Finding a natural way to increase muscle growth is hard to find. Good thing there is IGF or otherwise known as Insulin-like growth factor. It is responsible for increasing the amino acid transport into the cells of the body, increasing glucose transport, increasing protein synthesis, as well as increasing RNA synthesis while decreasing protein degradation.

Once IGF is active, its behavior is different in most tissue types. It prevents insulin from transporting glucose across cell membranes so the cells will have to switch the burning of fat as an energy source. It also mimics the insulin present in the body. Because of this, it makes the muscles more sensitive; therefore, it lessens your chance of getting fat.


IGF-1 is a kind of peptide that is similar to the size and structure of insulin. It is roughly 70 amino acids long. IGF-1 belongs to the family of peptide that is linked with growth factors. There are many version of this peptide but the IGF-1 LR3 or Insulin Growth Factor Long R3 is considered to be 2 to 3 times more powerful than the regular IGF-1.

IGF-1 LR3 is very effective at building muscle and burning fat. It acts as a neuroprotector and a neuropromotor so mental functions like memory, reflexes and learning ability is enhanced. Moreover, IGF-1 LR3 is essential for the production of connective tissues and insures proper bone density.

By promoting nitrogen retention and protein synthesis, IGF-1 LR3 facilitates growth of muscles by hyperplasia and mitogenesis. In other words, it is not only responsible for making muscle fibers bigger, it also makes more of them. IGF-1 LR3 is an amino acid of the original IGF-1 in the human body but with the substitution of Arg for the Glu at position 3. It also has a 13 amino acid extension peptide that makes it more potent than IGF-1.

IGF-1 LR3 has a lower affinity made inactive by IGF binding proteins so it creates more potential activity in one’s body. This version is a clinically altered to avoid the binding of the proteins in the human body so it will have a longer half life of around 20 to 30 hours. Unlike most IGF-1, it is not as expensive. It is as sufficient for body building use like the media grade version. There are also receptor grade versions available but they are very expensive.

Almost all IGF forms are only supplied in lyphosized form, which means it is in powder state. Anything other than that should not be bought. IGF is a very delicate peptide so it must not be diluted before you purchase it. The diluents you will need for this IGF is a combination of a weak concentration of hydrochloric acid and a sterile buffer. Typically, the procedure in diluting the IGF-1 is not that difficult.


The most effective dosage of IGF-1 ranges between 20mcg/day to 120cmg/day. This dosage will determine how much money you will spending. Most body builders make use of the 20mcg/day and they are pleased with the results. It is most effective when administered under the skin and injected once or twice daily with the dosage you are using. Normally, the best time for injecting it is in the morning or immediately after weight training.

Don’t want to Inject IGF-1-LR3? Neither Do We! Here’s what we use instead…

However, if you don’t like injecting anything by yourself, you can choose to use Antler X. It is the highest-rated and by far the most important potent in this category. So much so that you do NOT need injections!! Also, it is FAR cheaper than in retail stores, so get Antler X online to save money!
