What are Peptides

manufacture

In our body, DNA is translated to RNA, which in turn is translated to peptides and proteins at the cell ribosomes.

it is a matter of length and complexity

The structure of Peptides and Proteins is a matter of length and complexity. Both consists of the 20 natural amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalaine, proline, serine, threonine, tryptophan, tyrosine, and valine. These structures are made of nitrogen, carbon, hydrogen and oxygen,, with variable side-chain groups. Of these 20, nine are considered essential: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. By essential we mean that these amino acids come from your diet, and not made in your body.

Peptides are by definition somewhere between 2 and 50 amino acids. More than that, one can refer to them as Polypeptides.

Proteins are longer and structurally more complex.

peptide function

Peptides have vital biological functions, as hormones and neurotransmitters.

As an example, human Growth Hormone (hGH) is a peptide hormone produced by the anterior pituitary gland that stimulates growth, cell reproduction, and cell regeneration. In actuality, it is a protein of 191 amino acids.

The amount of hGH produced is controlled by Growth hormone-releasing hormone (GHRH) or Growth hormone Releasing Factor (GHRF), which is produced by the hypothalamus. GRTH is a 44-amino-acid peptide.

Bremelanotide PT-141

bremelanotide PT-141 for libido

PT-141, also known as Bremelanotide, is a synthetic peptide that is used to treat sexual dysfunction in men and women. While Viagra and Cialis, which are PDE-5 inhibitors that work to increase blood flow into the penis, PT-141 is a melanocortin, which works at the brain to increase sexual desire.

Melanocortins are a group of peptide hormones which include adrenocorticotropic hormone (ACTH) and the different forms of melanocyte-stimulating hormone (MSH), and originate from the pituitary gland. The melanocortins bind to and activate melanocortin receptors.

Bremelanotide PT-141 was developed from Melanotan II, and was intended to darken skin pigmentation and induce tanning. However, during the initial testing, patients noted a pleasant side effect – that it caused increased sexual arousal.

Bremelanotide PT-141 is administered by subcutaneous injection, ideally where there are fat deposits. The only legitimate form of the peptide is injectable. Oral pills, nasal sprays, and creams have not been shown to be effective.

Given that everyone responds differently to Bremelanotide PT-141, effective dosages may vary. A two mg dose is generally effective for men and women, about one hour prior to sexual activity. Some studies suggest starting with a 1 mg test dose an hour before activity, and injecting an identical amount 30 minutes later.
