Hugon, M. Ramonatxo, S. De La Porte, S. Matecki, et al. L-Arginine Decreases Inflammation and Modulates The Nuclear Factor-Κb/Matrix Metalloproteinase Cascade In Mdx Muscle Fibers. Am J Pathol, 172 (6) (2008), pp. 1509-1519.

Why is this product so much cheaper than similar products on the market?

Many other brands incur a high degree of costs associated with producing products. It is not uncommon for a product to be produced by a third-party manufacturer and then shipped (or imported) to a wholesaler. The wholesaler then sells to a retail store, who on-sells to the customer. The end result is that often four separate businesses are taking profits at each stage (the brand itself, the manufacturer, the wholesaler and the retailer).

We take a very different approach which allows us to keep our cost structure down and we pass those savings on to you, without sacrificing product quality.

We have our own purpose-built manufacturing plant located in Sydney Australia and we sell directly to you. This eliminates all additional parties from the process, thereby eliminating a lot of unnecessary costs.

The significant cost savings we incur allow us to invest into high quality ingredients while still offering a significantly cheaper final product.

I haven't tried this product before. What if I don't like it?

Because we manufacture this product ourselves, we believe that the onus is on us to produce a high quality product that you're going to love.

That's why we have our 110% Guarantee. Basically if you try it and you don't love it, just reach out to us. You can receive a 110% store credit, or a full refund.

Easy to mix Easy to drink

Dissolves effortlessly in a glass of water.

Just add the small amount supplied by 1g spoon, just add water and drink.

Tastes a little salty but palatable.

This product was good from the start, I saw almost instant results from this product. Workouts improved very noticeably. It mixes well and the value for money is great. The only negative thing I have is the taste, it’s very bitter and overpowering. A flavoured product would make this 10/10 but now it’s still a 9/10. Will buy again!

The Best Choice for Nitrous Oxide Fans
By Brendan reviewed on 3/11/2018

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

I purchased 1kg of Amino Z unflavoured L-Arginine HCL and I have to say I am very happy with this product. I have been taking about 15g per day and I have experienced a noticeable increase in vascularity of the arms (especially the forearms), and I am lifting at my very best ever. I admit this is a large dose, but I bought a kilo for about $50, so why not? But be warned, unflavoured is a big decision, especially when you have the choice of 10 flavours.
