Dude you just bought finaplix. you need to know exactly how to make this because you are extracting the trenbolone from the rest of the crap. Sounds like you paid way to much.
The next problem is you need test with it. If you use tren by itself, you will have a limp dick, no libido, and many other problems. Tren can cause gyno thru prolactin so you need to have some caber or prami on hand in case of gyno or leaking nipples.
You should not be using tren to begin with. Tren is very strong and can produce some of the worst side effects. Your friend is an asshole for selling that shit to you. If you want to do a cycle you need to learn about what you are doing. You plan on making this and injecting it and have no idea how or what it even is. Bad idea. This is why steroids get a bad name.
Time to rethink your plan. Do you have filters to make it sterile?? They usually don't come with the kits and agin you need to know what you are doing to make it safe and sterile.
