I am not familiar with their product. But I was put off by their site. They spend a great deal of time trying to convince people not to buy from someone else. I also called them some time ago when someone else asked about them. Their answers were vague, misleading and on occasion untrue.
They make several statements which just are not true. One example is that you MUST take b-12 on any hcg diet. Not true. Beneficial, yes, but not a must.
My daughter nor I took it at all. I lost 26 lbs, she lost 32. We did great.
With ANY homeopathic, (and yes celeste is homepathic though they dont say that very clearly, only after clicking through several pages), you must not eat or drink 15 minutes before or after taking. I have 25 years experience with homeopathy. Also, it is best to 'activate' it. Smack the bottle against the palm of your hand a few times before taking.
You can try it 6 times a day, space it out as evenly as possible, or try it the way you did before. As long as the total daily dosing is about the same it should be fine.
You will know soon enough if it is potent or not. Hope it works out for you.
