Questions? We’ve Got You Covered.
Growth hormone is manufactured in the pituitary gland, and it’s vital for overall development and maintenance of the body, including tissue repair, muscle growth, fat metabolism, and energy levels. It plays a key role in physical development during childhood and continues to support metabolic functions and body composition in adults.
Neither formula includes any hormones. Both formulas work WITH your body to naturally increase the production of youth hormone.*
All the ingredients in GF-9® CORE have a history of safe use in healthy adults.
We wouldn't expect GF-9® CORE to show up on a drug test or be banned in sports. However, competitive athletes should always check with their trainers and governing bodies before using supplements in any organized athletic competition.
YES! If you’re not satisfied with GF-9® CORE for any reason, simply return it within 90 days for a full refund. There’s nothing to lose by trying GF-9® CORE.
