The injections do not have to be done in the muscle. I am in my 2nd very successful round of subQ injections. They are easy, (1 a day), safe, clean, painless, inexpensive, & effective. I cannot offer you any feedback on the cream, because I do not know anyone who has ever used it.
I am in TX also, (Dallas), & I was turned off by the clinics & what I perceived to be "HCG Spas" I checked out in the Dallas area. Hopefully, you've found a good, supportive & knowledgeable doctor.
