Advertisements on the Internet and in spam e-mail appeal to health-conscious consumers — Look and Feel 20 Years Younger with HGH! Lose Unwanted Wrinkles! Increase Muscle Mass! Lose Weight While You Sleep! Restore Youthful Vision! Enhance Sexual Performance! HGH Now Available without a Prescription!

Do HGH supplements really work? In response to subscriber questions, we took an in-depth look into the efficacy of these products and the claims they make.

This special Review covers the science behind human growth hormone — the controversy and HGH limitations as a non-prescription supplement. We looked into four main product categories and give you our assessment:

  • HGH Releasing Agents (also called "HGH enhancers" or "HGH stimulators") — who benefits?
  • Homeopathic HGH — efficacy of extreme dilution?
  • Nanogram Strength HGH — dosage level and absorption?
  • IGF-1 Enhancers — enhancing what?
This evaluation is based on a comprehensive review of the evidence in the literature. It is not based on our usual testing of the products. However HGH supplements such as SeroVital-hghBotanic Choice HGH Booster Formula, and Renewal HGH Advanced Formula are described and compared along with a listing of their ingredients and our comments. Consumer tips and precautions also are provided.
