What got worse for some people
In their own words
“The cycle went very well! I gained 6-7lbs and had very significant strength increases throughout.”
“I give the cycle like a 6.5/10. I loved the recovery + energy in the gym. But outside of that I don’t know if the gains themselves were quite worth the acne + restlessness.”
“This was my peak look in my opinion. very dense and hard, vascular, confidence was high. gym energy was unmatched. PR'd everywhere.”
“This was hands down my favorite cycle I've run. I gained 7-8lbs, greatly increased strength and improved my QoL immensely.”
“After one day I noticed an immediate cognitive and mood boost. Much higher energy than baseline, and a feeling of well-being accompanied with a very clear, focused almost nootropic feeling.”
“Noticed probably a 25-50% increase in the amount of volume I could recover from and intensity in the gym went up as well.”
