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.

What you actually get out of it

  • ✓
    You ask any question about your own stack and get a real answer

    The AI Coach reads your saved protocol on every message. Ask it your dosing math, whether two compounds clash, or what to do next. Plain English, trained only on Pepdex content, won't push vendors, won't pretend to be a doctor.

  • ✓
    You handle a missed dose without Googling it

    Tap 'Missed a dose?' on any entry. The Coach pulls your stack and tells you whether to skip, take it now, double the next, or just resume, based on the peptide's half-life and what you're running.

  • ✓
    You stop keeping your protocol in your head

    Save your stack once and it's there on every device, your schedule, your doses logged, the whole thing in one place instead of a notes app and three screenshots.

  • ✓
    You never get caught off guard by a vial running low

    Personal Stack auto-calculates how many days each vial has left and surfaces the low ones, so you can reorder in time instead of finding out when you go to draw your next dose.

  • ✓
    You get the Verified Peptide Sources desk

    A members-only reference for vetting what you run: how to read a Certificate of Analysis, what third-party lab testing should show, how to tell research-grade material from junk, all tracked across real member orders. Pepdex doesn't sell or ship anything; the desk gives you the diligence to judge any source with confidence.

  • ✓
    You ask the Coach to compare your options for you

    Ask it Tirz vs Sema, BPC vs TB-500, Sermorelin vs CJC, for your goals and your stack, and it answers in context instead of you holding 30 tabs open. The comparison pages stay free to read; the Coach makes the call personal.
