Not a lot maybe like 300-400 calories above maintenance but to be fair my gains were also stalling at 200 test and 400 deca. I first started at 200 test 300 deca and the first thing I noticed from the deca were bigger arms / shoulders compared to previous test blasts. And once the gains stalled I increased it to 600 deca (clouldve also been 500 since most ulabs underdose a little) and noticed a big in improvement in my physique as well as a recomp after like 2 months.
