Works great and pretty quick

I’ve got a hard keeper. She looks so much better after taking this supplement. It really packed the weight on quick, and she’s maintaining once we went back down

I’ve got a hard keeper. She looks so much better after taking this supplement. It really packed the weight on quick, and she’s maintaining once we went back down to the maintenance dose. Could be a coincidence, but she sure is extra shiny too, and you can really tell she feels better. Great value, will definitely be keeping this in stock myself.
