hello. bought some clenbuterol and peptides. currently on the way in the mail.

haven't injected shit before so this will be a first.
what kinda needles/syringes/medical equipment do I need?

I am using the ***services.com website for their medical equipment because they have hospital grade stuff.
however, they have a bunch of different options on the needles and syringes and everything

which kind is the least painful?
which kind doesn't leave track marks and stuff?
how much will I need to do like 8 weeks worth of injections
3cc's 5cc's what does this mean


also do you guys have videos on how to inject

?

does it need to be done into the vein or muscle or fat or what


thanks
