Different hormones play a critical role in strength training and bodybuilding. The common ones are:

  • Insulin
  • Growth Hormone
  • Testosterone
  • Cortisol
  • Glucagon
  • Adrenaline

Insulin is the hormone that’s responsible for the storage of glucose in muscles. The other hormones increase glucose availability, a fundamental source of fuel.

The main hormones in the training process

All these hormones play a significant part in your body’s endocrine response. If you intend to gain muscle mass, there are various ways of stimulating hormone production without using illegal supplements.

1. Insulin

Insulin is the hormone that’s responsible for storing glucose in the muscles and liver. It is an anabolic hormone that works by moving amino acids into muscle cells for repair. Insulin impacts your body muscles positively, but it could be a burden for people with excess fat.

The type of diet and exercise influence the hormone’s production. So, it’s easier to control insulin levels with food and exercise instead of injections because it’s not recommended for muscle gain.

Training increases the body’s sensitivity to insulin, and once you’ve lost weight, the body shifts into survival mode by protecting the remaining fat. Combat this response by consuming healthy fats that insulin isn’t sensitive to, such as:

  • Nuts
  • Fish
  • Coconut oil

2. HGH

Human Growth Hormone helps develop skeletal muscle tissues, eliminating body fat and increasing body strength. Its production reduces with age, and the less growth hormone you produce, the more body fat you will have.

The body releases HGH during sleep for tissue repair. Therefore, improving the quality of your sleep will help boost the release of growth hormones. Exercise also releases growth hormone, especially workouts that target multiple joints such as squats and bench presses. Therefore, the more muscles you use, the more hormone your body will produce.

Another important tip is to shorten the workout time (approximately 30-40 minutes). The quicker and more intense the workout, the more the growth hormone your body will produce. Note that HGH in professional sports has been illegal since 1989. The only way to get the injections is to have a prescription by a doctor for growth hormone deficiency.

3. Testosterone

Testicles and the adrenal glands produce testosterone. It is classified as an anabolic steroid hormone, and it’s the most crucial hormone for mass gain. It is responsible for male physical characteristics, strength, muscle mass, and fat distribution.

People have been using supplemental testosterone for building, and it works well. However, it has potentially serious adverse effects such as:

  • Blurred vision
  • Seizures
  • Inability to speak
  • And many more

That’s why testosterone is on the International Olympic Committee’s list of banned substances.

4. Estrogen

For decades bodybuilders have been using a certain amount of estrogen to maintain their androgen cell receptors. These receptors interact with testosterone to give anabolic effects. There are two primary estrogen receptors: receptor – A and receptor – B. These receptors exist in the skeletal muscle, and they directly affect muscle growth.

When supplementing testosterone exogenously, aromatase inhibitors are used to reduce estrogen conversion. However, this is not recommended because aromatase inhibitors cause estrogen joint and muscle pain and loss of bone mineral density.

5. Adrenaline

Adrenaline has an excellent strength effect on body muscles. It acts on your muscles by allowing them to contract more. Combined with other hormones, adrenaline makes you more agile, allowing you to use more energy.

6. Cortisol

The adrenal glands produce this hormone, and it’s referred to as the “stress hormone”. It is a catabolic hormone that breaks down tissues and muscles. Besides controlling inflammation, cortisol avails glucose by breaking down muscles when your blood sugar is low. This is common in endurance sports or excess training when the circulating glucose supply is used up.

7. Glucagon

Glucagon is the mirror hormone of insulin. When you fast, glucagon starts acting in your body to replenish the low glucose supplies. It also works by breaking down muscles, thus increasing cortisol, which on the other hand, stimulates the production of glucose.

8. Cytokines

There is substantial evidence showing that cytokines play an essential role in skeletal muscle growth. However, there has to be a balance between pro-inflammatory and anti-inflammatory cytokines for the regenerative process to take place.


Anabolism is the process of using anabolic steroids and related drugs for Image and Performance Enhancing. You consume these drugs to improve physical performance, increase muscle gain and strength.


Catabolism is the opposite of anabolism. People consume corticosteroids to break down muscle mass, thus reducing the total body weight.

How to gain mass?

  1. Supplements-one way of gaining muscle mass is by consuming more calories than you burn. For people who struggle with eating, mass gain supplements are convenient for boosting your calorie intake.
  2. Trains-another way to gain muscle mass is by doing endurance training rest in between the sets to stimulate testosterone. Do complete aerobic and anaerobic exercises on different days. You can also pack on muscle mass in the shortest time possible by engaging in a deadlift workout.
  3. Diet-if you’re bodybuilding, ensure you eat enough calories. It’s recommended you consume more calories than you lose during training.

How to lose weight?

  1. Supplements-there are also various dietary supplements for weight loss that come in various forms such as tablets, capsules, liquids, and powders. The products work by reducing macronutrient absorption and appetite.
  2. Trains-there are so many exercises for weight loss, such as cardio workouts, but you should train in the evening because that’s when your cortisol levels are high.
  3. Diet- If you’re trying to lose weight, you should consider several diet recommendations. For starters, eat fewer carbs so that you can increase your HGH and fast whenever you can.

Rest-another important tip is to get adequate sleep so that you can feel well-rested during the day and your workouts. It would help if you also rested between workouts to avoid inflammation and over-working your muscles.


Are you considering trying any of the tips mentioned in this review? It’s important you first have a health check to highlight any issues. These hormones are ideal for muscle gain or weight loss as long as they are used holistically.
