No, it's not...
Few points:
- Use normal concentration. 100mg/ml for short esters, 200mg/ml for long esters. High concentration gear is painful.
- Unless you're very lean, glute injections need to be done with a long needle. A shallow injection will cause PIP.
- Avoid test prop, as the propionic acid is known to cause pain. If you need a short ester test, use Phenylpropionate or Acetate.
- If using UG gear, bake or pressure cook it for 20 minutes before using it. You'll not get rid of impurities, but will kill any possible bacteria.
- Before injecting, bring your gear to body temperature.
- Do not inject too fast. Use a steady hand.
- Ask your source what are the carrier oil and solvents used. Ask for specific amounts of every solvent in formula. Switch sources so you learn what your body likes and what it doesn't like. Some people have problems with EO, others with guaiacol, others with high BA, etc...
- Avoid quads.
