hcg filling syringes Posted on March 29, 2014 by Emma Deangela 2 Comments Please visit our website for mixing kits and where to order hcg http://hcgdietforyou.com/ 2 thoughts on “hcg filling syringes” You should inject air into the vial before you withdraw the liquid. I’ve had my LUPI HCG mixed for 42 days now and it is still good. Thank you for your comment. Perhaps LUPI is more stable than Hucog. Ours continues to go bad at about 10 days. Comments are closed.
