Just curious, other than looking for changes in the mirror, are there any other indicators that would tell me it’s working? I only ask because on SLU I felt a noticeable difference in my endurance during cardio sessions… On Tirz, my appetite tanks… Beta Alanine makes the fingers tingle.. Know what I’m sayin? A

I can’t find any definitive answers on (A) whether SLU needs to be cycled, and (B) if so, how long a cycle length should be. Any insights?
