this is my second order from them very happy with company and product(only used there hcg) There a bit more pricey than other sources but i like the easy payment and delivery, im using it for research purposes so its legal to. like the 1000 iu doses keeps from wasting product, my test subject uses 500iu week and once reconstituted not supposed to be kept over 30 days so the common dosed vials at 5000 iu dont make sense
