What is Genotropin?

Genotropin is the world’s leading brand of human growth hormone (HGH), manufactured by Pfizer, one of the largest and most respected pharmaceutical companies globally. Containing somatropin—a synthetic version of human growth hormone produced using recombinant DNA technology—Genotropin is biologically identical to the growth hormone naturally produced by your pituitary gland.

The Genotropin GoQuick pen represents the pinnacle of HGH delivery convenience. Unlike traditional vial-based HGH that requires mixing with bacteriostatic water, the GoQuick pen comes pre-filled and ready to use. Simply dial your dose and inject—no preparation, no mixing, no vials. Each 12mg pen contains 36 IU of pharmaceutical-grade somatropin and provides precise dosing from 0.15mg to 12mg in convenient 0.15mg increments.

  • Active Ingredient – Somatropin (rDNA origin) – 191 amino acids

Genotropin Benefits & Effects

Ultimate Convenience

The GoQuick pen requires zero preparation—no mixing, no vials, no syringes to draw. Simply attach needle, dial dose, and inject. Perfect for travel and discreet use. Takes less than 30 seconds from start to finish.

Lean Muscle Development

Stimulates protein synthesis, nitrogen retention, and muscle cell growth. Users typically gain 5-15 lbs of lean muscle mass over 3-6 months. Enhances muscle fiber quality and density, not just size.

Accelerated Fat Loss

Promotes lipolysis (fat breakdown) and increases metabolic rate. Particularly effective at reducing stubborn visceral and abdominal fat while preserving lean tissue. Improves insulin sensitivity over time.

Enhanced Recovery

Dramatically reduces recovery time between workouts. Promotes cellular regeneration, collagen synthesis, and tissue repair. Reduces DOMS and allows for more frequent, intense training sessions.

Anti-Aging Benefits

Improves skin elasticity and reduces wrinkles. Increases bone density, strengthens immune function, enhances cognitive clarity, and restores energy levels. Supports cardiovascular health and lipid profiles.

Pfizer Quality Guarantee

Manufactured under strict FDA and EMA regulations. Each batch tested for purity, potency, and sterility. The most widely prescribed HGH brand globally with over 30 years of clinical data and safety research.

How to Use Genotropin GoQuick

1. Prepare the Pen

Remove the pen cap and check the medication. The solution should be clear and colorless. Do not use if cloudy, discolored, or contains particles. Wipe the rubber stopper with an alcohol swab.

2. Attach the Needle

Remove the protective seal from a new 29G needle. Push the needle straight onto the pen and turn clockwise until firmly attached. Remove both needle caps—keep the outer cap for safe disposal later.

3. Select Your Dose

Turn the dose selector to set your prescribed dose. Each click equals 0.15mg (0.45 IU). The dose window shows your selected amount. You can dial forward or backward to adjust. Do not exceed 12mg per injection.

4. Prime (First Use Only)

For first use, prime the pen by selecting 0.15mg and pressing the injection button fully. A drop of medication should appear at the needle tip. If not, repeat once. This ensures proper flow and accurate dosing.

5. Inject

Pinch skin and insert the needle at 90 degrees into subcutaneous tissue (abdomen, thigh, or deltoid). Press the injection button fully until it clicks and hold for 5 seconds. Withdraw needle and apply gentle pressure with gauze.

6. Dispose Safely

Carefully remove needle using the outer cap and dispose of it in a sharps container. Replace pen cap. Store pen according to instructions. Use within 28 days of first use.

Pro Tips for Best Results

  • Inject at the same time daily—bedtime is optimal for natural GH rhythm
  • Rotate injection sites to prevent lipodystrophy (fat tissue changes)
  • Take on an empty stomach or 2 hours after eating for best absorption
  • Keep a consistent dosing schedule—don’t skip days
  • Store refrigerated; can be kept at room temperature for up to 28 days after first use
  • Never share your pen with anyone
