Focus peptide
Tesamorelin
Visceral fat, growth hormone axis
Grade A
Contraindications — do not use if
  • Active malignancy — growth hormone is mitogenic and IGF-1 is a growth signal
  • Pituitary disease, pituitary surgery or head irradiation
  • Pregnancy and lactation
  • Diabetic retinopathy
Insulin and sulfonylureas
Caution / monitorGlucose & diabetes meds

Tesamorelin worsens insulin sensitivity; glycaemic control may need adjusting.

Corticosteroids
Caution / monitorHormonal & GH axis

Blunt the GH response and add their own metabolic burden.

GHRH analogues (CJC-1295)
Caution / monitorHormonal & GH axis

Same receptor. Stacking adds risk, not effect.

Interaction categories and severities are inferred from published notes and are not a substitute for a clinician review. Absence of a listed interaction is not evidence of safety — always cross-reference for any drug you take.
