Insulin is considered to be an effective, potent anabolic hormone that can trigger natural ability of the human body to open its stores along with shuttling nutrients to the respective storage areas (body organs and parts). By triggering maturation of the satellite cells, Insulin helps users to gain more out of cells that otherwise do not contribute to muscular growth of the body. These results are attained when supply of insulin is complemented with resistance exercises and androgens.

The chemical formula of Insulin is C256H381N65O79S6 and its molecular mass is 5801.6 g/mol at the base.

By initiating a cascade of cellular events resulting in up-regulation of cellular nutrient content, Insulin promotes high anabolic effects or osmotic responses or improvements in terms of water and nutrients in the body. In addition to all these benefits, Insulin also promotes the processes of glycogen and fatty acid synthesis along with improving esterification of fatty acids and uptake of increased potassium levels. Insulin is equally effective in minimizing the levels of lipolysis, gluconeogenesis, and proteinolysis so that the body can deliver more and better without any fail.

In the world of professional sports such as athletics and bodybuilding, insulin is used to bulk up. This drug offers an approximate active life of 1.5-3 hours. In the world of healthcare, insulin is used to treat patients affected by type 1 or type 2 diabetes mellitus.

The recommended dose of insulin is 1 I.U. per 15-20 pounds of lean bodyweight. This dose can be increased by 1 I.U. after each consecutive post-workout application. The doses of insulin are taken in an injectable form and abdomen is the most preferred injection site though the injections can be administered on different spots to avoid pain at injection sites. When abused or of a low grade, Insulin can lead to side effects such as headache, nausea, tiredness, and tremors.
