For me personally it did not make any difference so far. I relocated and had to switch from Swansons BO to Source Naturals Raw Female, which contains synergistic complex of 200mg bovine ovary and 200mg bovine uterus. I had some growth with Swansons BO first month (herbs did not work for me at all, just messed up my cycle), but then I ran out of Pituitary and next cycle there was no growth (bovine dose was same with both brands). For some time I was mixing remaining Swansons BO with SN, but with no pituitary, so I blame it for now
Waiting for pituitary and l-arginine now, will update you if notice any difference.
