I got some growth from a trusted sponsor on this site and the shit stings when I pin it......not to mention I was sent green tops when asked for blue tops. :banghead:
I use rips and its never stung once. i shoot 10 iu 5 mins after mixing too at the moment. mayby try a different supplier for bac water, perhaps its some sort of fille in your gh
It should only hurt your wallet
How soon are you injecting after mixing? I have a friend who was having the same problem started mixing the night before and the pain went away
