If the half-life of enantate, cypionate and deca is longer than 7 days why inject more often then every 7 days. Has anyone here ever tried injecting deca less often than every week? Does anyone have a good reason for injecting more often than every 7 days? For my next cycle that I start on monday I am going to experiement by taking lower dosages, but more often. I'll track the results and share them with anyone who is interested.
