I'd highly doubt it is better than PM, from my understanding and reading, PM is honestly the best you are going to find, and at 20.00 from ainterolherbs.com its unbeatable price/quality/effects takes a lil time for the breast growth to kick in with PM but with time comes quality, all those who I seen who use PM in their regimen, have incredibly beautiful breasts, shape, size etc. Those who use just herbs from walgreens and such tend to develop much slower and more moobs then boobs. PM will give you the fullness, roundness and protrusion of a female breast.
PM will also cause changes to your hips and buttocks by redistributing fat to those areas narrowing waist as well but that as well takes time but a very nice effect, only warning i'd say with PM though, is if you plan on having kids, or having sex, think wisely, for some, me especially PM has caused impotency till i quit taking it, as well as visibly shrunk my testes and quality of sperm. Not that I mind but i quit just for sexual function purpose, then again their are herbs to balance that as well suchas Stinging Nettle, Zinc, and Superba Beta.
Sorry so long just thought i'd relay longterm info as well hope it was helpful somewhat
