Peptide Starter Checklist
Everything you need before your first injection. Work through each section before starting any peptide protocol.
Tip: Save or print this page and check off each item before your first injection. Rushing is the most common cause of mistakes.
Supplier Verification (Before You Buy)
Ask for the batch-specific COA
The certificate tied to the exact batch you would receive. A refusal or a generic PDF ends the conversation
Confirm the lab is real and independent
Look up the laboratory named on the report. It should exist outside the listing and have no stake in the sale
Match the batch number and read the report
Batch number matches what is being sold, identity confirmed by mass spectrometry, purity measured by HPLC
Read community reviews and history
Reputation you can verify off the seller's own channels, not testimonials on their site
Test customer support responsiveness before ordering
Ask about cold chain
Packaging, cold packs, and transit time. Vague answers mean the vial may not match its certificate on arrival
Confirm seller identity and written terms
A traceable name and history, plus written return or replacement terms. Only then does paying make sense
When the vial arrives: verify the COA batch number matches the vial label

Essential Supplies
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
Nice to Have
Peptide calculator bookmarked
peptidesvietnam.com/tools/peptide-reconstitution-calculator
Small refrigerator thermometer
Verify 2 to 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
Before First Injection
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
Storage Setup
Refrigerator confirmed at 2 to 8°C
Lyophilized (powder) peptides in refrigerator or freezer for long storage
Date label ready for reconstituted vials
Good for 4 to 6 weeks after reconstitution
Peptides stored away from direct light
BAC water stored at room temperature (unreconstituted)
Safety Screening
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)

Quick Reference: Reconstitution
For a 10mg peptide vial + 2ml BAC water:
| Desired Dose | Volume to Draw | Syringe Units (100IU) |
|---|---|---|
| 250mcg | 0.05ml | 5 units |
| 500mcg | 0.1ml | 10 units |
| 1mg | 0.2ml | 20 units |
| 2mg | 0.4ml | 40 units |
Concentrations change if you add more or less BAC water. Always use a peptide calculator to verify.

Once you've worked through all items, the remaining decisions, the dose, the titration pace, and when to begin, belong with a licensed prescriber. The educational principle behind every approved protocol is the same: start low and build gradually.
