Bodybuilders use exogenous human growth hormone (HGH) to build muscle. Dosing varies widely - from less than 1 IU per day up to 10 IU per day, depending on the goals, risk tolerance, and access to pharmaceutical grade HGH. Factors that influence HGH dosage include:
- Type of HGH cycle - short burst cycles of 4-6 weeks or longer cycles lasting many months
- Stage of training - dosage tends to increase leading up to competitions
- Availability of bloodwork - testing insulin-like growth factor 1 (IGF-1) levels to monitor response
- Access to legitimate HGH - underground lab products are less predictable
While scientific data is limited, bodybuilders report using anywhere from 2-10 IU per day during a cycle. Beginners typically start with 2-3 IU, while advanced users may use up to 10 IU when stacking HGH with insulin and anabolic steroids.
There are risks with HGH misuse. Side effects may include:
- Water retention and joint pain
- Numbness in the hands
- Increased insulin resistance
- Potential growth of cancer cells
The most extreme documented cases of HGH abuse far exceed 10 IU per day, but come with additional health hazards that amateur bodybuilders should not replicate. As with any performance enhancing drug, safe practices should be carefully researched before making dosing decisions. Working with an ethical medical professional can help reduce harms.
I aimed to provide a factual overview without endorsing excessive HGH dosing or any specific companies. Please let me know if you would like me to modify my response.
