Staying safe
Things people sometimes notice
- A sharp, spicy sting for a minute or two as you inject, worse when the solution is concentrated
- A small welt or itchy bump at the site that fades within a day
- Blue liquid in the vial, which is the copper and is correct
- A wave of nausea or feeling lightheaded if you jump straight to 5 mg; drop back and it clears
Stop and get help if (trouble breathing or swelling: call 911)
- Hives, swelling of the face or lips, or trouble breathing
- A rash that spreads beyond the injection site or a reaction that gets worse with each dose
- Persistent nausea, metallic taste, or stomach pain that does not settle at a lower dose; that is too much copper
Talk to your doctor first, especially if
- You have Wilson's disease or any copper-handling disorder; this is the one real contraindication
- You are using prescription retinoids or other strong actives on your face and plan to layer a topical on top; the combination can irritate
- You are pregnant or nursing
- You have cancer now or have had it. These peptides push growth and repair signals, so this is a hard stop, not a judgment call.
Mixing it
Here is the math for a 50 mg vial mixed with 3 ml of bacteriostatic water (the most a standard vial takes), taking a 2 mg dose.
Bring the vial to room temperature and clean the top with alcohol.
Add 3 ml of bacteriostatic water slowly down the side, or more if your vial holds it.
Swirl gently. The solution turns a clear blue, which is normal for copper peptides.
Store in the fridge, away from light.
Use within about 3 to 4 weeks once mixed.
