Many will add hCG, lypo-c, or vitamins and reach the point where the volume is greater than 1 cc. You can pin more and still use the insulin .5 or 1.0.
OR, use a 3 cc syringe and inject 1.5 ml/cc combined medicine in a deep IM glut injection which for me is fast, and painless. The hCG is loaded first and the oils last. Not a drop of anabolics are left behind this way as the hCG acts as a flush.
1. uptake hCG using the 3ml with pre-fitted stubby. Discard needle and place syringe upright in pill bottle
2. uptake anabolic in a 1 cc syringe. Tuberculin syringes work great.
3. top load the 3ml with the anabolic. A pump of air will leave essentially nothing behind in the 1 cc syringe.
4. Fit 27 x 1-1/4 and inject.
As the oil-aqueous interface reaches the tip resistance will be felt. Increase thumb pressure. As the last of the oil-solubilized leaves the needle the hCG will rapidly dispense.
