Conversely, one should always ramp and taper T3, to acclimate and reacclimate your thyroid gland/feedback loop to the horomonal increases and decreases respectively.
Just want to add t3 can be cycled in the following manner 25 mcgs up to 75 mcgs. I usually do well just staying at 50 mcgs for the duration then tapering down for a week at 25 mcgs.
