IGF & Myostatin Pathway Kit
IGF signaling, satellite cell activation, and myostatin inhibition — the full cascade studied in published research
A comprehensive muscle-tissue research kit covering the full IGF/MGF signaling cascade as described in published literature. IGF-1 LR3 provides extended-activity insulin-like growth factor for sustained protein synthesis signaling, MGF and PEG-MGF are studied for satellite cell activation and new myofiber formation, and ACE-031 is researched for myostatin inhibition via activin receptor IIB binding. This kit enables study of both anabolic signaling and growth-limiting factor modulation.

What Studies Show
Observations reported in published research on the compounds in the IGF & Myostatin Pathway Kit research kit
Published studies observed improved recovery markers between training sessions and enhanced vascularity metrics. Weeks 3-4: Literature documented measurable strength changes and improved muscle fullness in study cohorts. Weeks 6-8: Peer-reviewed data reported visible muscle hypertrophy and modified body composition markers. Weeks 12+: Published research demonstrated significant lean mass and strength biomarker changes across extended protocols.
What the Research Shows
Peer-reviewed findings on each compound and their complementary mechanisms
IGF-1 LR3 is a long-acting insulin-like growth factor analog. Research shows extended receptor binding time compared to native IGF-1, with sustained signaling for muscle protein synthesis pathways (PMID: 11701431).
MGF (Mechano Growth Factor) is a splice variant of IGF-1 expressed in response to mechanical stress. Published research shows it activates satellite (stem) cells responsible for new myofiber formation (PMID: 14506268).
PEG-MGF is a PEGylated form designed for extended half-life. Studies show this modification sustains the satellite cell activation window from minutes to hours in research models.
ACE-031 is a soluble form of activin receptor type IIB that binds myostatin. Published research demonstrates that myostatin inhibition removes a natural limit on muscle hypertrophy (PMID: 20016012).
Research Dosing Reference
Dosing ranges cited in published studies — 4-8 weeks (cycle 4 on / 4 off) research protocol
IGF-1 LR3
MGF
PEG MGF
ACE 031
Research Protocol Notes
IGF-1 LR3 and MGF/PEG-MGF are best injected post-exercise into the target muscle group. ACE-031 is dosed less frequently due to its long half-life. Published protocols for this advanced stack reference lower initial doses with gradual escalation.
What's in This Kit
4 peptides, each with individual COA documentation
IGF-1 LR3
$54.95Direct IGF-1 signaling studied for muscle hypertrophy pathways
IGF-1 LR3 is a research peptide in the growth hormone / gh secretagogues category. IGF-1 LR3 is a synthetic 83-amino acid analog of IGF-1 (which has 70 amino acids) with an arginine at position 3 and a 13-amino acid extension at the N-terminus. MiPeptidos offers IGF-1 LR3 in 2 sizes with 99.5% verified purity and full analytical documentation.
MGF
$24.95Studied for localized muscle satellite cell activation
MGF is a research peptide in the growth hormone / gh secretagogues category. MGF is a splice variant of IGF-1 produced in mechanically stressed muscle tissue. MiPeptidos offers MGF in 1 sizes with 99.5% verified purity and full analytical documentation.
PEG MGF
$34.95Studied for systemic muscle recovery with extended bioavailability
PEG MGF is a research peptide in the growth hormone / gh secretagogues category. PEG-MGF shares the same mechanism as MGF (satellite cell activation, muscle repair, neuroprotection) but has been modified through PEGylation, which involves covalent attachment of polyethylene glycol chains. MiPeptidos offers PEG MGF in 1 sizes with 99.8% verified purity and full analytical documentation.
ACE 031
$13.95Studied for myostatin pathway inhibition in muscle research
ACE 031 is a research peptide in the specialty / research category. ACE-031 is a soluble decoy receptor consisting of the extracellular domain of activin receptor type IIB (ActRIIB) fused to a human IgG1 Fc domain. MiPeptidos offers ACE 031 in 1 sizes with 99.5% verified purity and full analytical documentation.
