IGF-1 DES and Testosterone Interaction

Synergistic
Researched 95% confidence

IGF-1 DES and Testosterone have a synergistic interaction with 95% confidence. Testosterone increases IGF-1 receptor density and satellite cell number, amplifying the local effects of IGF-1 DES at the injection site. These compounds primarily affect different organ systems.

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.

Testosterone

Anabolic-Androgenic Steroid | Primary Male Sex Hormone

Testosterone exerts its effects primarily through binding to the intracellular androgen receptor (AR), forming a hormone-receptor complex that translocates to the nucleus and modulates gene transcription. This drives protein synthesis in skeletal muscle (anabolic effect), stimulates erythropoietin production in the kidneys to increase red blood cell mass, promotes osteoblast activity and bone mineral density, and regulates libido and cognitive function.
