First and foremost, use only one legal steroid stack at the same time. Different stacks are meant for different goals, if you think you have more than one goal then choose which one you think is better. For most first timers, this becomes an issue since losing fat & gaining those lean muscles are deeply coveted that they tend to be in such a hurry. This is where the saying patience is a virtue comes in. Rushing to lose weight has never been a good idea. It may give you your desired results for a temporary time and will just cause more harm than good. It is best to take it one step at a time. One stack at a time is advisable as it will help your body in achieving its goals safely. Using more than one stack has the tendency to decrease the effectiveness of the product and once you decide to stop using these stacks, your body will just return back to its old figure or worse. Taking time will ensure that your body is well-adjusted with the progress and therefore ensure that it will accept all the changes.
