Gonadotropin (HCG) is used to stimulate testicles to restore testosterone and sperm production during or after a steroid cycle which has caused natural levels to be reduced. Also, using HCG with TRT or during steroid cycle can restore your testicles to their normal, healthy size and function. 

• Used after a cycle, to help restore testosterone production more quickly (in combo with Nolvadex or Clomid)
• On cycle, in an effort to avoid testicular atrophy during steroid administration.
• Usage: 2000-3000 Units every 2nd or 3rd day, taken for no longer than 2 or 3 weeks.
