I moved to a new home about a year ago and recently finished unpacking some stuff. I have what was a new bottle of test enanthate,10 ml which somehow came unsealed at the top(the plastic cap on top). The injection membrane hasnt been pierced or puntcured, but the color of the test has changed from a pale yellow to a darker shade . Its kinda like a really watered down iced tea color. Could this be caused from heat or could it be unsafe to use. The expiration date is good for dec 2013. I hope to use it but im kinda worried. Some good input from someone with more expierience than me would be greatly appreciated.
