@salvatorecorvus.8 and @einherjar.38 we have discussed IGF1 and suggested we make a new thread, so here it is. What are the different strategies to bypass IGF binding proteins?
IGF-1, IGF binding proteins and how to run it

I want to clarify what was discussed in the previous episodes...
Todd Lee in his video is most likely referring to IGFBPs (Insulin-like Growth Factor Binding Proteins) — these are proteins that bind to IGF1 and regulate its activity in the body. Exogenous IGF1, taken externally (for example, through injections), may not have the same effect as growth hormone (GH), because growth hormone stimulates the production of endogenous IGF1 in the body, and this process depends on various factors, including the level of IGFBPs.
When you introduce exogenous IGF1, it may be metabolized more quickly or limited in its activity because it’s not transported or activated in the body as effectively as endogenous IGF1, which is produced in response to growth hormone. Exogenous IGF1 can also bind to IGFBPs, but if the level of these proteins in the body is insufficient or imbalanced, it can limit the effectiveness of IGF1.
Thus, Todd Lee suggests that IGFBPs are important for the proper transport and activation of IGF1, and it may be necessary to take into account their levels and role to achieve the same effect as high doses of growth hormone, which also stimulates the production of IGF1 through these proteins.
As for bypassing this issue, it could include:

- Using high doses of growth hormone, which stimulates the natural production of IGF1.
- Using supplements or drugs that may regulate or increase the level of IGFBPs to improve the transport and effectiveness of IGF1.
You mentioned that you want to use the IGF-1 LR3 version. And apparently, this changes the game a bit. Here’s what our friend GPT chat says about it:
IGF-1 LR3 is a modified form of IGF-1 that has increased activity compared to regular IGF-1. Unlike standard IGF-1, IGF-1 LR3 has an extended amino acid sequence, which makes it more resistant to metabolism and increases its half-life in the body. This allows it to remain active for a longer period, theoretically giving it an advantage in stimulating cell growth and increasing muscle mass.

This allows it to remain active for a longer period, theoretically giving it an advantage in stimulating cell growth and increasing muscle mass.
How this works theoretically with IGF-1 LR3:
- Increased activity: Due to the structural change, IGF-1 LR3 can activate androgen receptors with greater intensity, which can be beneficial for muscle growth stimulation. This allows it to have a greater effect than regular IGF-1, even at lower doses.
- Less dependence on IGFBP: IGF-1 LR3 has greater resistance to binding with IGFBP (Insulin-like Growth Factor Binding Proteins), which can limit the activity of regular IGF-1. As a result, IGF-1 LR3 may have a higher degree of availability in the body since its binding with IGFBP is minimized.
- Effectiveness without the need for high doses of growth hormone: Since IGF-1 LR3 is more active on its own and has increased stability, it can work effectively even without the need for high doses of growth hormone. This bypasses the issue faced by users of regular exogenous IGF-1, where raising the IGFBP levels is required for optimal functioning.

Yeah, I think Todd Lee has a point here, because the anecdotal data we have on IGF1 is so mixed. I'm running 3ius of GH per day until November (check my cycle log to see the progress) and I ordered 4 vials of IGF1-LR3 and 4 vials of MGF from Driada. I will use 2 vials ov each alone and then 2 vials of each together. I have the perfect circumstances for an experiment like this and will post the results (I will probabl include bodyweight, progress pictures, bodypart measurments, strength and other metrics, if someone suggests anyting else)
