Quiting Deca only cycle: PCT? Side Effects?

Hey everybody let me thank you for your dedication to this site.

In true newbie fashion I rushed into my first cycle under educated. I am on my first week of a 300mg/w Deca only cycle. I have decided to stop the cycle. I am going to research and get prepared before I try again.

Questions:

Do i need to consider any therapy?
I took one 300mg dose of Deca last thursday night and nothing else.

Should I worry about any side effects from the single dose?

Is their anything I can do to prolong the shelf life of an oil based compound?

Thank you

dont worry ull b very fine 3oo mg will not make any difference it will not harm u by any mean

Just store you stuff out of direct sunlight and in a temp controlled environment(not too hot not too cold) and it will be fine. I would place it in some type of air tight container since you have unsealed the vial.

Thanks I am glad I found you guys because I was heading in the wrong direction.
