Peptide Insulin-like Growth Factor-1 (IGF-1): IGF-1 LR3 VS IGF-1 DES

Insulin-like Growth Factor-1 (IGF-1): IGF-1 LR3 VS IGF-1 DES


IGF-1 (insulin-like growth factor) is an endocrine hormone that is produced in the liver. The production of IGF-1 is increased in the presence of growth hormone. IGF stands for insulin-like growth factor. Insulin-like growth factor 1 (IGF-1) is a protein hormone polypeptide similar in molecular structure to insulin. It plays an important role in children's growth and continues to affect adults. It is a natural substance that is produced in the human body and is at its highest natural level during puberty. During puberty, IGF is most responsible for the natural muscle growth that occurs in those few years. There are many different things that IGF does in the human body. Among the most positive effects are increased amino acid transport to cells, increased glucose transport, increased protein synthesis, decreased protein breakdown, and increased RNA synthesis.

IGF-1 benefits:

Why is this IGF-1 important to a bodybuilder or athlete? Let's take a look at the list:

  • Helps regulate fat for use as energy, resulting in fat loss.
  • Contributes to anti-aging. As we get older, IGF-1 production slows down and this leads to cellular reduction. Low IGF-1 levels are linked to heart failure, lower brain cell regulation, and neuron function. Not to mention the breakdown of muscle tissue.
  • Helps to increase the nutrient shuttle (protein synthesis).
  • Increases the regenerative functions of the nerve tissue.
  • Increases the ability to cause hyperplasia in muscle cells, resulting in fuller muscle tissue.

Why use IGF-1?

Simply put, the gains from IGF-1 (all variants) are not due to water weight, so the gains you make are long term muscle growth. This is compared to steroids, which are known to add water to your body and cause nasty side effects. You won't gain 10 pounds from using IGF-1, but you will see solid 1 to 2 pounds gains in 1-2 weeks.

The most important factor to consider is the ability of IGF-1 to reach hyperplasia. When you use steroids, you help the body through hypertrophy, which means that you enlarge the muscle cells that are present. On the other hand, IGF-1 causes hyperplasia, which means that you are actually increasing the number of cells in muscle tissue. These new cells can be used through further exercise, and use of steroids to make muscles bigger. In essence, with IGF-1, you can achieve more muscle density and size at the genetic level.

IGF-1 variants:

IGF-1 variants are divided into two groups: IGF-1 LR3 and DES IGF-1 (usually represented as IGF-1 DES). Base IGF-1 has a very short half-life (about 10-20 minutes); as a result, it is quickly destroyed by the body. For this reason, IGF-1 was modified to produce the amino acid analog IGF-1 LR3 (Lange). The other variant of IGF-1 called DES IGF-1 is a truncated version that is 10 times more effective than IGF-1. Both variants are similar to the root but have different actions so they can work in specific ways.


Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and an elongated analogue of human insulin-like growth factor 1 (IGF-1). IGF-1 LR3 has a half-life of around 20-30 hours and is much more effective than Base IGF-1. Since its half-life is around a day, the IGF-1 LR3 circulates around the body, for around 24 hours, binding to receptors and activating cell communication, which improves muscle growth and fat loss.

LR3 prevents glucose from entering cells which, in turn, forces the body to burn fat, not sucrose. In addition, its long half-life is desirable for another reason; On-site injections are not required as IGF-1 LR3 cycles through attachment to all muscle cells for about a day.

Long R3 IGF-1 is significantly more effective than IGF-1. The increased effectiveness is due to the reduced binding of Long R3 IGF-1 to all known IGF binding proteins. These binding proteins normally inhibit the biological effects of IGFs.



DES IGF-1 is the shorter version of the IGF-1 chain. It is five (5) times stronger than IGF-LR3 and ten (10) times stronger than regular base IGF-1. The half-life for DES is around 20-30 minutes, which means that this is a very delicate chain. Therefore, it should be administered only to the point where you want to see muscle growth. DES has the ability to stimulate muscle hyperplasia better than LR3. In simple terms, it is best used for spot injections, rather than overall growth.

of (1-3) IGF-1 is missing the first three amino acids at the N-terminus of IGF-1 (for a total of 67 amino acids, relative to 70 of IGF-1). As a result of this difference, it has significantly reduced binding to the insulin-like growth factor binding proteins (IGFBPs) and increased potency compared to IGF-1.


