I can vouch for Spawn's effectiveness on a cutting cycle. I'm 4 weeks into what will be an 8 week cycle and I've ramped up my cardio just a bit and have already gotten pretty cut up with a clean diet at or just below my normal maintenance intake. Can't speak to the Methyl XT though. Strength has continued to rise on the Spawn even though I've dropped 8 lbs. in the past 4 weeks. Side effects have been mild so far. I did 3 caps/day for the first 3 weeks and bumped up to 4 caps/day this week and, assuming the sides don't get alot worse, I'll keep up the 4 caps/day for the remaining 5 weeks of the cycle.
