IGF1 LR3 Peptide Review: Benefits, Before & After, Dose, & More

Peptides are chains of amino acids. Our body produces these small chains of amino acids linked with peptide bonds.

However, many people also use peptide solutions such as IGF1 LR3 for enhanced performance, collagen production, muscle growth, and other benefits.

It is important to learn about these growth hormones before using them to make a well-informed decision.

IGF1 LR3 is one of the most popular peptides available on the market. It has an insulin-like growth factor (IGF1-1) that surfaced in the 1990s.

Renowned Dorian Yates allegedly used the drug during the competition to help him gain mass and become humongous.

In the earlier days, these drugs were only available to professional athletes, but now they are available to the general public.

The IGF1 LR3 is a synthetic peptide that is a lengthened version of the IGF1 peptide hormone.

IGF1 has a smaller chain with 70 amino acids, and the IGF1 LR3 has 83 amino acids.

The IGF1 LR3 is the agonist of IGF1 and has improved metabolic stability. This, in turn, results in higher potency.

You can expect it to be 3 times more potent than the IGF1. Moreover, it also has a longer half-life of 20 hours.

There are several uses and benefits of the IGF1 LR3, including the boost in metabolic rate, burning fat reserves, and increase in muscle building capacity.

If you are interested in many of its uses, then you need to learn how it works.

Here is a list of many benefits:

  • Regeneration of the whole body
  • Increased cellular repair
  • Anti-aging properties
  • Increased collagen production
  • Muscle growth
  • Induces muscle hyperplasia
  • The growth of new muscle cells
  • Increased bone mineral density
  • Improved learning and memory
  • Regeneration of the nervous system and brain health
  • May reduce the risk of cardiovascular diseases
  • Boost immune system
  • Anti-inflammatory
  • Improves gut health

How Does IGF1 LR3 Work?

For its different uses, the IGF1 LR3 works by binding to the cell receptors in the muscle cells that activate cell communication.

This, in turn, improves the growth of different muscles throughout the day.

It is a major hormonal mediator of natural growth and helps with the stimulation of IGF-1 secretion, usually in the liver and other tissues.

These secretions are homologous to insulin receptors, and the synthesis of IGF1 helps with the start of different processes that all lead up to stature growth.

It also restrains the movement of glucose to enter the body cells; this, in turn, helps with the burning of fat.

Your body then starts using the fat for the production of energy, which helps in fat loss.

Other than that, the IGF1 LR3 is great for building muscles as it is capable of stimulating proliferation and the differentiation of muscle stem cells, promoting the real growth of new muscles.

The IGF1 LR3 hormone regulates the process of DNA synthesis and helps with the cells in different parts of the body.

These parts of the body are different from the muscles like the cartilage, organs, hematopoietic cells, and bone.

IGF1 LR3 Before and After Results

We scoured the internet to find credible reports of before and after results from people using IGF1 LR3, and came across seemingly credible reports.

Here’s a few of them:

My pec had a knot and bruising where the tear was. That was gone in 3 days. This is magical. That’s the experience I have with it, I’ll keep updating this as it goes along. -NotAnotherGearAccoun (Reddit)

I pinned both BPC 250ug x 2 and LR3 100ug for the first time yesterday to address a bad rotator cuff and knee on the right and hip/psoas on the left. Had I known I would wake up with each a SOLID 60% better the very next day I would have used them separately. I’m absolutely stunned. I’ve been in pain every day for 8 months and have tried it all. I felt so free today…played basketball for 90 minutes, then volume bench presses and first pushups in about 6 months. -L99ATL (Reddit)

Periodically I run 100mcg a day for 4 weeks. As an additive, enhances my cycle. I would recommend. Does not have the fat reduction of hgh. Increases LH and FSH. I notice balls get bigger and load increases a lot. -BearParts (Reddit)

Side Effects of IGF1 LR3

When you consider getting a muscle-building supplement, you may think of all the possible side effects you may have to face.

Before you make the decision to start these growth hormones, you must learn of all the possible side effects and how likely you are to face them:

Possible side effects emerge when you start taking the 100mcg range daily.

If you were to stay on the cycle for 30 or more days, then you can expect side effects such as headaches, hypoglycemia, and nausea.

These side effects are mild. However, if you were to increase the dosage, you might have to face severe side effects such as bubble gut.

This is where there is growth in the different organs of the digestive system.

Other than that, you may also face irregularities in your blood sugar.

Lastly, you may also experience acromegaly in the jawline and the hands and elbows.

There are no researches that support the claim that IGF1 LR3 can grow organs in your gut.

But this is a common problem with different peptides.

Organ growth is not something to take likely; it is irreversible, which is why it is best to keep your dosage at a minimal and shorter cycle to avoid facing any side effects.

The below video also touches on a few of the side effects mentioned above:

Does IGF1 LR3 Really Work?

Different companies may claim that these supplements work, but it is important to learn from the experiences of people who have actually used and benefited from them.

There is a lot of speculation about how the IGF1 LR3 works.

However, in this case, it is just because of less scientific data.

There have been clinical trials that suggest that the IGF1 LR3 has a high affinity with the IGF1 and is more metabolically stable.

And that it has the capability to stimulate the growth of new muscle stem cells.

Other than that, users have experienced different changes in their energy and libido levels.

Other users have also claimed that the supplement has improved the quality of their sleep, and that it has enhanced the regenerative effect of their sleep.

There have been instances where doctors have prescribed this peptide for both children and adults to help them with their developmental issues.

There is no simple answer. For some people, the supplement has done wonders.

How To Use IGF1 LR3?

Since the IGF1 LR3 is a potent peptide, it is important to use the right dosage as you might see effects from the slightest of doses.

This compound does not take time to load into your body, so you can start seeing results almost immediately.

It is suggested that users stick to minimal doses and smaller cycles.

The optimal dosage for men is between 40 and 50 mcg of IGF1 LR3, while for women, the dosage should remain within the 20 mcg bracket.

If you exceed the limits, you may experience high side effects.

This drug has a half-life of 20-30 hours which means that you shouldn’t use this drug more than once a day.

Taking it more than once may disrupt the cycle.

Going for longer cycles may result in bad side effects.

You can complete a 4-week cycle, but it is also important for you to take at least 8 months off of the drug to avoid any side effects.

After the break, you can start another cycle. 4-6 weeks are the best for each cycle.
