Last cycle while on Tren my sleep was horrible. Constant insomnia...had to take Tylenol Simply Sleep every night. This cycle I'm on Tren and Winstrol and I'm sleeping like a baby....winny gave me bad insomnia before also. I don't know whether I'm just training that much harder and my body can't help it but to sleep, or perhaps my body just got used to these two compunds since it's my second time using each.
