Omna Pain-Can I switch to test E?

Stats:
33 years old
6'1"
228 lbs
17% bf

I'm doin my second cycle as follows
weeks 1-6 Dbol 3 tabs per day
weeks 4-14 Omnnadren 250 2 per week
weeks 4-14 Deca 1 per week
weeks 6-16 Winstrol 1 per week

I am in week 7. I think I'm getting a bad reaction to the Omna250. I shot my shoulder each time. First time I got a big red blotch on one arm and had fever for short time. Second time no reaction. Third time same as first.

Can I switch the omna250 to test E without any major problems????

Any Suggestions??????????????????????
