I think you have deca slightly confused... deca does not provide any sort of real healing.. it can mask a wound lubricating joints but it doesnt actually heal anything and by masking an injury, often times it can make it worse... it also does not necessarily give you an appetite increase... it could but its not something i would just expect.. MK677 will give you a huge appetite increase and will also give REAL healing so you will actually heal and make progress...
