Not steroids but L-carnitine prescribed by marek health. Pretty sure I injected correctly but just to make sure

1.found spot on quad muscle 2.wiped clean 3.got needle,removed air, got correct amount of meds 4.stretched skin and inserted at a 75 degree angle. Idk why but that felt comfortable to me 5.checked but no blood 6. Continued to insert and slowly injected liquid meds. It felt warm going in PAUSE 7. Pulled out (nice) and saw a tiny bit of the liquid come out and a tiny drop of blood 8. Feelin good I thinks

So now I got a 3 questions. 1.did I do good? 2.can the quad handle 250mg or 5 CC’s of this 3.what to change or know in the future

Thank you in advance :)
