HIIT - "minimum effective dose" & timing

What is the "minimum effective dose" of HIIT needed to reap the benefits? If I am doing 2 x 15 minute blocks per week, is that enough? I typically do Zone 2 followed by HIIT then resistance training then my first meal of the day (30+ grams protein), in that order. Thoughts?

Hypothyroidism treatments

Many docs only test TSH and supplement with T4 (Synthroid). I have had hypothyroidism for years. Currently, my TSH is low/below normal on Synthroid but my T3 levels are also low normal and I continue to have symptoms of hypothyroidism. When is supplementation with T3 recommended? How should appropriate dose be determined? When should complete thyroid panels (antibodies, etc) be considered?
