Insulin-like growth factor-1 (IGF-1) is structurally similar to insulin. In fact, they are derived evolutionarily from the same precursor molecule, diverging at about 60 million years ago. These insulin-like factors function as metabolic signaling molecules that tell the body that basal nutritional needs have been met and there are enough resources for protein synthesis and cell proliferation.

What is IGF-1 LR3?

IGF-1 LR3 for sale at a good rate. IGF-1 LR3 is a form of IGF which has been chemically adjusted with changed amino acids. It has 83 amino acids with a substation of Arginine (R) for the Glu (E) at the third spot, hence, the name R3. These modifications enable it to avoid binding with proteins in the body, enabling it to have a longer half-life.

IGF-1 LR3 is an artificial framework of a growth factor-1 (IGF-1) that works just like insulin. All these alterations make IGF-1 LR3 refrain from the pharmacological operations of IGF-1. Hence, it becomes a human-made protein and an extended version of an insulin-like factor responsible for human growth. The outcome is enhanced stability regarding body metabolism, a longer and stronger half-life, and a tripled power compared to normal IGF-1.

How Does IGF-1 LR3 Work?

IGF-1 LR3 functions as a transitional metabolite that operates on growth hormone levels within one’s body. IGF-1 has many structural similarities to that of insulin, hence, both IGF-1 and IGF-1 LR3 are utilized in the medical field and power sports due to its ability to enhance the power pointers of bodybuilders. IGF-1 LR3 encourages endurance where one can work for long periods without getting tired. Buy IGF-1 LR3 online at a good price.

Through its structure and symbolic form, the transformed IGF-1 has almost all the features contained in its original stature. With this, it provides crucial components for muscle growth and bones within the body. The side effects on the body are quite similar to supportive and unfavorable effects are bound to happen.

What makes IGF-1 LR3 stand out from its competitors is its prolonged effects. It was initially developed to biologically upgrade the activity standards of IGF-1 by having 83 amino acids that head to its concluding exceptional results.

When IGF-1 LR3 was undergoing lab tests, it was established to contain twice the amount of energy when compared to the original version. This explains why the anabolic effects of this peptide are more prominent, with lasting effects. This results in significant muscle growth over a short period of time that doesn’t last more than six weeks.


IGF-1 LR3 and IGF-1 DES have been shown to have increased potency, causing 3 to 5 fold increases in all growth and proliferative responses in rat models. The high potency of the LR3 analog was achieved by incorporating glutamine to arginine substitution at position 3 of the peptide. Similarly, IGF-1 DES is the result of a three amino acid truncation at the N-terminus of the peptide. In both analogs, these mutations effectively lower the binding of IGF-1 to the IGF-1 binding proteins and extended the half-life of the protein.

IGF-1 LR3 Benefits and Results

IGF-1 LR3 rarely causes an allergic reaction, hence there are potentially no IGF-1 LR3 side effects. In case it does appear, it would be on very few circumstances according to different individuals. It can boost the following effects:

  • Accelerate the rate of movement of amino acids within the body.
  • Heighten the speed by which glucose is transported in the body.
  • Slow down protein degradation
  • Sustain high protein synthesis
  • Increase endurance and performance
  • Releases depression from the body
  • Increases RNA synthesis in the body
  • Hastens the rate at which fat is burned through rapid weight loss.
  • IGF-1 LR3 in bodybuilding helps sustain lean muscles.

Insulin-like Growth Factors 1 Long R3 Hair Growth

The IGF growth factor is also produced in the hair follicle which promotes hair growth by proliferating keratinocytes, hence, improving alopecia. Patients with alopecia can utilize IGF-1 as it helps in hair growth and forestation of hair growing power.

IGF-1 LR3 Dosage

IGF-1 LR3 dosage varies in different individuals due to different needs. To get the best results, IGF-1 LR3 is administered in controlled doses. On a daily basis, such doses are around 10 mcg – 50 mcg.

How Do I Reconstitute?

Mix 2ml of the water and peptide together into the syringe and inject it into the vial with powder. Never shake, but gently rotate the vial between your fingers until all of the powder has dissolved. As a general procedure, the manufacturer recommends reconstituting IGF-1 LR3 in sterile, distilled water, with light sonication if necessary.


Although it is stable at room temperature for up to 3 weeks, lyophilized IGF-1 LR3 powder should be stored below -28°C. Upon reconstitution, the IGF-1 LR3 solution should be stored at 4°C for less than 7 days and below -10°C for a longer time. buy IGF-1 Lr3 online. Repeat Freeze-thaw cycles should be avoided for IGF-1 LR3 solution.
