Here is a post I made just last night about insulin:
Insulin decreases blood sugar levels. It's is a 51 amino acid polypeptide produced by the beta cells of the pancreas in the Islet of Langerhans. Most insulin is synthetic with porcine rare in the U.S. Regular insulin is still available w/o a script and is mostly commonly used by athletes and bb's despite the risk of becoming a type 1 diabetic and DEATH. So stay away from it.
Regular Insulin:
Onset: 0.5hr - 1hr
Peak: 2-5hrs
Duration: 5-8hrs
There are approximately 6 insulins in widespread use in the U.S., humalog, novalog, nph, regular, ultra lente, and lente.
It's injected Sub-Q with a 100 unit syringe (0.3, 0.5 or 1ml) with a needle gauge of 26-31 and a length of 5/16 - 1/2"). Most common is 1/2".
The abdomen has the fastest rate of absorption, then arms, quads, and butt. It's important to rotate sites to prevent a sterile abcess and for better absorption of insulin.
Glucagon is the antidote for insulin. It is a 49 amino acid polypeptide produced by the alpha cells of the pancreas and is released in response to low blood sugar levels at approximately 70mg/dl. It is available in a pen form for diabetics to use in an hypoglycemic emergency to increase blood sugar levels.
Insulin is not available in oral form because it would be digested and therefore rendered useless. The oral pills that diabetics use are antidiabetic pills not insulin.
Normal blood sugar range is 70 - 100mg/dl.
Your insulin sensitivity is higher in the morning and after your workout but other than that it is NOT more sensitive throughout the day or evening.
