Im very interested in doing a 6-8 week cycle of sustanon and/or deca-durbolin. I have a couple of questions and want to get some information and opinions. Which steriod is safer with less side effects and packs on more mass in that 6-8 week period? In your opinion what is the safest steriod out there and what is the most effective/strongest steriod out there? What kind of stack would you recommend for a 6-8 week cycle for the best results and safest outcome?
