Paddock is a good company. You shouldn't have noticed any difference. I have been using Watson without any problems. The package insert from Watson states, "Each ml contains: Testosterone Cypionate 200mg, Benzyl Benzoate 20%, with Benzyl Alcohol 0.9% as preservative in Cottonseed Oil."
The Paddock package insert states, "Each mL of the solution contains Testosterone Cypionate, 200 mg; Benzyl Benzoate, 0.2 mL; Cottonseed Oil, 560 mg; Benzyl Alcohol (as preservative), 9.45 mg." The Paddock brand has an extra 0.45 mg of Benzyl Alcohol per ml. Shouldn't be enough to make a big difference.
