Working already
I have been using these for only about 2 weeks and already I'm seeing a change. I'm rather flat-chested but these are really starting to make me develop. I thought i was going to have to resort to Hormone therapy or other means but I'm loving the results.

From A to B that’s the Goal!
Overall I love this product I am 22 years old and I have been in a 32 A cup my entire life. I have been using this product for two months along with Wild Yam Root vitamins and my breast have gotten fuller and rounder. Now I haven’t went up a full cup size as of yet. My chest is very small so I imagine it’ll take at least 6 months for the look I actually want. However I do highly recommend this product. I haven’t finished my second bottle but my breast are much fuller than ever. I do see reviews about the effects not lasting so I will review again after I get the look I desire.

has anyone gained weight on this product?, also does this affect birth control?.
A shopper on Sep 11, 2012

I am considering buying this product but have a few concerns...
is this a product that is specifically targeted towards breasts, or will I gain weight in the rest of my body? That would be my main concern because I am trying to maintain the weight that I am now and don't want anything to hinder that. Also, are there any side effects that have come up that aren't stated on the website?

An answer to both of these will be helpful, because I may buy the product this week.

Thank you very much.

Once you get to the bust size you want, can you stop taking it? Or will I have to take it forever? And how long will it be before I see anytime type of results.

i have been taking natural curves for 4 weeks and i noticed the difference in my breast after the 1st week, but now my breast seem to have changed back to before i started taking the natural curves and also feel more flabby then before. is there any reason why this would be happening?
A shopper on Jun 11, 2013
BEST ANSWER: It usually takes about six weeks to achieve the full effect of the supplement. That being said, it sounds as if you have lost some water weight. This tends to happen with herbal proprietary blends. Try increasing your fluid intake to at least 8 - 8oz glasses per day, which is the recommended daily intake.
