Choosing Suppliers¶
Choose your source wisely.
Most sellers today are honest, but the peptide boom has attracted many who only care about profit. Protect your money and your health by learning the difference in 2 minutes.
Supplier Checklist: Red vs. Green Flags¶
Red Flags – Run Away¶
Avoid these suppliers
| What They Say | Why It's a Red Flag |
|---|---|
| "We only have manufacturer COA" or "We don't have COA under our shop name" | Anyone can download a fake COA from Google Images. They're not willing to verify what they're actually sending you. |
| "Third-party testing is too expensive" | They're prioritizing their profits over your health and safety. Real sellers invest in testing. |
| "I'm a seller but I'm using my own peptides and I didn't test but I'm still alive" | Just because nothing has happened to them yet doesn't mean it's safe for you. Would you wait for a catastrophe to happen before we start testing? |
| Takes longer than 24 hours to answer simple questions | If they're slow now, imagine needing urgent help with side effects later. |
| Gives wrong or vague answers about the peptide (half-life, storage, dosing, etc.) | They don't know what they're selling. This is dangerous. |
| Never asks about your health or experience level | They don't care if you're a beginner or have contraindications. Only profit matters. |
| Doesn't explain how they store peptides or dismisses storage concerns | Improper storage ruins peptides. If they won't tell you, they're probably keeping them on a shelf. Dead product = wasted money. |
| Goes silent after you pay or is hard to reach with questions after purchase | Support ends when the money changes hands? You're on your own if something goes wrong. That's not a business partner, that's a scam artist. |
Green Flags – These Are the Keepers¶
Signs of a trustworthy supplier
- Provides recent COA with their shop name on it (dated within the last 12 months)
- Purity on HPLC report is ≥99 %
- Answers technical questions quickly and correctly (you can double-check on Google)
- Transparent about origin
- Clearly explains how peptides are stored (temperature-controlled, protected from light/moisture) and provides storage instructions for you
- Remains responsive and helpful after purchase → willing to answer questions or troubleshoot issues
Your 60-Second Checklist¶
Do this every single time
- Asked for COA with their shop name and recent date → received it instantly
- Asked one technical question (e.g. “What temperature should I store Tirzepatide?”) → correct answer
- Took screenshots of the chat and the COA
- Checked the vial when it arrived
Stay safe
Buy from the right source → real results + safe experience.
Buy from the wrong one → wasted money + possible hospital trip.
