Mechanism of Action

Insulin binds to insulin receptors, triggering glucose uptake into cells, glycogen synthesis, protein synthesis, and fat storage. It's the primary anabolic hormone regulating blood glucose levels.

Research Summary

Discovery revolutionized diabetes treatment in 1921. Continuous innovation from animal-derived to recombinant human to analog insulins. Remains essential for Type 1 and many Type 2 diabetes patients. On March 26, 2026, the FDA approved Awiqli (insulin icodec-abae), the first and only once-weekly basal insulin for adults with type 2 diabetes, based on the ONWARDS Phase 3 trial program. Not approved for Type 1 due to hypoglycemia concerns.

Timing & Administration

Best Time to Take

Morning

Follow specific protocol

Food Recommendation

Take on empty stomach

Why This Timing?

Metabolic peptides often work best when taken in the morning to support daytime energy expenditure.
