6-Compounds, Big Doses, Study Backed Ingredients - Major Bulk is here!

Six efficaciously dosed ingredients with a pharmaceutical grade bio-availability agent all bottled up to assist you in building solid natural muscle!  

The formula for Major Bulk was carefully crafted to make sure the ingredients worked together synergistically to achieve the best results. 

One of those ingredients, Phosphatidic Acid, was able to help produce 5.3 lbs of muscle gains on just 3 days of training in studies with up to a 600% increase in mTOR signaling. Another, Maral Extract, was as able to increase working capacity by up to 15% after just 20 days of use. Thirdly, Ursolic Acid, boasted 413% more muscle gains and 5 lbs of fat loss in a 4-week university study.

 What's Inside Major Bulk?

Phosphatidic Acid: (PA) is a phospholipid which is a major constituent of cell membranes but more importantly, it helps to spike mTOR signaling by over 6 times which enhances the effects of weight training. Multiple studies have been conducted on PA, based on the double-blind placebo-controlled study at the University of Tampa users packed on 5.3 lbs of muscle (double the gains of the placebo group) as well as they increased their strength on the leg press by 60% more than the placebo group in just 8 week on with just 3 days of training per week.

Ursolic Acid: Belongs to a category of compounds known as pentacyclic triterpene acids. Research shows this unique substrate to be a potent anabolic – anti-catabolic compound. Research also displayed that it inhibits skeletal muscle atrophy and the expression of IGF-1 signaling. Additional research has shown promotes muscle hypertrophy and may reduce fat gain. One recent university study comprised of 14 athletes realized a 413% greater increase in lean mass compared to the placebo group as well as and 5lbs of fat loss.

Maral Extract 4:1: Also known as Russian Leuzae, was used by Russian military during WWII as a natural remedy to help soldiers recover their strength from battle. This compound is a plant source of Ecdysteroids, a class of compounds that exhibit anabolic properties without interacting with androgen receptors (as do the common androgenic steroids known to bodybuilders). These ecdysteroids go directly to the muscle cell to activate the Akt-PkB pathway causing a variety of responses including protein synthesis, increased glucose absorption, and enhanced gene expression.

HICA:  a metabolite of the amino acid leucine that promotes increased protein synthesis and decreased muscle protein breakdown. It does this by neutralizing catabolic muscle wasting products that are created during high intensity training. HICA works to support gains in mass and strength while promoting accelerated muscle recovery.

Laxogenin: Derived from plants, this ingredient is essentially a building block which your body uses as a blueprint to create its own steroids. Laxogenin has been compared to Anovar and supports increased protein synthesis and nitrogen retention while promoting other anabolic effects such as increased strength, muscle endurance, muscle recovery, and lean muscle mass. Additionally, Laxogenin aids in controlling the stress hormone cortisol, which when out of balance increases fat and muscle wastes.

So far so good

After 1 1/2 weeks of taking this product, I feel as though there has been an increase in strength, and has contributed to how solid I am....f**kin' GRANITE!!

I ran two bottles with increase in caloric intake and worked out 4x a week, pushing heavy. After 2 months I wanted to leave a review. I added dense solid muscle. Most noticable in my chest and shoulders and arms. My suit jackets are bit a tighter unfortunately but its all for the gainz, so I can't complain.
