the new supplement on the market T stack RX no.17 is a specialist with this if you can afford it (see my sig for banner and codes) .. keep in mind a bottle lasts you 3 months if you take 1 cap a day so you pay a bit more but you get more also.. each cap is more potent in other words.
otherwise hcgenerate and hcgenerate ES work well too but you will have to take 2-3 doses of 2 caps a day.. EF has you covered either way.
