HCG while nursing

[Loriorioreo]

Okay, so....I am wondering if anyone out there can give any advice or share any info if they have heard anything about this.
I recently had a baby (well she is 8 months now.)  I breastfeed exclusively for 7 months, and am still breastfeeding now.  She is now able to take a bottle with formula as well as nurse. 
I am wanting to start the hcg again (I did it before I got preggo), and I am wanting to continue nursing while doing the diet.  I realize my milk supply may go down and that is fine, as she can take formula also.  I am hoping to still be able to nurse 2-3 times a day.
Does anyone know if it can be harmful to my baby at all?  I am wondering if toxins are released thru breast milk while losing significant weight.  I know that hcg itself is not harmful, as many mothers continue to nurse while pregnant.
Please if anyone has any facts or oppinions on this matter, feel free to share.

THANKS!!!
