Humulin M 70/30 (Cart) Insulin is a highly anabolic and powerful hormone produced by all human beings and is essential to a well-functioning individual. Although produced naturally by the human body, insulin is often administered exogenously to those suffering from diabetes. Some performance athletes also use it in an effort to grow lean tissue. However, off-label use can be potentially fatal; extreme caution is advised.

Although all human beings naturally produce insulin, exogenous insulin first appeared in the 1920’s. This was not a synthetic model, but rather extracted from the pancreas of dogs and latter cattle and pigs. While purity was a major issue of concern, the use of exogenous insulin was highly praised as it would save the lives of numerous individuals. Diabetes without insulin treatment can easily be fatal, and while animal extract isn’t pure any impurity issues were considered worth the risk when death was the alternative.

However, by the 1970’s purity issues had been greatly resolved, and in 1975 Ciba would introduce the first batches of synthetic insulin to the market. A few years later in 1982, the synthetic version would be perfected even more with the introduction of Humulin-R, which is a perfect copy of human insulin and approved by the FDA.
