Side effects

01Abdominal pain
02Nausea
03Fluid overload
04Polyp / neoplasia risk (intestinal; requires colonoscopy surveillance, not a boxed warning)
05Injection-site reaction

When NOT to use

  • ⚠Active or suspected GI malignancy
  • ⚠Pregnancy / nursing

Bloodwork to monitor

  • • Colonoscopy at baseline + intervals
  • • ALT/AST
  • • Magnesium / electrolytes

Common mistakes

  • • Skipping the colonoscopy schedule (polyp risk is real)
  • • Confusing GLP-2 with GLP-1 (different receptor, different indication)
  • • Using it outside short-bowel indication

Drug & supplement interactions

  • ⚠Polyp surveillance required, drugs that promote epithelial growth should be reviewed with provider
  • ⚠Affects absorption of orally-dosed medications (variable per individual)

is 250mcg of bpc enough for a knee injury?
For a knee, 250 mcg sub-q daily is the standard working dose and a solid place to start. The trick with BPC is consistency, give it weeks, not days. Inject close to the joint, run it 4-6 weeks, and don't drop below 200 mcg, it tends to stop cracking the threshold reliably down there. If it hasn't moved at all by week 3, that's when adding TB-500 earns its place.
how much bac water for a 10mg reta vial?
3 mL is the standard play for a 10 mg reta vial. That's 3,333 mcg/mL, clean unit math across the titration: 2 mg = 60 units, 4 mg = 120 units, 6 mg = 180 units on a 100-unit insulin syringe. Run 2 mL instead if you want fewer, more concentrated shots (5,000 mcg/mL, so 2 mg = 40 units). Since most people titrate up over ~12 weeks, 3 mL keeps the numbers cleanest.
what should i track on bloodwork for tirzepatide?
Lipid panel, ALT/AST (liver enzymes), and an A1C, baseline before you start then every 3 months. If you've got metabolic-syndrome history, add fasting glucose and insulin so you can actually watch insulin sensitivity improve. You don't need a big hormone panel for a GLP-1.
