IGF-1 DES and IGF-1 LR3 Interaction

Monitor
Researched 90% confidence

IGF-1 DES and IGF-1 LR3 have an interaction requiring monitoring for interaction with 90% confidence. Do not stack with IGF-1 DES. Both are IGF-1 analogs acting on the same receptor. Choose one or the other based on whether you want systemic (LR3) or localized (DES) effects. Both compounds affect the pituitary, so monitoring these systems is recommended.

Compound Profiles

IGF-1 DES

Truncated IGF-1 Analog | Localized Muscle Growth

IGF-1 DES activates the IGF-1 receptor (IGF-1R) and downstream PI3K/Akt/mTOR and MAPK/ERK signaling pathways, driving both muscle hypertrophy and hyperplasia. Because it lacks the tripeptide Gly-Pro-Glu at the N-terminus, it cannot bind to IGFBPs that normally sequester ~98% of circulating IGF-1.

IGF-1 LR3

Modified Growth Factor Analog | Muscle Growth

Functions as a full IGF-1 receptor agonist activating PI3K/Akt/mTOR and MAPK/ERK pathways. The modifications prevent protein sequestration, maintaining elevated free circulating levels for extended anabolic effects.

Half-life: 20-30 hours Typical dose: 20-100 mcg daily (start low at 20-30 mcg) growth hormone, healing

2x 2 compounds affect insulin sensitivity (IGF-1 DES, IGF-1 LR3). Monitor fasting glucose and HbA1c.

Frequently Asked Questions

Can I take IGF-1 DES with IGF-1 LR3?

Yes, but with caution. Do not stack with IGF-1 DES. Both are IGF-1 analogs acting on the same receptor. Choose one or the other based on whether you want systemic (LR3) or localized (DES) effects. Regular monitoring is advised.

Is IGF-1 DES and IGF-1 LR3 safe together?

Based on documented research, this combination is considered monitor. However, shared safety flags include: carcinogenic risk, insulin disrupting. Monitor accordingly.

What are the interactions between IGF-1 DES and IGF-1 LR3?

Do not stack with IGF-1 DES. Both are IGF-1 analogs acting on the same receptor. Choose one or the other based on whether you want systemic (LR3) or localized (DES) effects. This assessment has 90% confidence and is based on documented research data.

How should I time IGF-1 DES and IGF-1 LR3?

IGF-1 DES has a half-life of 20-30 minutes and IGF-1 LR3 has a half-life of 20-30 hours. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.
