IGF1 LR3, also known as Insulin-Like Growth Factor-1 Long r3, is among the most popular peptides available. It generates new muscle cells and thereby affects muscle growth enormously. But what else can IGF1 LR3 do? We clarify:

IGF1 itself arises when testosterone, HGH (growth hormone) and insulin meet in the liver. IGF1 does not just provide muscle growth, but the formation of completely new muscle cells. This results in the new formation of completely new muscle mass.

IGF1 LR3, insulin-like growth factor-1 Long R3, is a polypeptide that is actually used as a peptide for research purposes in the area of ​​muscle growth. It also acts as a glucose booster, which means that glycogen stores are filled much faster.


IGF1 LR3 has many properties of the growth hormone HGH. Studies have even shown that IGF1 LR3 not only favors the regeneration of muscle cells as in HGH, but also the division of new and existing cells, which is also called hyperplasia, and in turn causes the divided cells to grow and form new muscle mass. As a result, the muscle density is radically increased, which is also seen in some of the top Bosüdybuilders, as these are lighter in comparison to some other, but 15Kg look heavier due to the plumpness.

IGF1 LR3 has basically the same structure as insulin. It belongs to the subcutaneously as well as intramuscularly injected peptides. Due to the described effect, IGF1 LR3 can be described as extremely anabolic.

IGF1 LR3 favors nitrogen storage and protein synthesis. This causes next to the new formation of muscle cells and muscle growth. In addition, this peptide has a very fat-burning effect and is therefore considered to be a functional active ingredient in neurological functions, such as brain function and associated cognitive abilities.

The effect of IGF1 LR3 at a glance:

Reconstruction of muscle cells
-Faster regeneration
– Improved sleep quality
-Strengthened protein synthesis
– shortening of training breaks
– Improved brain function

Difference LR3 to IGF1:

Compared to conventional IGF, LR3 is virtually bound to an Esther which ensures that the active substance not only remains stable and effective for a few seconds, but expands its effect up to 20 hours hours. You can almost compare this to testosterone propionate and enantate as far as the difference is concerned. However, IGF1 LR3 is 2-3 times more potent and potent in its action due to the longer-lasting effect of cell regeneration compared to normal IGF1.


The most common dosage for IGF1 LR3 are applied 1-2 100mcg different:
– Subcutaneously 100mcg in the morning and after training on training days
-Subkutan 100mcg in the morning and before sleeping on non-workout days
-Intramuscular 100mcg divided, for example, chest was trained, then 50mcg are injected in the left and 50mcg in the right breast. This leads to the acceleration of local muscle growth, faster regeneration and should be a very effective method.


-Can be used as an only peptide
Considered to be relevant is the injection of testosterone for a stable effect
It is often combined to form HGH, since the modes of action of the substances can mutually increase each other
is often combined with PEG MGF as this peptide enhances the action of IGF1 LR3 and also causes local muscle growth.

Side effects:

As with all peptides is also here to say that nothing precise about the side effects can be said and the enumerated things are gained from experience.
– Temporary water retention subcutaneous
– Headache
– Joint pain
– Hunger attacks
– Aching
