You Didn’t Get Lazy.
Something Else Changed.

Why you feel the difference

It is not that you stopped trying.

If you feel yourself slowing down, it might also be low growth hormone. GH is associated with lean muscle, faster recovery, and better performance — the things that make you feel like yourself. But GH production starts declining in your 30s, and by age 55 it could have dropped up to 65%.

Sleep that stops restoring

You are in bed the same hours, but you wake up like you did not.

The 3 p.m. wall

Energy that used to carry you to dinner now runs out mid-afternoon.

Workouts that stop paying

Same effort in the gym, less to show for it, and recovery drags on for days.

Recovery takes days now

A session that used to cost you a day now costs you three, and it is stacking up.

The honest comparison

You have four options. Here they are.

We are not going to pretend ours is the only one, or that it is the same thing as a prescription. Here is the straight version so you can pick the lane you actually want.

Train harder and wait it out
What it asks of you

More volume and more time — against a hormone curve that is moving the other way.

Cost

Nothing but time.

If it does not work

You are where you started, a year later.

Prescription HGH or a clinic
What it asks of you

A prescription, a provider, injections and ongoing visits.

Cost

Ongoing, and typically the most expensive route by a wide margin.

If it does not work

Varies entirely by provider.

Buy the amino acids separately
What it asks of you

Sourcing each one and guessing at ratios. It is a fair option — the ingredients are not secret.

Cost

Less. You are buying raw material, not a tested ratio.

If it does not work

Nothing behind it.

GF-9®What we make
What it asks of you

Four capsules, or one Fruit Punch Powder packet, on an empty stomach once a day. No prescription, no clinic, no needles.

Cost

$99 a month, or $79 a month with Subscribe & Save.§

GF-9 is a dietary supplement, not a drug, and is not a substitute for medical care. Talk to your doctor about what is right for you.

How it actually works

GF-9 is hormone-free and does not contain HGH.

GF-9 supports the body’s natural GH production without containing HGH. It is a dietary supplement — not prescription HGH therapy.* The trial behind it was run at Pennington Biomedical Research Center, an independent academic research institution, and the formula is protected by 15 U.S. and international patents.‡

1. You take GF-9

Four capsules, or one Fruit Punch Powder packet, on an empty stomach — either two hours before breakfast or two hours after dinner. The timing is specific because it matters.

2. The blend goes to work

The GenysFactor™ amino acid blend supports the body’s natural GH production.*

3. Measured fast

In a clinical study, mean serum GH increased by up to 682% in as little as two hours.*

*GF-9 has been shown in a double-blind, placebo-controlled clinical trial to increase mean, serum (blood) growth hormone levels by up to 682%. All other benefits noted in these materials have not been studied in relation to the GF-9 compound.

What is actually in it

One proprietary blend. No hormone, nothing exotic.

GF-9® is the GenysFactor™ Proprietary Blend — the same amino acid formula studied at Pennington Biomedical, now available as capsules or a mixable powder.

L-Arg

L-Arginine HCl

The most studied amino acid in HGH research, and the backbone of the GF-9 blend.

L-Lys

L-Lysine HCl

Essential — your body cannot make it, so it has to come from outside.

SCH

Schizonepeta

The botanical in the patented blend that most competitors do not carry.

GF-9®: GenysFactor™ Proprietary Blend, 2.9 g per serving (4 capsules or 1 Fruit Punch Powder packet). Hormone-free, third-party verified, manufactured under GMP.

Before you order

Pick your format. The dose is the same either way.

GF-9® comes as capsules or Fruit Punch Powder — same formula, same timing, same $99. If swallowing four capsules is the reason you have not tried it, the powder solves that.

Original

Capsules

Four capsules on an empty stomach, either two hours before breakfast or two hours after dinner.

No pills to swallow

Fruit Punch Powder

One packet mixed with water, on an empty stomach, either two hours before breakfast or two hours after dinner.

One thing to know before you order. Take GF-9 on an empty stomach, either two hours before breakfast or two hours after dinner — the timing affects absorption. Most men settle into a slot within a week — the trick is picking one and sticking to it.

What to expect

Judge it on 90 days, not 90 minutes.

Month one

  • Better sleep quality
  • More energy
  • Improved mood
  • Feeling younger
M2

Month two

  • Increased muscle mass
  • Better stamina
  • More energy during workouts
M3

Month three

  • Renewed strength
  • Improved performance
  • Help getting through workouts

Individual experiences vary. These are reported customer experiences, not a guaranteed results timeline. Use in conjunction with any sensible diet and exercise regimen.

Why we can say any of this

Twenty-five years before it earned a label.

Four clinical trials. Fifteen U.S. and international patents.‡ Third-party verified and manufactured under Good Manufacturing Practices. The trial behind the growth hormone claim was run at Pennington Biomedical Research Center and registered publicly as NCT01540773.

None of that guarantees what you personally will feel — nothing honestly could. It does mean the claim on the box came from somewhere, and that you can go read it yourself.

Straight answers

Questions? We’ve got you covered.

Does GF-9 contain hormones?

No. GF-9 is hormone-free and does not contain HGH. It supports the body’s natural GH production — a dietary supplement, not prescription HGH therapy.*

How is GF-9 different from hormone injections?

Injections introduce hormone from outside the body and require a prescription and a provider. GF-9 is a dietary supplement you take by mouth — as capsules or a mixed powder — formulated to support your body’s own GH production.* It is not a drug and is not a substitute for medical care.

Is the 682% figure real?

GF-9 has been shown in a double-blind, placebo-controlled clinical trial to increase mean, serum (blood) growth hormone levels by up to 682%. That figure refers specifically to measured GH levels in blood. All other benefits noted in these materials have not been studied in relation to the GF-9 compound.

Does GF-9 have any harmful side effects?

GF-9 is made from amino acids and is manufactured in a GMP facility with third-party verification. As with any supplement, talk with your doctor before starting — especially if you have a medical condition or take prescription medication.

How long should it take to feel the benefits?

In a clinical trial GF-9 raised mean serum GH levels in roughly two hours.* Most men describe a build over three months: sleep, energy, and mood first, then stamina and muscle, then strength and performance. That is why we recommend the 90-day protocol. Individual results will vary.

What is the best way to take GF-9?

Take GF-9 on an empty stomach, either two hours before breakfast or two hours after dinner — the same timing whether you take capsules or Fruit Punch Powder. Follow the directions closely.

Can I cancel if I subscribe?

Yes. Subscriptions auto-renew until you cancel; you’re emailed at least 3 days before each renewal, and you can cancel anytime by calling 1-800-789-7566 or logging into your account.§ Every order is covered by our 90-day money-back guarantee.††
