Hey guys , looking for a little help here , I'm coming off an overall win from a week ago , started my 15 week prep for North Americans .. So I need to come in at my best ... I uses one of the sponsors here on this board ., never had a problem with them and I will continue to use them . I need some Imput or reviews and or experience with other sponsor on here for specific products like Npp or mast propionate , primo , or even better a lean bulk stack .. I'm planning everything out and I'm wanting to go the lean stack route .. So you guys help would be very appreciate it .. I'm hungry for that pro card
