Are you getting it from a pharmacy that makes prescription? Or like most only buy premade drugs?
As this makes a big difference. For hcg use one that makes it themselves. I was a pharmacy technician, for a while and did a lot of testing on potency, as we made are own drugs. Even through pharmaceutical routes we could not source hcg with any potency. The highest was somewhere in the mid 50s.(I don't remember exactly anymore). The worst sources were the standard sources of prepackaged/previaled hcg none were higher than 20%, one was legitimately 6%, (which isn't legal but the government doesn't care). That is what you would be buying from most pharmacy as they don't make themselves. You want to buy from a pharmacy that makes it themselves. Hcg also rapidly degrades and loses potency like within couple of weeks. Also ask if they get it in a refrigerator if not run like hell. Make sure to store what you buy at 33 to 34 Fahrenheit no higher no cooler.
