According to me, Nu image medical is the best place for purchasing HCG injections online. They are 100% real prescription HCGC that are sent directly to your doorstep. Equally, they are not painful and does not carry any side effects. But in rare cases, it can lead to worst effects like swelling, sore, redness etc if not injected properly. Further, you may check their website for more detailed analysis on HCG.
