HCG (human chorionic gonadotropin)Glycoprotein hormone, not a simple peptide
HMG (human menopausal gonadotropin)Mixture of glycoprotein hormones (FSH and LH activity), not a peptide
Kisspeptin-10Peptide, 10 amino acids
PT-141 (bremelanotide)Synthetic cyclic peptide, 7 amino acids
TestosteroneSteroid hormone (androgen), not a peptideSide by side
What each one is and how much research is behind it.
| Name | What it is | Evidence so far | |
|---|---|---|---|
| HCG | Glycoprotein hormone, not a simple peptide | Decades of clinical use and research | Dosage |
| HMG | Mixture of glycoprotein hormones (FSH and LH activity), not a peptide | Decades of clinical use and fertility trials | Dosage |
| Kisspeptin-10 | Peptide, 10 amino acids | Small, short human studies; little long-term data | Dosage |
| PT-141 | Synthetic cyclic peptide, 7 amino acids | Phase 3 trials in women; earlier trials in men; modest effects | Dosage |
| Testosterone | Steroid hormone (androgen), not a peptide | Extensive human research, including large trials | Dosage |
