There are a few vets on FB that are in the middle of a round or about to start one. It seems most of them are doing pellets b/c they are tired of shots. As for me, if I ever decided to give it another go I would stick with my injections b/c it's easier for me.
If you are looking for support on your journey you can try HCG forums or look up HCGers on FB. To find HCGers on FB just type in HCG and you should be flooded with people who have HCG in their names. Also, a good forum is www.4hcgsuccess.com or www.hcgdietinfo.com.
I started out on the latter site but moved with the other vets to the new site, the former.
