"i was on the shot about 2 years ago, it  did in fact add on a few pounds but it was effective.. i spotted for about 20 days and i was gucci. i never went back for a second shot due to my financial situation but it kept me infertile for an additional 10 months( not complaining, it was great). i just recently went back to get the shot again... it all depends on you! and p.s it heightened my sex drive. to each it&#039;s own"
