HMG vs Testosterone
Extensively Studied vs FDA Approved
monitor Mechanism-based · 60% Both HMG and Testosterone can elevate estrogen. Combined estrogenic load increases risk of gynecomastia, water retention, and mood changes. Monitor estradiol levels and consider AI if needed.
Molecular Data

Key Benefits
HMG
01 FDA-approved for fertility treatment
02 Stimulates ovarian follicle development
03 Contains both FSH and LH naturally
04 Promotes spermatogenesis in men
05 Cost-effective alternative to recombinant FSH
06 LH activity may improve fertilization rates
07 Long clinical track record
08 Lower OHSS incidence with HP-hMG
Testosterone
01 Restoration of normal testosterone levels in hypogonadal men
02 Increased lean muscle mass and strength
03 Improved bone mineral density and reduced fracture risk
04 Enhanced libido, sexual function, and erectile quality
05 Improved mood, energy, motivation, and cognitive clarity
06 Reduction in body fat percentage, particularly visceral fat
07 Increased red blood cell production and oxygen-carrying capacity
08 Improved insulin sensitivity and metabolic health markers
