Getting answers, you have done excellent troubleshooting by trying both Testosterone Cypionate and Testosterone Enanthate to narrow down why you are having a local reaction to these medications. You are also correct that it's impossible to create a "jet" of oil with a syringe due to the fact that the liquid is too viscous and the needle bore too small to create a sufficient flow rate.
Any one of the ingredients in Testosterone Cypionate, which include Cottonseed Oil (carrier oil), Benzyl Benzoate (solubilizer), or Benzyl Alcohol (preservative) might cause the reaction. Since you already tried Testosterone Enanthate, which uses a different carrier oil (Sesame Oil) and preservative (Chlorobutanol) and still had the same local reaction I would say that it's not the carrier oil, solubilizer, or preservative that is causing it. It's doubtful that changing the oil is going to make any difference. Your body just doesn't like subcutaneous injections of oil-based testosterone. This is a common side effect for patients doing SQ injections of testosterone.
Gene, Bass and Jasen are correct in trying a different injection site (like your hip or buttocks), using a 29G 1/2'' syringe and/or using smaller, more frequent doses to solve the issue. Some use 27 gauge 1/2 inch on shoulders also.
If these solutions still don't fix the problem then I recommend doing intramuscular (IM) injections. If you have the same problem with IM injections then it's a good idea to use a different dosage form like Testosterone Cream.
