gropep igf lr3 question

i have access to this product but have heard so many conflicting reports im not sure what to do..........i was told if u buy it from a source and its already premixed its only good for about 30 days even if its refridgerated....so if the source has ad it for a monht already its not really still active......is this true or not..??.......is it better to buy the unconstitiuted version and mix it yourself...please advise.......and also....MC IGF1......is this a good product..?...

thnks

I have read some where that if igf is pre mixed it becomes unstable like HGH and if it were to be shook about to much it can be ruined, but then looking at all the posts on here about MC igf and the great results people are getting its got to be worth trying.

MC's IGF-1 is the real deal. they have it for a great price too. ive been on it for about 15 days and the pumps i get are unbeleivable. MC's IGF is really good shit
