If you’re taking HGH injections to treat a growth hormone deficiency, you may be wondering how quickly you’ll experience results, and what will happen over the course of time while you’re on the HGH. 

The HGH results timeline will vary from person to person. A few different factors will impact how your body responds to human growth hormone injections, including your age, health status, and the dose of HGH you’re taking. 

While everyone responds to human growth hormone replacement therapy differently, most people can expect to enjoy the same benefits over time. 

To help you understand what you can expect, we’ve put together a timeline with expected results on a month-to-month basis. Read on to learn about the benefits of HGH. 

What Is Human Growth Hormone?

Human growth hormone is an essential hormone produced by the pituitary gland that supports various biological processes, including growth, cell metabolism and regeneration, cognitive functions, cardiac functions, and tissue repair in vital organs. The pituitary gland releases HGH into your bloodstream in pulses while you sleep. 

HGH also has an essential role in growth and development during childhood and adolescence. It stimulates the growth of bones and muscles, as well as helps regulate metabolism and body composition.

Low growth hormone levels affect everyone differently, depending on the severity of the individual’s deficiency and the symptoms they are experiencing. 

If you’re deficient in growth hormone as an adult, you may experience symptoms such as: 

  • Depression
  • Fatigue
  • Increased body fat, particularly around the abdomen 
  • Low libido 
  • High cholesterol levels
  • Memory problems or issues with mental capacity
  • Poor bone density 
  • Reduced muscle mass

Adults with a human growth hormone deficiency may benefit from HGH therapy, administered via injections daily or several times a week. 

What Are the Benefits of HGH?

If you’re deficient in human growth hormone, you may be overweight, feel fatigued all of the time, experience insomnia, brain fog, and lack of a sex drive. HGH deficiency also appears to increase the risk of developing age-related diseases, including diabetes, heart disease, and osteoporosis. 

HGH therapy can restore your body’s growth hormone levels to help you lose weight, increase your energy and vitality, and result in an overall protective effect for your health. While no two people will experience HGH therapy in quite the same way, there are certain benefits that you can expect to experience over the course of time. 

HGH therapy benefits include: 

  • Boosted energy levels 
  • Increased muscle mass
  • Improved mood 
  • Improved bone density 
  • Increased libido/sex drive
  • Reduced body fat 
  • Weight loss 
  • Smoother skin with even skin tone

HGH therapy can give you the boost you need to exercise regularly and live an active, full lifestyle. Those with a growth hormone deficiency may be able to use HGH therapy to gain muscle mass, lose body fat, and improve their metabolism.

Keep in mind that everyone responds to prescription HGH therapy on their own timeline. Some people will begin to see positive changes within a week, whereas others will experience the desired effects after a month or two. 

Try not to get disappointed if the benefits don’t happen as quickly as you’d like. Your body needs time to readjust and restore its levels of HGH, and this can take time. Stay patient as your body recovers from growth hormone deficiency — you will see benefits over time.  

Results After 1 Month of HGH Therapy

Most people who are on HGH therapy begin to notice subtle changes within the first month. While you may not notice any significant weight loss, you can expect to feel healthier and more energetic. Almost immediately after your first HGH injection, your HGH levels will increase and stimulate the production of IGF-1. 

After 1 month of HGH therapy, you can generally expect: 

  • Increased energy levels
  • Improved sleep
  • Less “brain fog” — improved focus and concentration 
  • More self-confidence 
  • Reduced moodiness and feelings of anxiety

Results After 2 Months of HGH Therapy

After two months of HGH therapy, cell regeneration, metabolism, and performance may improve. While you may not notice many of the changes occurring within your body, you can expect to feel much healthier. 

Collagen production can increase, which will give your skin and hair a glowing, youthful look. Bone cell production and muscle protein synthesis usually increase at this stage, helping to restore your body’s natural structure. 

After 2 months of HGH therapy, you can generally expect: 

  • Better night vision 
  • Faster metabolism 
  • Healthier looking skin and hair — fine lines and wrinkles may begin to fade
  • Improved muscle tone
  • Improved mood
  • More energy 
  • Sex drive increase

Results After 3 Months of HGH Therapy

After three months of HGH therapy, you will begin to notice the dramatic changes that have been taking place in your body. You will look and feel much more energetic and stronger, and may experience less joint pain and muscle stiffness.

After 3 months of HGH therapy, you can generally expect:

  • Boosted immune system — you get sick less often 
  • Easier to build muscle mass with exercise 
  • Enhanced sex drive and sexual pleasure 
  • Greater motivation/improved productivity 
  • Further improvement in cognitive function — better memory and focus 
  • Improved exercise capacity (you can work out longer and harder) 
  • Stronger bones
  • (For women) less PMS and/or hormone-related mood swings

Results After 4 Months of HGH Therapy

After 4 months of HGH therapy, you may begin to see optimal results. You will likely look as fit and energetic as you feel, with significant fat loss and more lean muscle. 

After 4 months of HGH therapy, you can generally expect:

  • Better, deeper sleep 
  • Continued improvement in cognitive functioning 
  • Healthier skin and hair 
  • Increased energy and endurance
  • Improved heart health 
  • Improved stamina
  • Lower cholesterol levels
  • Significantly less joint pain
  • Stronger nails

Results After 5 Months of HGH Therapy

After 5 months of HGH therapy, most of the visible improvements and benefits have already taken place. Your body composition will continue to improve. You will also generally experience: 

  • Improved skin – fewer sunspots and age spots
  • Loss of belly fat
  • Significant weight loss

Results After 6 Months of HGH Therapy

After 6 months of HGH therapy, your heart health is usually significantly improved. Your LDL (“bad” cholesterol) levels will likely drop. 

This decreases the risk of developing heart disease and offers other health-related benefits, including: 

  • Decreased inflammatory markers
  • Enhanced capacity for moderate to vigorous-intensity exercise 
  • Improved eyesight 
  • Increased muscle mass 
  • Lower blood pressure
  • Reduced temperature sensitivity 
  • Return of your natural hair color (if you previously had gray/white hair) 

Long-Term HGH Therapy Results

HGH therapy can provide health benefits in the long term, improving your health, well-being, and quality of life. 

Many people who use HGH therapy report lesser joint pain and body stiffness, helping them engage in the activities they enjoy and exercise regularly. 

Though it may take 1-2 years to reach full bone density, HGH therapy may help support stronger and healthier bones.

HGH also helps improve body composition, reducing body fat and increasing lean muscle mass. As you continue on HGH therapy, your insulin sensitivity should be within a normal, healthy range. 

For best results on HGH therapy, be sure to implement healthy lifestyle habits that support your health and longevity. Be sure to also eat a healthy, balanced diet rich in nutrient-dense ingredients, incorporating fruits, vegetables, lean proteins, and whole grains as often as you can. Exercise regularly (approximately 5 days a week for 30 minutes each day) to improve your strength, endurance, and metabolism.
