First of all you are 27 ....but with your shoulder and an extremely physical job, I am continuing this ...however other members might think something else could be better for you now...even the possibility of not recommending HGH at all
Dosing: start very low. This prevents sides like horrible fatigue, carpel tunnel, headaches or bloat. Sides keep you away from the gym too and usually when you have sides then your next thread will be asking.."what do I do?" and then everyone will tell you to lower your dose.
So...a good place to start is about 1.5 to 2 units a day...depending on script or not. Usually a script is less of a dose but not always the case....you never know.
2 units for awhile...maybe even the first few weeks...then gradually ramp up .5 at a time. Very gradually. Or you will have to back track and start all over. Setting your "sweet spot" is all personal. Some people stay around 3,4,5 units a day.
Please try to pin in the early AM as in: get up in the wee hours of the morning to pin and then go back to sleep for a couple of hours. This method also helps to blunt your cortisol which is desired. Separating the dose as in 2x's a day is fine but can be inconvenient for many. Either way, try to make sure to wait at least an hour on each side of injection...especially carbs. HGH and carbs do not really get along and this can mess with your glucose/insulin.
So...there you go!
