Without seeing how the OP was responding to nutrition and training for a while, I can off hand mention a few things:
1- Are you retaining water from the test? Some people can hold a lot of water from various esters, not sure if the gel has similar effects.
2- I’ve worked with a good number of assisted athletes in the last few years, and I’m amazed that I often have to diet/cardio them harder (lower cals, more cardio!) than most of my natural competitors… Honestly, this surprised me a lot, coming in with my science is science approach -lol