In addition, DES is known to bind to receptors that have been deformed by lactic acid, which is often present during exercise. This allows the DES to bind to a mutated receptor and signal tissue growth during exercise. DES can be used longer and more often than LR3.

IGF-1 cycle, Dosage and injections:

The most effective length for a cycle of IGF is 50 days on and 20-40 days off. The most controversial controversy surrounding Long R3 IGF-1 is the effective dosage.

The most common dosages used are between 20 mcg / day and 120 + mcg / day. IGF is only available in milligrams, one mg gives you a 50 day cycle at 20mcg / day, 2mg gives you a 50 day cycle at 40mcg / day, 3mg gives you a 50 day cycle at 60mcg / day, 4mg gives you a 50 day cycle at 80mcg / Day and so on.


IGF-1 LR3 can be taken 7 days a week at a dose of 50-150 mcg per day. Desensitization has been shown to occur in about 40 days or about 4 weeks. Injection sites can be on any muscle group in the body as it is not very good at site-specific growth.


DES IGF-1 can be dosed several times a day with 50-150 mcg (before training) in certain target areas. since DES has such a short half-life (20-30 minutes), desensitization was not noticed at all. Injection sites should be located; preferably, the muscle group you want to grow. In simple terms, if you want to grow your biceps, inject IGF-1 DES directly into your biceps.

IGF-1 Side effects:

It should be noted that high doses of IGF-1 are known to cause hypoglycemia, but nowhere near near insulin levels. It is also pointed out, and much discussed, that IGF-1 has been shown to increase tumor size in cancer patients. While this fact may be true in patients with pre-existing cancer, IGF-1 is not the cause of cancer; In fact, our bodies need IGF-1 in order to regulate heart function, stimulate the nervous system and brain cells. People with low IGF-1 levels have been found to have low protein counts and muscle mass, which, in turn, can be just as unhealthy. If you have a headache, don't take a whole bottle of aspirin. Likewise, to protect yourself from ignorant mistakes, IGF-1 should be administered properly and never misused.

IGF-1 LR3 pictures

Long Arg3 insulin-like growth factor-I (Long-R3-IGF-I) is an 83 amino acid analog of IGF-I, comprising the complete IGF-I sequence with the substitution of an Arg for the Glu at position 3 (hence R3) , and a 13 amino acid extension peptide at the N-terminus. Long-R3-IGF-I is significantly more effective than IGF-I in vitro. The increased effectiveness is due to the significantly reduced binding of Long-R3-IGF-I to IGF-binding proteins, which normally inhibit the biological effects of IGFs.

Quick start Guide:
1. Dab the top of your sterile vial with an alcohol prep pad (70% isopropyl alcohol)
2. Mix 7.5 ml of distilled water with 1.0 ml of vinegar
3. Add Whatman syringe filter
4. Add sterile ~ 20ga. Needle to the end of the Whatman filter
5. Inject the 8.5 ml solution into the sterile vial
6. You now have a sterile 0.6% acetic acid

Reconstitution of IGF-1 LR3:

Reconstitution is simply the addition of the 0.6% AA to your lyophilized IGF-1.
Assumption: 1mg / ml IGF-1 / AA (1mg IGF-1 is combined with 1 ml AA; 1mg IGF-1 corresponds to 1,000 mcg)

1. Dab the top of your IGF-1 vial with a sterile alcohol prep pad
2. Dab the top of your 0.6% AA vial with a sterile alcohol prep pad
3. Use either multiple insulin syringe volumes (example: 2 x 0.5 cc) or a single large syringe to obtain 1.0 ml 0.6% AA.
4. In the IGF-1 vial, put a sterile ~ 20 ga. Needle as a vent
5. Inject the 1.0 ml AA very slowly and trickle down the side of the vial.
a. Be very careful with this peptide as it is very sensitive!
6. Remove the needle & syringe and throw away
7. Gently rock the vial or roll it between your hands.
a. Again, be very gentle here
8. You now have 1 mg / ml IGF-1
a. This is the same as: 1,000mcg / ml
