Testosterone and Growth Hormone are two powerful musclebuilding hormones. While Testosterone is a hormone from the androgen group that is secreted by the testes of males, Growth Hormone is released from the anterior pituitary gland. Stimulating the release of both of these hormones through proper supplementation (NITRO T3^® and Methyl TEST^™) is key to increasing muscle growth and strength.

FORM: Pills (capsules, caplets, li-caps, soft gels).

FUNCTION: Taken in the morning and before bed, these supplements boost natural testosterone and growth hormone levels. This aids in building muscle, increasing strength and recovery.

Testosterone FAQ

What is testosterone?

Testosterone is a naturally-produced hormone that is classified as androgen (male hormone). The production of testosterone is stimulated by luteinizing hormone (LH). LH stimulates the Leydig cells (found in the testes), which use cholesterol to produce testosterone. A healthy male will secrete between 4-9 milligrams of testosterone a day into the bloodstream. What’s important to note is that around 98% of the testosterone in the blood is bound to proteins, while the remaining is unbound or free.

What is the main difference between bound and unbound (free) testosterone?

The majority of testosterone is bound to Sex Hormone Binding Globulin (SHBG) as it travels in your bloodstream. Testosterone is not active when bound to SHBG therefore while stuck there it has no muscle-building effect. In order for testosterone to exert its anabolic (muscle-building) effects, it must be free from SHBG so it can bind to androgen receptors. This is why free testosterone is more important for athletes.

What is the androgen receptor?

The androgen receptor is located within muscle cells. Androgens (e.g. testosterone) bind with the androgen receptor and promote protein synthesis (growth) in the cell. Think of testosterone as a key, and the androgen receptor as a lock. Once they're brought together - you unlock one of the doors to muscle growth.

Growth Hormone FAQ

What is growth hormone?

Growth hormone (GH) is naturally produced by the anterior pituitary gland, which is found at the base of the brain.

What does GH do?

Once released, GH travels through the bloodstream and helps stimulate protein synthesis (growth) in muscle tissue, strengthen connective tissue, tighten skin and increase bone density. GH can also bind to fat cells and release stored fat for energy. In doing so, GH helps inhibit muscle tissue breakdown by preserving protein and glycogen (fuel) stores in muscle from being burned off for energy purposes. Additionally, GH can also enter the liver, where it can act as a catalyst for muscle growth, by stimulating the release of insulin-like growth factor-1 (IGF-1), a hormone that also helps build muscle.

How does IGF-1 lead to muscle growth?

When IGF-1 is released, it travels through the bloodstream and binds to the muscle cell. Once IGF-l binds to the muscle cell, it travels inside and through a series of events, stimulates the uptake of amino acids (the building blocks of protein) and inhibits the breakdown of muscle tissue.
