We cannot use any take off procedure during a go around. However before we start any approach we have to calculate the relevant go-around climb gradients (both all engines and OEI) during the normal landing performance calculation (done on the EFB and documented on the OFP) and if we do not meet the required gradient either wait until our weight is low enough or divert. The performance calculation has to conform with a normal dispatch performance calculation (factors for dispatch) as the lowest usable value in all circumstances. In a 737 i never had problems with landing performance though, even in places like LOWS, LOWK or LOWI (special performance approval for all of those).
