You're going to do a 10 week cycle of 400mg Testosterone per week, which will look like this:
* 0.5ml Testosterone TWICE per week.
So for example, if you took your first injection on MONDAY, you would use THURSDAY as your second day. And repeat.
Hold onto your Tren Acetate for a future cycle. We want to keep things simple, you will grow very well on very little since it's your first cycle, and you don't really have enough Tren to make the most of it on a 10 week cycle.
Now, let's get the injection basics down:
(1) You need a fresh sterile needle for each injection, and one to draw up with. So 2 needles per injection. A minimum of 10 to inject (either 25G or 23G) and 10 to draw up (either 23G or 21G). I advise you to buy spares in case of mistakes. NEVER re-use a needle.
(2) You need a fresh sterile syringe for each injection. NEVER re-use a syringe.
(3) You need Isopropyl Alcohol Pre-injection swabs to sterlise both the injection site and the top of the vial each time you use it.
Let me know if any of this confuses you.
