Hi, I've tried this and blackmore conceive well gold when I was ttcing. It's ok for me without side effects. I also tried chicken essence for pregnancy plan to nourish my egg. I also asked hubby to take health supplements and drink chicken essence for men as well because ttcing needs both you and hubby's efforts. I got pregnant successfully after ttcing for 6-7 months. The chicken essence for conceiving is going to have promotion, maybe you can consider about it because the price will be more reasonable. Good luck! http://www.qchicken.com.sg/30101211-tian-yuan-xiang-anniversary-mega-sale-limited-time-offer-15off
