Just recently purchased this stack. Came from a legit source from what i have heard through diffrent people. I started it two weeks ago at 3cc's every 4 days after the third injection i noticed a great strengh gain but not to much in appearance, i bumped it up to 3cc's every other day now. Im down to one injection left and have noticed only slight appearance change but great strengh gains. Thinking of purchasing another to give it some more time to work.
