250mg a week at one injection a week is an inadequate first cycle. Go to the homepage and look at cycles. Check out the begginner ones. Stacking is also not recommended for your first cycle. Use the search button and look up first time cycles on this forum , it'll give you a good idea of what is and isn't a good first cycle. My advice would be if you're diets in order (check the diet forum or post it on here) And you've been training hard for at least 2 years, and you're at a peak you just can't get past would be run test e at 500mg a week split into a minimum of two injections. for 10-12 weeks. Also the half life of test e is 18 days i believe so vets correct me if i'm wrong that would be 18 days after last injection start PCT
