I use the Gh for 6 months at a time. I run the T-3 for the entire time at 12.5 per day. I have tried pyramiding the T-3 before when using GH for 4 6 weeks at a time starting at 25 for the first 5 weeks then the last week working doen to 12.5. Then waiting 6 weeks and doing it again but this time using more, starting at 25 then working up to 50 then to 75 then back down to 50 to 25 then 12.5 for 6 more weeks. Slin I will use for 5 weeks at a time. then off for 5 weeks then on again. I run test the entire time except going into the 3rd month I use Tren instead.
