Some great success can be had with albuterol, IMO. It stacks quite nicely as part of PCT after Tren, or during a Tren cycle because of Tren’s bronchial side effects and thus restricts aerobic capability. But albuterol can combat this because it is an asthma medicine after all.
Further more sides with albuterol are quite mild, and controlable. Just be sure that when starting albuterol start slowly . If you don't you will more than likely feel your heart racing, not good...
