Medroxyprogesterone
"Honestly everyone's bodies work differently and I've heard horror stories about every type of birth control but this one has been really excellent for me. I've been on the depo shot for 5 years now (planning on switching soon). The shot does sting a bit so be sure it's injected into your hip instead of arm. First month I spotted nonstop, but I haven't had a single period since. No pregnancy scares. Very gradual weight gain for me, 25 lbs over the past five years. Cleared up my acne, have plenty of libido. I give it 10/10."
