How To Use Injectables
FAQ
what you
need to know
What’s the best injection site for beginners?
The outer thigh (vastus lateralis) is often easiest for first-timers — it’s accessible, less nerve-dense, and easy to control.
Can I reuse needles or syringes?
Never. Always use a new, sterile syringe and needles for each injection to avoid contamination, infections, and blunted tips.
What’s the difference between a draw needle and an inject needle?
Use a larger gauge draw needle (18G–21G) to pull the oil, and then switch to a smaller inject needle (23G–25G) for a smoother, less painful injection.
How do I know I’m injecting into the muscle and not a vein?
After inserting the needle, pull back on the plunger slightly — if you see blood, remove the needle and try again in a new spot.
How often should I rotate injection sites?
Rotate sites every injection to avoid scar tissue buildup — glutes, thighs, and delts are all good options to alternate.
What should I do if the injection site becomes red or swollen?
Mild soreness is normal, but persistent redness, swelling, or pain may indicate an infection — consult a healthcare professional if symptoms worsen.
