well mate its a bold move to use hgh as your first enhancer, how many iu's you thinking of ordering? IMO you would need to be on it for a very min of 16wks and if your using it solo maybe somewhere in the region of 6months to obtain some good results. Prob best to start with 4iu's / day, i used this before at this dose with 2iu's in morning and 2 before bed, 6days on / 1day off but there are many different opions on dosages / days on / timing etc. As for injecting if its jintropin then you will get a small flat stone in the pack used to score the water amp so its easier to break at the neck. I used a 2ml barrel with 1.25needle to draw the water and then inj into the hgh powder vial. Now slowly inject diluent into the HGH vial with the vial upright, insert the needle through the center of the HGH vial and angle the tip of the needle toward the vial wall. Tilt the vial slightly to allow diluent to run down the inside of the vial wall. Slowly push the plunger, releasing the diluent against the vial wall, allowing it to running down onto the HGH powder. Do not inject forcefully as the HGH will foam if agitated. Foam can stick to the inside of the vial, causing slight loss of HGH. For the same reason, do not shake the HGH vial during or after mixing. Now slowly and gently roll or rotate the HGH solution until it is all dissolved. If you have inj the full 1ml then with JIN it will be 1iu = 0.1ml, i would then use a slin pin for a sub q inj generally in the stomach area.... hope this helps in some way but personally i'd consider other routes, but if you got the cash then hey ho....
