hcg day 5. weekly injection Posted on March 9, 2014 by Emma Deangela 1 Comment me giving myself my hcg injection for the first time. One thought on “hcg day 5. weekly injection” I think in one of your videos you stated that it last for a week I never knew that you can inject every week I do everyday. So how much do you inject or should I say how many cc? and it looks like your injecting B-12 also. Comments are closed.
