High-performance Pre-workout and Advanced Nitric Oxide Supplement

Hi-Tech's AMP3D™ Pre-workout and Advanced Nitric Oxide Supplement utilizes a Hi-Tech proprietary compound –– Citrulline Silicate (Nitro Rx®) –– which is the strongest Nitric Oxide compound ever developed! AMP3D™ Utilizes the Novel Approach called Arginase Inhibition! This Hi-Tech exclusive technology leaves an abundance of L-arginine uncompromised in the muscle pool to create a wealth of NO, leading to maximum muscular vasodilation. AMD3D™ Pushes the Boundaries of Nitric Oxide Production! AMP3D™ is designed to take advantage of the pre-workout window of opportunity to accelerate muscle growth by creating a feeding pool flourishing with compounds that improve training intensity, work performance, and set your muscles up for more rapid recovery and enhanced muscular growth. 

Supplement Facts

The Science

Nitric oxide (NO) sports nutrition has become the largest sports nutrition product category. Yet, despite dozens of "advancements" in NO supplementation, traditional NO sports nutrition still remains flawed for one fundamental reason. This flaw can easily be detected by simply inspecting the formulations in NO products across-the-board throughout the sports nutrition industry. The formulations in these products demonstrate a failure on the part of other supplement companies to understand and address the most efficacious means to serve L-arginine up on a platter for the production of NO, which is to incapacitate the arginase enzyme. Arginase is the enzyme that breaks down arginine, which is a problem for NO supplements because arginine is the source of NO production. With the exception of Hi-Tech Pharmaceuticals, no other supplement company has figured out how to tackle the arginase problem head-on... to take arginase out of the NO equation!

Many novel scientific discoveries have been encountered while in search of unrelated applications. Hi-Tech initially developed S-(2-boronethyl)-L-cysteine HCl (BEC) as a sexual stimulant when perfecting its formulation for Stamina-Rx®, only to discover that this compound has amazing muscle-building properties. AMP3D™, on the other hand, utilizes a "straight up the middle" approach by blasting high dosages of L-arginine into the bloodstream along with a highly potent, arginase inhibitor that bonds to arginase enzymes, which render these enzymes incapable of preventing L-arginine from uniting with NOS enzymes on their way to creating NO. Hi-Tech utilizes BEC, the novel arginase inhibitor in AMP3D™ to flank the high dosage of L-citrulline, citrulline silicate, agmatine silicate, and arginine Hcl and to take arginase head-on by rendering it useless. This leaves an abundance of L-arginine uncompromised in the muscle pool to create a wealth of NO, leading to maximum muscular vasodilation

Although everyone in the sports supplement world is talking about NO and pre-workout supplements, very few people really understand much about it. When the amino acid L-arginine is delivered to the endothelial cells of the inner layer of arterial walls, nitric oxide (NO) is formed via the enzyme nitric oxide synthase (NOS), which means that L-arginine is a precursor of NO. Increased levels of NO cause vasodilation (widening) of blood vessels. This leads to increased blood volume (known in the bodybuilding world as "the pump"), which is sought after by bodybuilders to optimize the grueling exchange of oxygen, glucose, amino acids, creatine, waste byproducts of muscular contraction, etc., that takes place both into and out of muscle during and immediately after intense muscular contraction.

AMP3D™ utilizes the dynamic duo of Citrulline Silicate (Nitro Rx®), which is the strongest Nitric Oxide compound ever developed couple with S-(2-boronethyl)-L-cysteine HCl (BEC), which is a novel arginase inhibitor that allow you to get INSANE “PUMPS” along with some of the most intense workouts you have ever had due to Hi-Tech’s proprietary High Stimulant blend. It took us 10 years to bring a truly revolutionary pre-workout to market but try AMP3D™ and you will see what all the fuss is about!

Two Filters, Quick and Easy
Size: 16-23 Tacoma, Size: 16-23 Tacoma
The RVgolf Engine+Cabin Air Filters Kit for the Toyota Tacoma V6 comes with two air filters. There is a cabin air filter that fits nicely into the compartment accessed through the glove box and an engine air filter that dropped in easily in the compartment under the hood. Replacement of both filters was easy, didn’t require any tools, and it took more time to empty and replace the items in the glove box than it did to replace both filters. The Toyota dealership quoted me $80 to replace the cabin air filter only. I replaced both filters for less than $30. The filters felt like they were good quality. The engine air filter is multi-layered, with a thin foam layer to keep larger debris from blocking the finer paper filter. The cabin air filter said and looked like it had a carbon layer to absorb smells. The only concern I had was size. After I had replaced both filters I went to slide the engine air filter I replaced into the RVgolf box to throw it away. The engine air filter I replaced would not slide into the RVgolf box. It was too big. After driving for a few days and a couple of hundred miles, I popped the hood and checked the fit of the engine air filter. The fit looked perfect. See attached photos.

Fits 2019 accord (gas engine)

Dealer was going to charge almost $200 to change both of these filters in my 2019 accord. These filters fit perfectly and of same quality as the dealer product. Easy to install, saving me lots of money.

Great quality and Easy to install
Size: 18-22 Accord
As someone with zero experience changing air filters, I was honestly surprised at how easy this was. The fit was perfect for my 2010 Honda Accord Sport, and both the cabin and engine air filters installed with no issues at all. It even came with clear, easy-to-follow instructions that made the whole process stress-free. Saved myself money from going to the dealership, and my car is running great. Definitely recommend for beginners wanting to do a simple DIY maintenance job.
