SU(2) with two Dirac ﬂavors in the adjoint representation (also called Minimal Walking Technicolor) is believed to be IR conformal. A possible way to see this is through the behavior of the spectrum. After deforming the theory with a mass for the fermions, one observes that a mass gap is generated. The masses of particles vanish in the chiral limit, while their ratios stay ﬁnite. In order to trust this analysis one has to relay on the inﬁnite volume extrapolation. I will discuss the ﬁnite volume effects, investigated by varying the size of the lattice and by changing the boundary conditions for the ﬁelds.
