Types of Growth Hormone

Different brands of recombinant somatropin, used in sports pharmacology as an anabolic agent, differ from each other in a number of key parameters. From this article you will learn what kinds of growth hormone there are, and also what is included in this compound.

Differences between different brands of HGH

The degree of purity (homogeneity) of the drug;

The amount of active ingredient that is part of the Growth Hormone;

Cost;

The degree of security against forgery.

Composition of recombinant growth hormone

Recombinant somatropin, obtained using the genetically engineered E. coli strain, belongs to the group of polypeptides. The composition of the growth hormone is 191 amino acid residue (22 kDa). Due to a rather complex production technology, the spread in the degree of purity of sports products of different brands can reach 94-98%. Of course, the higher this index, the less in the preparation of ballast substances, and the more it is of better quality.

To identify the authenticity of the active component and obtain information about its purity, special analytical studies are used: exclusion chromatography, reversed-phase liquid chromatography, mass spectrometry. In accordance with international standards, 1 mg of growth hormone should be 3ME (permissible error ± 10%).

Types of HGH preparations

Until the mid-1980s, only natural (homologous) somatotropin was used in clinical practice, which was extracted from the pituitary body by corpses. However, due to the development of a sufficiently large number of negative consequences, this drug was banned from use and discontinued.

Currently, the industrial types of growth hormone are differentiated by the way they are obtained. These polypeptide drugs are divided into 2 groups:

The synthetic, containing in its composition 192 amino acid residues;

Recombinant (completely identical to natural GR), obtained by genetic engineering.

In sports pharmacology, recombinant somatotropin is used, which is the most high-quality preparation for injecting in its market segment. With the right dosage, it stimulates the growth of muscle mass, reduces the amount of subcutaneous fat deposits and has a powerful anti-catabolic effect.
