Product Overview

Urso-X - High-Performance Bioactive Ursolic Acid

Urso-X is a new, natural anabolic compound that supports muscle growth, promotes muscle strength, reduces muscle catabolism and helps support fat loss.*

It’s very rare that a new discovery in the world of performance promoting supplements comes about. Urso-X is that new discovery.*

Very recent research has identified the key compound in Urso-X - ursolic acid - as a novel bioactive substrate that has powerful anabolic (muscle-building) and anti-catbolic (reduces muscle breakdown) properties.* This research also discovered that ursolic acid promotes powerful fat burning effects.*

Adding Urso-X to your training program may help you build more muscle faster, make greater strength gains more rapidly, and get leaner quicker.*

How Urso-X was discovered and developed…

A research team at the University of Iowa set out to find the elusive answer to supporting muscle mass under certain conditions. They first worked to identify the gene activity that occurs during the muscle weakening. Their research identified 63 different genes that changed during a fasting state in humans and another 29 genes that shift their expression during this catabolic state.

With this knowledge the researchers then compared those gene expression signatures to the signatures of cells treated with more than 1300 different bioactive molecules. Through a painstaking process of one by one elimination the researchers identified ursolic acid as a compound with effects that could counteract muscle catabolism and promote muscle growth.* They discovered the anabolic/anti-catabolic compound.

After identifying ursolic acid through the computer models, it was time to study the real-world effects. The researchers next gave ursolic acid to mice. This study clearly showed that ursolic acid had anti-catabolic effects and could help protect against catabolism and weakening as the computer models predicted.* The mice fed ursolic acid experienced less catabolism than the control mice (those not receiving ursolic acid) in the study.*

Muscle Growth - From Anti-Catabolic to Anabolic…

To follow up the first study researchers sought to confirm ursolic acid’s anabolic potential. When ursolic acid was added to the food of normal mice for a period of 5 weeks, it supported muscle growth.* A five-week course of ursolic acid was suggested to promote up to 15% greater muscle growth than the control mice not consuming ursolic acid.* And the mice getting the ursolic acid grew measurably stronger than the control mice.* Scientists confirmed through muscle biopsies and microscopic analysis that actual muscle fiber thickening had occurred - muscle hypertrophy. Bigger, stronger, faster.*

The Anti-Catabolic Science…

Digging deeper into the science, the researchers discovered that ursolic acid decreased the activity of the catabolic genes MuRF-1 and Atrogin-1 in the muscle cells.* These are two of the most potent genes associated with catabolic (muscle-breakdown) activity in muscle. Ursolic acid appears to have an effect on reducing catabolic activity in muscle cells by decreasing the activity of the genes responsible muscle breakdown.*

The Anabolic Science…

The researchers also discovered that the activity of the gene for IGF-1 (Isulin Growth Factor 1) increased and the concentration of IGF-1 in the blood also increased. Ursolic acid appeared to support the activity of the gene and blood level concentrations.*

Ursolic acid helps support the key anabolic hormones responsible for muscle growth.*

Another key anabolic effect centers around ursolic acid’s effect on molecular signaling molecules. Ursolic acid “switched on” the receptors for IGF-1, Akt and S6K. This molecular signaling activity supports an increase in protein synthesis and cell proliferation.*

Ursolic acid is a bioactive compound that literally works through multiple pathways to help reduce muscle catabolism and support muscle growth.*

And it doesn’t stop there…

In the studies ursolic acid also supported healthy body composition;, and even promoted healthy fasting glucose levels already within normal range.* All of these are positive effects for helping support healthy body composition.*

So what does all this science mean for you…

Urso-X just might be the most significant muscle-growth promoting compound to come along in decades.* It certainly has serious scientific credentials that are sure to grow in volumes as more in-depth research is conducted. But you can reap the muscle-supporting rewards now!*

A natural substrate found in several herbs and fruits, Urso-X works on multiple genetic signaling pathways that promote the biological activities for lean muscle growth, increased strength and supporting fat loss.*

Adding Urso-X to your training program will put you on a sure-fire path to supporting muscle growth, strength, and fat loss.*

How to take Urso-X…

Each capsule of Urso-X contains 75 milligrams of bioactive ursolic acid. Take two (2) capsules three (3) times a day with meals. Continue for 6 weeks followed by 1 to 2 weeks off. Repeat cycle.

Been using this product for about 7 weeks now as per recommended. I am in the process of leaning out for a competition and have noticed I am losing the fat and keeping the muscle. Great product and I ordered my second bottle already. Only reason I am not giving it a 10 out of 10 is because I know that the proper diet and regimented training for during a contest preparation is key and not really the supplements. Nevertheless, I will give this a try in my off season, when I am able to eat more calories and see what the gains will bring.

I'm almost finished with my first bottle. How do I like it? I like it enough that I ordered a replacement so I won't run out! I've seen a reduction in fat and an increase in muscle development and strength. AST has some of the best supplements out there. There were no jitters or any negative side effects from using this on a regular basis.

I've been using this product for about three weeks now with proper diet and training and I've notice nothing. So take it from me don't believe the hype and save your money.

The fact of the matter is alot of products out there do not work. However this is a fantastic product. It worked extremlly well for me. I felt it working within my first training session. I naturaly have always had great pumps during my workout and blow up like a ballon but taking this AST Urso-X has made my pumps go through the Roof! Of course this supplement is meant to go with proper nutrition for it to work like it was designed to work. Dont expect to feel it work if you eat crap like Cheeseburgers, fries, and pizza. But with proper nutrition is a absolute great supplement.
