Research Peptide Starter Guide What to Know Before You Begin · Quality Markers · COA Verification · Storage · QSC
New to research peptides? This guide covers everything you need to know before purchasing your first research compounds — from what quality markers to look for, how to verify a COA, what supplies you need, and how QSC’s Janoshik verification works. All in one place.
Research peptides are synthetic amino acid compounds produced for in vitro laboratory investigation only. They are not FDA-approved drugs. They are not dietary supplements. They are research chemicals sold with research-use-only labeling for laboratory scientists and researchers.
Produced by Solid-Phase Peptide Synthesis (SPPS)
Supplied as lyophilized (freeze-dried) white powder in sealed vials
≥99% HPLC purity = research grade
Must be reconstituted with bacteriostatic water before use
Require cold storage (−20°C long-term)

Step 3: Verify the COA
For any QSC compound: visit verify.janoshik.com → enter batch code from your order → see HPLC purity, MS confirmation, compound name, test date. Directly from Janoshik’s database. No trust in QSC required.
Step 4: Basic Equipment Checklist
Bacteriostatic water (BAC water) — for reconstitution (multi-use)
Insulin syringes (U-100, 1mL) — for drawing reconstituted solution
Alcohol swabs — for vial septum sterilization
−20°C freezer — for long-term lyophilized storage
4°C refrigerator — for reconstituted peptide storage (up to 30 days)

Frequently Asked Questions
What do I need before buying research peptides?
Know: (1) Research use only — not for human consumption. (2) Quality = ≥99% HPLC + independent COA. (3) Need bacteriostatic water for reconstitution. (4) Need −20°C storage. (5) Verify COA at verify.janoshik.com.
What is the best peptide for a first-time researcher?
BPC-157 (extensive preclinical data, stable, well-documented) or Epitalon (40+ years Khavinson data, simple tetrapeptide) are the most straightforward starting compounds.
How do I reconstitute a research peptide?
Add bacteriostatic water slowly down the inside vial wall. Swirl gently — do not shake. Most dissolve in 30-60 seconds. Store reconstituted at 4°C for up to 30 days.
