Legit blue hearts are available, I have bought bunk before though. March pharmaceutical 10mg is what you are after, back pumps, water retention, BP and more plates added with size.... Yeah it is legit
one guy posted that he and 4 other of his friends had no gains. Others here who also ordered and used those same blue hearts reported gains. me5150 I think is the name...used blue hearts from DS for 4 weeks and in the 5th week he was up 18 lbs.
You think one bottle was bad out of 20-30 bottles?
There are a lot of variables and we can never know them.
