Protein Peptides
Peptides are short polymers of amino acids linked by peptide bonds. They have the same peptide bonds as those in proteins, but are commonly shorter in length. The shortest peptides are dipeptides, consisting of two amino acids joined by a single peptide bond. There can also be tripeptides, tetrapeptides, pentapeptides, etc. Peptides have an amino end and a carboxyl end, unless they are cyclic peptides. A polypeptide is a single linear chain of amino acids bonded together by peptide bonds. Protein molecules consist of one or more polypeptides put together typically in a biologically functional way and sometimes have non-peptide groups attached, which can be called prosthetic groups or cofactors.
Protein peptides are the preferred method for the body to absorb nitrogen into the muscles because the proteins can be absorbed intact. In fact, peptides are absorbed over 200 percent faster than free-form amino acids or whole protein molecules. The faster protein is absorbed in the body, the more it promotes protein synthesis – a key component in muscle development. When the body breaks down proteins, it breaks them down into peptides, which in turn creates nitrogen in the bloodstream. Over 70 percent of nitrogen found in the bloodstream is in peptide form. Also, protein peptides made from whey are over 65 percent better at retaining nitrogen than regular whey. Other valuable characteristics of peptides are that it helps weight loss by stimulating the brain center that tells the body that it is full. Peptides stimulate Insulin Growth Factors, which develop muscle tissue. Peptides are also found to aid gastrointestinal and liver function.
MGF
MGH is a protein peptide that activates the process that repairs muscle damage. When muscles are worked out, or damaged, MGH triggers the metabolic agents in the body such as IGF-1 to repair and replace damaged muscles. Natural MGH declines with age and is a major cause of muscle tissue decreases as we grow older. MGH in clinical doses has shown remarkable results for not only muscle repair but new muscle growth as well.
CJC-1295
CJC-1295 is a tetrapeptide that was developed to aid in weight loss. It is a growth hormone releasing hormone (GHRH) that has a longer half-life in the body than other GRHRs.
PT-141 (Bremelanotide)
PT-141 is a heptapeptide developed from Melantonan II. It has been studied for a variety of applications, including cosmetically as a sunless tanning agent and as a sexual dysfunction drug that could treat erectile dysfunction in men and arousal dysfunction in women. PT-141 was found to have some unwanted side effects on the circulatory system (high blood pressure) and further testing has been delayed.
Hexarelin
Hexarelin is a hexapeptide that is injected and stimulates the pituitary gland to produce growth hormone (GH). It also stimulates IGF-1 response, making it ideal for muscle mass and strength increases as well as fat loss. Because Hexarelin stimulates natural GH, it is often used after a cycle of HGH to avoid shutdown of natural GH production.
ALCAR (Acetyl-L-carnitine)
ALCAR is an experimental acetylating agent that modifies protein structures. It is being tested for its unique quality of improving brain function and as a possible cure to diseases such as Alzheimer’s and dementia.
IGF-DES
IGF DES is a potent Insulin Growth Factor peptide that is fast-acting and has the ability to act with IGF receptors even after they’ve become damaged by lactic acid during workouts. It also seems to have a longer half-life than its counterparts like IGF-1 or IGF-LR3.
Follistatin 344
Follistatin 344 is a peptide that inhibits myostatin, the chemical in the body that regulates muscle growth. When the body produces myostatin, it tells the muscles to stop growing, which is why inhibitors like Follistatin allow bodybuilders to grow larger muscles. Reports on this peptide vary and there are complaints that it adversely affects the tendons.
Triptorelin
Triptorelin (aka Decapeptyl, Diphereline, Gonapeptyl, Trelstar and Variopeptyl) is a decapeptide that was developed to help treat prostate cancer. It is in a class of drugs called gonadotropin-releasing hormone agonists (GnRH agonists). The result from taking Triptorelin is a gradual reduction of testosterone in the body, which is why the best use for this peptide is part of a post-cycle therapy where you need to reduce testosterone before it aromatizes into estrogen.
PEG-MGF (PEGylated Mechano Growth Factor)
PEG-MGF is a peptide hormone that increases the stem cell count in muscle tissue. Stem cells allow the muscle to heal and to grow in number and size. The PEG, or polyethylene glycol, is attached to the MGF to make the peptide last longer in the body by increasing its half-life. This allows the MGF molecule to act more consistently on the muscle tissues, providing greater results.
Melanotan II
Malanotan II is a synthetic analog of the body’s natural melanocortin peptide hormone – the alpha-melanocyte stimulating hormone (a-MSH). It is being developed as a tanning agent for skin and as a drug to treat sexual dysfunction in both men and women.
GHRP-2 (Growth Hormone Releasing Peptide-2)
GHRP-2 is a hexapeptide that acts on the pituitary gland to release Human Growth Hormone (HGH). This peptide has a strong anabolic effect and creates strong muscle gains and weight loss. Besides boosting HGH levels, it also has a strong effect in boosting IGF-1 levels. This peptide works best in conjunction with HGH because it stimulates the natural HGH levels making it less likely that synthetic HGH will shut down the pituitary gland’s natural production.
Ipamorelin
Ipamorelin is a pentapeptide that acts on the pituitary gland to produce Human Growth Hormone. An increase of HGH levels builds muscles and burns fat at incredible rates. Studies have shown that there is little long-term effect that Ipamorelin has on the pituitary gland’s ability to naturally produce growth hormones.
IGF-1 Long R3
IGF- 1 Long R3 s an insulin-growth factor peptide that increases amino acid transport to cells, increases glucose transport, increases protein synthesis, decreases protein degradation and improves RNA synthesis.* Unlike regular IGF-1, the Long R3 version doesn’t easily bind to the IGF binding proteins that inhibit the biological actions of IGFs.
GHRP-6
Growth Hormone Releasing Peptide-6 (GHRP-6) is an amino-acid peptide that triggers the body to release growth hormone. Growth Hormone burns fat and increases muscle strength and mass. GHRP-6 has the distinct characteristic of being a Ghrelin antagonist. Ghrelin is a chemical in the body that helps store fat, which makes GHRP-6 a great peptide to take to get lean.
HGH
Human Growth Hormone (HGH) is a synthetic version of the natural growth hormones produced by the pituitary gland. Growth hormones tell the body to build muscle and burn fat in people during their puberty years. Growth hormone production slows as we age and is a major cause of how the body looses strength in old age. There are many types of HGH on the market today and is available by prescription and on the black market.
HGH Fragment 176-191
HGH Fragment 176-191 is a piece of the Growth Hormone chain of amino acids – the part of the chain from amino acid number 176 through the amino acid number 191. It is believed by the developers of this peptide that the fragment of amino acids is responsible for the fat burning properties of HGH. They were attempting to isolate a stronger formula that targeted only fat burning to market as a weight loss drug.
