10 Common Mistakes New Peptide Users Make
From bad math on the calculator to skipping bloodwork — here are the mistakes that waste money and delay results.
1. Buying from sketchy vendors
If a deal seems too good to be true, it is. Bad sourcing wastes money and can be dangerous. See our guide on where to buy peptides safely.
2. Wrong reconstitution math
Adding too much or too little BAC water means every dose is off. Use a calculator — don't eyeball it.
3. Shaking the vial
Peptides are fragile. Swirl, never shake.
4. Storing reconstituted peptides at room temp
The fastest way to ruin a vial. Refrigerate immediately after mixing.
5. Stacking too many compounds at once
If you start 4 peptides on the same day and feel weird, you have no idea which one is responsible. Add one at a time, 2 weeks apart.
6. Ignoring titration on GLP-1s
Starting at a high dose causes brutal nausea. Ramp slowly.
7. Not tracking anything
Without baseline measurements, you can't tell if anything is working. See what to measure.
8. Skipping bloodwork
Especially on long-term protocols (GH peptides, GLP-1s), bloodwork is essential.
9. Reusing needles
Don't. Each shot = fresh needle. Used needles dull immediately and harbor bacteria.
10. Not having an exit plan
Especially with GLP-1s — what's your maintenance plan when you stop? Plan it before you start.
