First to cover the end of the Tutu Challenge contest
I think we can either go with a picture comparison or you can go with a bf measurement type that you trust. Pics can be hard to tell especially if you are tanning now and were not then. You could always go to a college and get the hydrostatic test.

Actually I really want to do that one day. Oh wait I see in here you said they are bringing one in to your gym so you can get one done which is awesome. Out of all the tests that one is probably the most accurate but do it in the morning and don't drink much or it will skew your results. It will count the fluids in your stomach as LBM.
Any way you want to do it I trust you. With pictures I say make sure you are lean enough to see a relatively obvious difference in the pics does that sound fair? Considering as we said that 1% can make a huge difference .5% can make a pretty darn noticeable difference if in a picture we should not have to debate it much.
My honest assesment of the pics you have up now I would put you around 15% over or under by a percent, so the bf reading looks close to accurate to me. However I would put your starting pics closer to 25% than 20%. From the looks of it you had a lot of visceral fat that could not be measured with a caliper. I may be wrong and am simply going on sight. In either case, you are well on your way to a 6-5.5% Thor for Halloween. Also you could be lower and your skin being tight. Remember you are going to seem to lose LBM right now because you are dropping water like a bad habit. I warned you about a week ago to expect this due to less and less 1-Andro and increasing doses of EPI-V.
No real LBM is being lost but water weight is LBM because it is not fat mass. All of that being said to lose what looks to me like 10% in the last 8-9 weeks is phenomenal!!! Let's keep your eye on the prize here and keep moving. Remember you are not losing LBM that is obvious but water weight will skew the LBM levels, and you should expect that to continue to look like it is dropping even though the size of the muscle fiber is probably growing or at the minimum staying the same.
Also you were the biggest stud on the boat. Looking huge brother!
