No, and yes. If it's legit clomid, you would not. There's a small chance tho ordering from Research Companies that sometimes you either get a bad batch, or it's underdosed, or a thousand and one other possibilities of something being off... it doesn't happen often, but it does happen from time to time. Because of this possibility, I'd recommend supplementing a little extra to the PCT to make up for any possible holes, so running something like DAA or Ultra Male+Anabolic Matrix in conjunction with your clomid during PCT would increase every possibility of a full and solid recovery
