Oftentimes, females snakes and lizards also have the ability to control whether they get pregnant immediately after mating or not, to account for the fact that the ideal time for mating may not translate to the most optimal time for ovulation and gestation. Consequently, females can store sperm internally  for as long as five years, or possibly longer.  This phenomenon is known as cryptic female choice , as the physiological mechanisms making this possible are hidden within the body, and the female has the ability to influence when egg fertilization occurs.
It was pure luck that found me in the Czech Republic, which is where my now-fiance happened to live. You don't get lynchings here, you don't have people beaten in the streets here, and the suicide rate is much lower. People don't even yell at each other. The first week I was here, I saw a gay couple holding hands on the train and nobody gave a shit. Everything is still expensive, because I've only been here for one year and I'm not a citizen yet, but it's significantly less expensive than in North America. It's like leaving your horrible small-town high school for college in the big city. I used to get bullied all the time, and now I'm the Fonz.
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
