Genotropin 36 IU (Pfizer) 

Here is a table summarizing key information for Genotropin

* The 12 mg corresponds to 36 International Units (IU) for this preparation. 
The active “substance” is somatropin (recombinant human growth hormone).

What Genotropin Is

Genotropin is the brand name for somatropin, a recombinant human Growth Hormone (HGH) manufactured by Pfizer. It is used medically to treat conditions such as:

• Growth hormone deficiency (children & adults)

• Turner syndrome

• Prader–Willi syndrome

• Chronic kidney disease–related growth issues

• Muscle wasting in HIV patients

It comes in pens or cartridges, and 36 IU refers to the total international units of growth hormone in the product.

 Common Side Effects

Common / Mild

• Water retention (bloating, puffiness)

• Joint and muscle pain

• Tingling or numbness in hands/feet (carpal tunnel–like symptoms)

• Increased fatigue

• Headaches

• Increased blood sugar / insulin resistance

More Serious (Medical Attention Required)

• Carpal tunnel syndrome

• Gynecomastia (breast tissue enlargement in males)

• High blood pressure

• Increased risk of diabetes long-term

• Swelling around organs or extremities

• Enlarged organs with chronic misuse

• Growth of existing cancers (HGH can stimulate cell growth)

Long-Term Abuse Risks

• Acromegaly-like symptoms (jaw, hands, feet thickening)

• Heart enlargement

• High cholesterol

• Metabolic dysfunction

Important: HGH should only be used under medical supervision. Misuse can cause irreversible damage.

Why Bodybuilders Use Genotropin 

Even though this is not medically recommended, some athletes use HGH for:

1. Fat Loss (Enhanced Lipolysis)

HGH increases the breakdown of stored fat, making the physique look “tighter.”

2. Muscle Fullness / Cell Volumization

HGH increases water inside muscle cells, giving a rounder, fuller look.

3. Increased IGF-1 Levels

HGH stimulates the liver to produce IGF-1, a hormone that supports:

• Muscle cell growth

• Recovery

• Tissue repair

4. Recovery & Injury Healing

Athletes claim faster recovery from training, tendon injuries, and soft-tissue damage.

5. Anti-Aging Appearance

Improved skin texture, reduced wrinkles, improved hair quality.

Again: these uses are off-label, not FDA approved, and carry significant risks.

What Bodybuilders Commonly “Stack” With HGH (Conceptual Explanation)

(No doses or instructions will be given.)

Bodybuilders often combine HGH with other substances because HGH works best synergistically with hormones that increase protein synthesis.

1. HGH + Testosterone

This is the most common combination because:

• Testosterone increases muscle protein synthesis

• HGH increases IGF-1

• Together they create a stronger anabolic environment

2. HGH + Insulin (High Risk)

Some advanced users combine low levels of insulin to optimize nutrient partitioning.
However, insulin stacking is extremely dangerous, can cause fatal hypoglycemia, and should never be attempted without medical supervision.

3. HGH + Anabolic Steroids (e.g., Trenbolone, Deca, Anavar)

Users combine these to maximize:

• Muscle growth

• Fat loss

• Recovery

Risks multiply significantly when stacking multiple hormones.

4. HGH + Peptides (GHRPs / GHRHs)

Some use peptide combinations (e.g., CJC-1295 + Ipamorelin) to enhance natural GH pulsation.
However, using these with HGH can disrupt endocrine feedback loops.
