Yes, and I still cringe. From my perspective as a medical provider, the benefits of an AI outweigh the risks of using and not using an AI as long as doses are properly followed and not misused or abused. I agree, there is certainly an optimal range of E2 and it varies individually. Some guys feel better when their levels are on the higher end of normal (ULN); others function better at the lower end. I've had mine run as high as 400 and I've accidentally crashed it trying to lower it quickly (when it shot up). Ironically, I felt no untoward effects at 400 although parameters in my blood work favored cardiac risks if left untreated. Crashing my E actually "felt" worse.
Good to hear the stress test was normal. Keep an eye on the BP and hyperlipidemia when running any cycle - we want you healthy and alive.
Diet is also an individual factor but it is critical to success. The TDEE an caloric needs for LBM or cutting will vary with each person. The TDEE+/- 500 to gain or lose weight is a guideline. Everyone needs to determine their own "set point" for sustainable gains or loses - but make no mistake, nutrition is everything.
Like many guys, I made the mistake in my very first cycle of not staying consistent with my nutrition off cycle. I gained a lot (mostly water) on my very first cycle and lost much of it when I went on TRT because I wasn't eating enough to support and sustain the gains. We're just trying to help the newbies avoid the mistakes we (an others) have made.
