Peptides what is it?

What are peptides?

Peptides (Greek πεπτος - nutritious) is a family of substances, the molecules of which are constructed from the residues of α-amino acids connected in a chain by peptide (amide) bonds. These are natural or synthetic compounds containing tens, hundreds or thousands of monomeric units - amino acids. This class is very diverse and performs a variety of regulatory functions in the body. Within the framework of this article, we will consider only those peptides that are used in sports to correct physical indicators.

At present, peptides, which are growth hormone stimulants, are increasingly on the market. We will name the most popular of them.

From the Grelin group (GHRP): (create a pronounced peak of the GH concentration immediately after administration, regardless of the time of day and the presence of somatostatin in the blood.)

GHRP-6 and Hexarelin

GHRP-2

Ipamorelin

From the Hormone Growth Hormone Releasing Group (GHRH): (administration to the body causes a wave-like rise in concentration that will be weak in the hours when natural GH secretion is reduced by somatostatin, and high during natural increase in GHR concentration (for example, at night) .In other words, GHRH Strengthens the secretion of GH without disturbing the natural pulsed curve.)

GRF (1-29) Sermorelin

CJC-1295

HGH Frag (176-191) - a fragment of growth hormone (fat burner)

Benefits of peptides

Many people have questions, why use new peptide substances if there is an artificial growth hormone? The answer is simple - peptide stimulants have several significant advantages:

- Peptides are much cheaper than growth hormone. The cost of a similar course will be several times lower.

- Different mechanisms of action and half-lives can manipulate the concentration curve, achieving optimal anabolic response.

- A different effect on hunger and metabolism, allows you to give preference to certain substances.

- At the moment, the production and distribution of peptides is not regulated by law, so they can be ordered online without fear.

- Quickly and without a trace are destroyed, so you can not be afraid for doping control.

Peptides, as well as classical GR, can be easily verified for authenticity. To do this, it is sufficient to pass tests for the level of somatotropin in the plasma after the administration of the drug. However, the time through which it is necessary to pass the analysis is usually not more than an hourū

Other peptides:

Melanotan 2 - a means for tanning and strengthening libido

Bremelanotide PT-141 - enhances sexual desire and erection

Gonadorelin - stimulates the secretion of testosterone

TB500 - for the treatment of injuries and joint repair

SARMs (selective androgen receptor modulators)

Growth hormone stimulants

Insulin-like growth factor

Mechanical growth factor

Reviews of scientists about peptides

Studies have shown that peptides-stimulators of growth hormone secretion (GHRP), as well as other non-peptidic substances that increase secretion, really affect the production of growth hormone. What many physical parameters of an athlete depend on, for example, the amount of muscle mass or the total amount of fat.

These observations formed the basis for the creation of food additives - growth hormone stimulants (for example, amino acids, pituitary peptides, Macuna pruriens, horse beans, choline alfoscerate, etc.). At the current time, there is evidence that peptides-stimulators of growth hormone secretion and some non-peptidic substances can increase the level of growth hormones, as well as insulin-like growth factor (IGF-1) both at rest and during exercise.
