Bros, deca and testosterone are great for bulking. The key is having a good diet and training your balls off. You should be eating at least four or five meals a day.
Bros, I would go with S4, 25 to 75 mg a day. That works perfectly. You can keep the dosage low if you worry about the side effects. There's no way to stop them.
Bros, you should be looking at using hcgenerate. It's great before I work out, during, or after. It will provide you some necessary herbals to help you grow.
