Just came across an article referencing a 2002 study titled: Prevention of Growth Deceleration after Withdrawal of Growth Hormone Therapy in Idiopathic Short Stature . The writer suggested an EOD protocol day split into 2 doses. First dose upon waking and second dose after workout. This allows the body to not build a complete dependence up exogenous GH and prevent tolerance and when cutting the cycle completely, allowing for the body to make a much quicker rebound. This study was done on kids using ED and EOD injections over 2 years using the same IU. On protocol was slightly better with ED BUTpost cycle recovery was MUCH faster and post cycle growth resumed a lot quicker resulting in a better outcome on EOD.
If you have an end date use EOD dose split into AM and PM post workout. If you plan on forever, then use ED whenever (once or split twice) as half-life is 12-24 hours for IM or SC injection.
