I JUST STARTED SEO AND THIS IS THE END OF MY SECOND WEEK AND I HAVE BE INJECTING VERY SLOW AND I NOW HAVE HARDNESS IN MY BICEPS.I HAVE BEEN MASSAGING LIKE YOU SAY IN YOUR ARTICAL ON HOW TO USE SEO WHAT DO YOU RECOMMEND I DO.
Sounds to me just like swelling. Your body should get used to it after another shot or two. Its just reacting to a foreign substance. I swell a little bit after every shot I take, its not noticable in large muscles but biceps, triceps, shoulders and calves its very noticable the next day.
