Dadwag, Well I have no way to test besides keep running it and see how things go. The source I bought from is a buddy of mine who has run many cycles. The thing is it does have an expiration date thats still good. Is it possible that its maybe just underdosed? Since I have'nt seen any red injection areas, felt any lumps, or hot injection areas can I continue to use for the next few weeks until my other stuff comes in. The stuff I'm waiting on is from a different source. Thanks for the help
