I'm looking to gain lean mass and get cut. I have had panic attacks in the past and actually found that I have a thyroid that is underactive. I am hoping to find something that is fairly safe as far as sides.
Be aware that recomping (what you want to do) is going to be VERY dependent PRIMARILY on the MANIPULATION of your NUTRITION!
Once you have your nutrition (AND training) sorted, then you can look at supplements.
Based on your goals and comments, products that would be beneficial to you IMO would be a natural Testosterone booster/stack (increases free and total testosterone) and a thyroid booster, an insulin mimetic optional.
Since you have not used anything before, you are best off starting out with only one or two products. One of the best stacks for you IMO would be Erase and Alpha-T2 - or Shift instead of Alpha-T2, if you are sensitive to any form of stimulants.
A stack like Erase or FREE TEST/IGF-2 or HGHup/Drive/NeoVar Recomped is something you might want to consider in the future, once you have used a more simple stack (note that "simple" does not mean any less effective).
