What are the most common mistakes with HCG (Human Chorionic Gonadotropin)?
The most common HCG (Human Chorionic Gonadotropin) mistakes are running it solo as a 'natural' alternative to TRT, ignores estrogen and long term axis effects; skipping estrogen monitoring during PCT pulses; mixing pharmacy-grade HCG with research grade product without understanding the IU-vs-mg labeling difference. Most issues people run into come down to protocol and expectations, not the compound itself. Going in informed matters here because human evidence for HCG (Human Chorionic Gonadotropin) is limited.
Common HCG (Human Chorionic Gonadotropin) mistakes
- Running it solo as a 'natural' alternative to TRT, ignores estrogen and long term axis effects
- Skipping estrogen monitoring during PCT pulses
- Mixing pharmacy-grade HCG with research grade product without understanding the IU-vs-mg labeling difference
- Confusing HCG with HMG (different gonadotropin, different role)
Bloodwork worth tracking
- Total + free testosterone
- Estradiol (sensitive assay)
- LH / FSH (PCT context)
- PSA if older
