Peptide Starter Checklist

• Peptide vial(s)

  Verify COA matches your batch before opening

• Bacteriostatic water (BAC water)

  10ml vial — NOT sterile water or distilled water

• Insulin syringes — 0.3ml or 0.5ml, 31G or 32G

• Alcohol swabs (70% isopropyl)

• Sharps container

  Or a thick plastic bottle with lid as substitute

• Peptide calculator bookmarked

  Use the calculator at /tools/retatrutide-calculator

• Small refrigerator thermometer

  Verify 2–8°C storage temperature

• Travel cooler bag

  For transport when away from home

• Extra insulin syringes

  Buy in bulk — cheaper per unit

• Notebook or app for tracking doses and dates

• Read the full guide for your specific peptide

  Dosing, timing, injection technique

• Verify COA batch number matches vial label

• Calculate your starting dose

  Use a peptide calculator — triple check your math

• Complete the health screening (contraindications)

  See: Can I Take Peptides?

• Choose your injection site and practice technique dry first

• Have a support contact ready

  Someone who knows you are starting a new compound

• Refrigerator confirmed at 2–8°C

• Lyophilized (powder) peptides in refrigerator or freezer for long storage

• Date label ready for reconstituted vials

  Good for 4–6 weeks after reconstitution

• Peptides stored away from direct light

• BAC water stored at room temperature (unreconstituted)

• No active cancer or cancer history (especially for GH peptides)

  Read contraindications for your specific peptide

• No thyroid cancer history (for GLP-1 peptides: Retatrutide, Tirzepatide, Semaglutide)

• Not pregnant or breastfeeding

• No history of pancreatitis (for GLP-1 peptides)

• No severe kidney or liver disease

• Over 18 years old

For a 10mg peptide vial + 2ml BAC water

NOTE — Concentrations change if you add more or less BAC water. Always verify with a calculator.
