The Science Behind IGF-1 and Muscle Growth
What is IGF-1?
IGF-1 (Insulin-like Growth Factor 1) is a hormone that helps your body build muscle. It’s produced in the liver and released into the bloodstream, where it helps your muscles grow and repair after workouts. When your body has higher IGF-1 levels, it’s able to repair muscle tissue faster, which leads to bigger and stronger muscles.
How IGF-1 Helps Build Muscle
- Muscle Repair: IGF-1 helps repair muscles after they get broken down during exercise, making them stronger and bigger.
- Protein Production: IGF-1 encourages your muscles to make proteins, which is the building block of muscle tissue.
- More Muscle Growth: IGF-1 activates pathways in the body that lead to even more muscle growth.
How SARMs Can Boost IGF-1 Production
Some SARMs can increase the amount of IGF-1 in your body by stimulating the production of growth hormone (GH), which then triggers IGF-1 production. By stacking certain SARMs together, you can boost IGF-1 even more, helping you build muscle faster. If you’re looking for SARMs stacks with peptides to maximize results, you can explore the options in our other guides.
Direct Effects on IGF-1
Certain SARMs, like Ostarine (MK-2866), can directly stimulate the liver to produce more IGF-1. This means you can get more IGF-1 in your bloodstream, which helps you build muscle faster.
Indirect Effects via Growth Hormone
Other SARMs, like RAD-140 (Testolone), can increase growth hormone (GH) levels, which leads to higher IGF-1 production. This is why stacking SARMs can help increase IGF-1 even more than using just one on its own. For more information on how stacking with HGH can further enhance results, check out our detailed guide.
Increased Sensitivity to IGF-1
Some SARMs not only increase the amount of IGF-1 in the body but also make your muscles more sensitive to it. This means your muscles can use IGF-1 more effectively, leading to even more muscle growth.
What Are SARMs?
The Basics of SARMs
SARMs are synthetic compounds designed to mimic the effects of testosterone. They work by binding to androgen receptors in muscles and bones, promoting growth and fat loss without affecting other organs. This makes them different from steroids, which can have more severe side effects like acne, hair loss, and liver damage. You can learn more about the potential side effects of SARMs on our dedicated page.
SARMs vs. Steroids
| Feature | SARMs | Steroids |
|---|---|---|
| Side Effects | Fewer, milder | Many, including severe |
| Muscle Growth | Effective, but moderate | Powerful, fast results |
| Liver Damage | Lower risk | High risk of liver damage |
| Legality | Legal in many places (except in sports) | Illegal in many places |
Types of SARMs and Their Effects
- Ostarine (MK-2866): Great for building lean muscle and improving joint health.
- Ligandrol (LGD-4033): Helps you gain muscle mass and increase strength.
- RAD-140 (Testolone): Very powerful for building muscle size and strength.
- Andarine (S4): Useful for burning fat and increasing muscle definition.
How SARMs Help Increase IGF-1 Production
Direct Effects on IGF-1
Certain SARMs, like Ostarine (MK-2866), can directly stimulate the liver to produce more IGF-1. This means you can get more IGF-1 in your bloodstream, which helps you build muscle faster.

Some SARMs not only increase the amount of IGF-1 in the body but also make your muscles more sensitive to it. This means your muscles can use IGF-1 more effectively, leading to even more muscle growth.
Best SARM Stacks for Maximizing IGF-1 and Hypertrophy
What Is a SARM Stack?
A SARM stack is when you combine two or more SARMs together to get the most out of their effects. By stacking SARMs, you can target different aspects of muscle growth and fat loss, leading to better overall results.
Ostarine (MK-2866) + Ligandrol (LGD-4033)
This is a popular stack for building lean muscle and improving strength. Ostarine helps preserve muscle while Ligandrol promotes more muscle growth and power.
- Ostarine: 10-20 mg daily
- Ligandrol: 5-10 mg daily
Cycle Length: 8-12 weeks
MK-677 + SARMs Stack
MK-677 is a growth hormone booster that can help increase IGF-1 levels. Stacking it with other SARMs like Ostarine or Ligandrol can help you build muscle even faster. You can find additional information on SARMs with testosterone boosters in our guide.
- MK-677: 10-25 mg daily
Cycle Length: 8-12 weeks
Timing and Dosage for Maximum Effect
Best Dosages for Popular SARMs
| SARM | Recommended Dosage | Cycle Length |
|---|---|---|
| Ostarine | 10-25 mg/day | 8-12 weeks |
| Ligandrol | 5-10 mg/day | 8-12 weeks |
| RAD-140 | 10-20 mg/day | 8-12 weeks |
| Andarine (S4) | 25-50 mg/day | 8-10 weeks |
| MK-677 | 10-25 mg/day | 8-12 weeks |
When to Take SARMs
- Before Workouts: Some SARMs, like RAD-140, work best when taken 30-45 minutes before a workout to boost strength and focus.
- After Workouts: Ostarine is good to take after workouts for muscle recovery and growth.
Diet and Nutrition for Maximizing IGF-1 and Hypertrophy
Important Foods for Muscle Growth
- Protein: Aim for about 1.2-2 grams of protein per kilogram of body weight to help your muscles grow.
- Healthy Fats: Foods like salmon and avocados help produce hormones, including IGF-1.
- Carbs: Eating carbohydrates after your workout helps restore energy and aids in muscle recovery.
Supplements to Support IGF-1
- Creatine: A great supplement for increasing strength and muscle size. For more information on combining SARMs with creatine, check out our page on SARMs with Creatine.
- BCAAs: These are amino acids that help with muscle repair and reduce soreness.
- L-Carnitine: Helps burn fat while protecting lean muscle mass.
Training Tips for Maximizing Results with SARMs
Progressive Overload
The best way to grow muscle is by using progressive overload. This means gradually increasing the weights or reps in your workouts to keep challenging your muscles.
Training for Hypertrophy
To maximize muscle growth, aim to lift weights in the 6-12 rep range for each exercise. Focus on compound movements like squats, deadlifts, and bench presses for the best results.
Safety and Side Effects of SARMs
Common Side Effects of SARMs
- Testosterone Suppression: Some SARMs, like RAD-140, can reduce natural testosterone production.
- Liver Health: Although SARMs are generally less harsh on the liver than steroids, it’s still important to monitor liver health during cycles.
How to Manage Side Effects
- Use cycle support supplements to protect your liver and keep your hormones balanced.
- Always follow proper dosages and cycle lengths to avoid side effects.
