Insulin (reference)

Also known as Humalog · Lantus · many brands

Foundational peptide hormone for glucose control; abused in bodybuilding — extremely dangerous without medical need.

How to picture it

The master glucose-uptake key — opens cellular doors so sugar leaves the blood and enters tissues for fuel or storage. Included as a reference metabolic hormone so the atlas can compare research peptides against the real physiologic insulin story, not as a casual research chemical. Picture the body's primary "store and use glucose" signal.

Research focus & benefits

  • Primary glucose-uptake hormone reference
  • Metabolic comparison baseline for the atlas
  • Foundational endocrine glucose biology

Benefits describe research interest and pathway rationale — not guaranteed outcomes or medical advice. Research use only.

Overview

Insulin is the most important therapeutic peptide hormone in medicine. It is essential for diabetes care and catastrophic when misused for nutrient partitioning in sport. Any peptide database that skips insulin fails basic literacy — and any performance use without diabetes is high-risk.

Mechanism

Insulin receptor signaling drives glucose uptake, glycogen synthesis, and anabolism.

Research uses

  • Diabetes therapy
  • Metabolic research
  • Hyperinsulinemic clamps

Research dosing notes

Only under diabetes care plans or hospital protocols. Recreational use can be fatal.

Half-life / kinetics

Varies by analog (rapid to ultra-long)

Common research routes

Subcutaneous injection
Intravenous

Reported considerations

  • Hypoglycemia (can be fatal)
  • Weight gain
  • Hypokalemia
  • Injection lipodystrophy

Contraindications / cautions

  • Non-medical performance use
  • Inability to monitor glucose

Common research stacks

  • Carbohydrate co-ingestion in medical nutrition therapy — not DIY bodybuilding stacks

Legal / access note

Prescription hormone; criminal and medical consequences for diversion/misuse vary by place.
