FGL vs Dulaglutide

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

FGL

FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.

Dulaglutide

Dulaglutide (Trulicity) is a once-weekly GLP-1 receptor agonist for type 2 diabetes. Its larger molecular size from fusion with an Fc fragment extends half-life and may reduce some GI side effects.

Side-by-Side Comparison

AspectFGLDulaglutide
MechanismBinds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival.GLP-1 analog fused to a modified human IgG4 Fc fragment, providing extended duration of action. Activates GLP-1 receptors for glucose-dependent insulin secretion and appetite suppression.
Typical DosageResearch protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established.Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response.
AdministrationSubcutaneous injection or intranasal administration. Research compound with limited human dosing data.Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens.
Side EffectsLimited human data available. Animal studies show good tolerability.Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration.
