Clean technique prevents most “TRT problems.”
Injection technique that reduces risk and improves consistency
Bad technique creates avoidable issues: irritation, lumps, leakage, bruising, inconsistent dosing, and unnecessary infection risk. This overview gives you a clean baseline process.
The non-negotiables (read this once, follow forever)
- New needle every time. No exceptions.
- Alcohol swab vial top + skin. Let it dry before you inject.
- Don’t touch needle tips. If you contaminate it, replace it.
- Consistency beats perfection. Same steps, same order, every time.
If you can’t do it cleanly, don’t do it. Reset and start over.

SubQ vs IM (simple overview)
Different people tolerate different routes. The “best” route is the one you can do cleanly, consistently, and comfortably—while keeping your outcomes stable.
Subcutaneous (SubQ)
- Common for peptides; used by many TRT users
- Typically smaller needles
- Can reduce injection anxiety for some
- May cause small lumps if volume/technique is off
Intramuscular (IM)
- Common traditional TRT route
- Can feel “cleaner” for some with oily solutions
- Requires good site selection and angle control
- Pain usually comes from bad technique, not the route
Pick the simplest route you can execute perfectly. Missed/dirty injections beat “optimal” theory every time.
Site selection & rotation (avoid irritation)
- Rotate sites to reduce inflammation and scar tissue.
- Avoid injecting into areas that are sore, swollen, bruised, or previously irritated.
- If you’re getting consistent lumps: reduce volume per site, slow down, and confirm needle placement.
For practical rotation planning, keep a simple log (left/right + date). “I’ll remember” fails fast.
Baseline injection workflow (sterile + repeatable)
- Prepare clean workspace (wipe surface, lay out supplies).
- Swab vial top and let it dry.
- Draw dose (use correct syringe/markings; remove big bubbles).
- Swab skin and let it fully dry (wet alcohol stings and increases irritation).
- Insert needle smoothly (don’t “jab and wiggle”).
- Inject slowly (fast injection increases pressure/irritation).
- Withdraw and apply light pressure (don’t massage aggressively).
- Dispose in a sharps container immediately.
If you’re rushing, that’s when you contaminate things or inject poorly. Slow down.
Common mistakes (and what they cause)
- Reusing needles → infection risk + more pain (dulls fast).
- Not letting alcohol dry → stinging + irritation.
- Injecting too fast → pressure, leakage, lumps.
- No site rotation → irritation, scar tissue, unpredictable absorption.
- Eyeballing dose → inconsistent results and “my protocol stopped working” confusion.
When to stop and get help
If you see signs of infection (increasing redness, heat, swelling, worsening pain, fever, streaking), don’t tough it out.
Technique issues are fixable. Infection risk is not a “wait and see” game.
