Typically, an item to pulse is one that has the potential for some rather harsh short and long-term side effects. Liver toxicity, shutdown, gyno - all are the sides that we try to avoid by pulsing. While you're not getting the dose all the time, and rather only when you need them (in theory), the chance for those sides to present themselves is greatly decreased due to the overall length of time in your body being shortened through the pulse.
In the case of 3-AD, though it is quite potent, the side effects from it are so mild when seen at all that pulsing it simply isn't necessary. Even if one was prone to gyno or hair loss or anything else, as long as you follow the recommended dosing protocol with regards to length of cycle, dosing, and PCT, you should have no troubles from it whatsoever. Being a non-methyl also is a huge bonus!
If I were you, and eventhough you are only pulsing Hema-, I would still wait the obligatory time off to clear your system. After that, start fresh with 3-AD for a bottle or two - 22.5-45 days - and see how you feel about it. Don't forget to pick up aPCT while you're shopping!!
Best of luck to ya! :cheers:
