I'm not sure but a few weeks after starting Deca I became really tired all the time. I seriously never feel like working out or doing anything. This is ridiculous. Has anyone else ever felt this? By the way I dropped the Deca in after 11 weeks so I know that it isn't the Test. That made me feel great. I can't take any stimulants: clen, ephedra, caffeine, etc. I have some Acid Reflux and I believe I may have an ulcer... but anywas... they effect it way too much. Is there anything else I could take that would give me some decent energy? THanks.
