Extend Your Prime*

Growth Hormone (GH) is produced by the pituitary gland in your brain, and it’s tied to increased lean muscle mass, more energy, increased libido, and more.

By your 30s, the pituitary gland begins making less GH… and by age 55, your GH levels could’ve already dropped by up to 85%.​

GF-9® CORE is the perfect solution for men looking to boost their GH levels back up.*

This formula uses clinically dosed ingredients to nourish the pituitary gland. By doing so, it naturally boosts GH production to brings levels closer to what you may have experienced in your 20s and 30s.*

Best of all, GF-9® CORE starts working in as little as 90 minutes.

The Ultimate Body Hack

GH is vital for development and maintenance of the body.

Healthy GH levels are tied to:

  • More Lean Muscle
  • Lower Body Fat
  • Better Mood and Focus
  • Deeper, More Restorative Sleep
  • Fewer Visible Wrinkles

Less than the Cost of Injections

For a significant and relatively quick boost in GH levels, men should take GF-9® CORE every day.* It’s a fraction of the cost of painful injections, and it does things traditional multivitamins simply don’t do.

Directions

GF-9® CORE Directions

DIRECTIONS: Adults take 4 capsules with water on an empty stomach, either in the morning 2 hours before breakfast or 2 hours after dinner prior to bedtime.

Age Won't Slow You Down.

You think fast, act sharp, and move with purpose. But when your body can no longer keep up with your ambition, it’s time to look at what’s changed inside.

By 55, your growth hormone (GH) levels can fall up to 85%. That’s when energy can dip, muscle can soften, and drive can fade.

Screw that.

GF-9® CORE helps increase your body’s natural GH production, and it starts its work in as little as 90 minutes.*

Questions? We’ve Got You Covered.

What is growth hormone (GH)?

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.
Is GF-9® CORE putting hormones into my body?

Neither formula includes any hormones. Both formulas work WITH your body to naturally increase the production of youth hormone.*
Does this have any harmful side effects?

All the ingredients in GF-9® CORE have a history of safe use in healthy adults.
Will this formula show up on a drug test?

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.
Does GF-9® CORE have a money-back guarantee?

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.
