What it is

A peptide hormone normally produced by the pancreas to regulate blood sugar. Used in advanced bodybuilding stacks to drive nutrients into muscle cells. Available in rapid-acting and longer-acting forms. This is not a recreational compound. It has killed experienced users.

What it does

Dramatically increases nutrient uptake into muscle tissue. Promotes rapid mass gain when combined with HGH and anabolic steroids. Works by forcing glucose and amino acids into cells, which can accelerate muscle growth but also fat storage if nutrition is not precisely managed.

Typical dosages

Dosage information is deliberately not provided in detail here. Insulin dosing errors can cause coma and death within minutes. This compound exists in this guide for awareness, not as a harm reduction pathway. If someone is determined to use insulin, they must seek direct guidance from someone with verifiable experience and have immediate access to fast-acting carbohydrates at all times.

These figures reflect commonly reported usage in harm reduction communities. They are not recommendations. There is no safe dose of anabolic steroids for non-medical use. Start low and monitor your health through blood work.

Side effects

Hypoglycaemia (dangerously low blood sugar), which can cause confusion, seizures, coma, and death
Fat gain (almost inevitable without extremely precise nutrition timing)
Insulin resistance with prolonged use
Water retention
Lethargy and drowsiness

Specific risks

Death: insulin overdose causes hypoglycaemia, which can lead to coma and death within minutes. There is no margin for error. This has killed experienced bodybuilders
Type 2 diabetes: long-term exogenous insulin use can cause insulin resistance and type 2 diabetes
No reversal without preparation: if hypoglycaemia occurs and fast-acting carbohydrates are not immediately available, the consequences can be fatal before emergency services arrive
Unpredictable response: individual sensitivity to insulin varies enormously. A dose that is manageable for one person can be lethal for another

What to watch for

Shaking, sweating, confusion, dizziness, rapid heartbeat (signs of hypoglycaemia, requires immediate fast-acting carbohydrates)
Blurred vision or difficulty concentrating after injection
Never use insulin alone. Always have someone nearby who knows what you have taken and what to do
Keep fast-acting carbohydrates (glucose tablets, juice, sweets) within arm's reach at all times
Fasting blood glucose trending upward on blood work (sign of developing insulin resistance)

Other compounds

Testosterone

Lower/Moderate Risk

The base of almost every steroid cycle. Testosterone is the primary male sex hormone and the most commonly used anabolic steroid.

Trenbolone

Extreme Risk

One of the most powerful and dangerous steroids in common use. Extremely potent but with a severe side effect profile that makes it unsuitable for most users.

Anavar (Oxandrolone)
