Bodybuilding Peptides for Muscle Growth

How do we increase / gain muscle mass?

Increasing muscular size and strength occurs by making improvements to the neurological control of the muscle cells by way of the brain and spine.

Bodybuilding Peptides to Increase Muscle Growth

  • Neurological control is improved through frequent and high-intensity repetition of the particular movement leading to changes in nerve connections and activation thresholds.
  • All bodybuilding enthusiasts know that you can increase muscle growth by triggering mechanical and metabolic stress.
  • This muscle growth occurs primarily by the production of extra contractile proteins within the muscle cells, a process called muscle hypertrophy.
  • There is also a small increase in the number of muscle cells, a process called hyperplasia.

Muscle Cell Structure

Muscle cells are among the largest individual cells found in the body. They contain mesh-like proteins that have the ability to slide past each other resulting in a shortening of the muscle cell (fibre). Considering the size of a muscle cell, there needs to be a large number of nuclei which contain DNA code to support the cellular functions.

The Distinction between Peptides and Steroids:

Apart from being a natural and much safer option to steroids, peptides:

Grow new muscle cells i.e. increase the number of muscle cells, resulting in greater:
  • Shredded muscle
  • Lean muscle
  • Quality muscle
Steroids increase the size of already existing muscle cells, resulting in:
  • Greater bulk
  • Less definition
  • Low quality, artificial, temporary muscle

Bodybuilding Peptides – Triggering the Release of IGF-1 into the blood

One of GH’s main effects, is to trigger the liver to produce and release insulin-like growth factor-1 (IGF-1) into the blood. GH also triggers IGF-1 production within cells. IGF-1 has primarily proliferative effects, which means it stimulates cell multiplication (hyperplasia) as well as an increase in the size of the cell (hypertrophy) (Adams 2002, Munteanu 2004, Zingg 2004).

Growth Hormone levels in the blood are controlled by a negative feedback mechanism. GH and IGF-1 levels in the blood inhibit GHRH release from the hypothalamus, increase SST release from the hypothalamus, and decrease GH release from the pituitary gland(Patrie 2004, Veldhuis 2001). These changes decrease GH production until blood levels decrease and the negative feedback is removed.

HIGH INTENSITY TRAINING AND ITS EFFECT ON MUSCLE GROWTH

Bodybuilding and weight training will stimulate more contractile protein. Contractile protein will then need further muscle nuclei (myonuclei) to function property. The inactive stem (or satellite) cells around the muscle fibre then has the ability to be stimulated to fuse with the muscle fibre. It can then differentiate into myonuclei, and help produce and support the additional contractile proteins. High intensity training is highly effective at both stimulating increased contractile protein, alongside supplying myonuclei to maintain cellular function. Maintaining the correct GH and testosterone levels also have the ability to do this.

GH LEVELS AND INCREASING MUSCULAR GROWTH

As we age, our growth hormone (somatopause) and testosterone (andropause in men) levels decline. While both increase briefly after exercise, growth hormone levels can be further elevated by bodybuilding peptides designed to stimulate GH release from the anterior pituitary.

Bodybuilding peptides ordinarily fall into one of two categories.

  • Growth Hormone Stimulating Peptides
  • Growth Hormone Releasing Peptides

Growth hormone has the additional benefit of stimulating connective tissue growth around the muscle (fascia, ligaments, tendons). This improves the connective tissue’s recovery and repair after high-intensity training, and decreases the risk of overuse injury (tenosynovitis, tendinosis).
