hiya when i did my first injectable cycle i thought it wud be better to inject in quad aswell. i also was very nervous. i used a 26 gauge 1 inch needle i got very bad pain and my thigh swelled up. i cud hardly walk for a couple of days not nice coz u dont no what is wrong. then i switched to glutes with a 22 gauge and 1 half inch needle. its a little awkward but it was a hundred times better. a tiny swelling at first then i even looked forward to doing it. lol give it a try matejust make sure u inject slowly and keep things clean.
