Was taking gh in my stomach for months and then switched to intramuscular shoulder and it definately became more noticable.. only use slin pins 12.7mm length but pressed in a bit further.. and there is more blood flow there compared to abdomen area so I assume for uptake or quicker.
try 6-8iu/day for 10 days 2-3 shots per day.. in my opinion if you dont get cts yours are no good.
Every single good quality gh Ive' taken causes cts within 2 weeks even below 5iu/day.. where ever gh that doesn't work at all or work very good NEVER causes cts at all.
I guess the intensity of the cts can be related to diet (sodium) and water retention in general but I've had gh that causes zero water retention or actually seems to reduce the water from my body alltogether, and it still gave me bad cts and that was only 3.33iu/day split into 3 shots.
serono saizen, jintropin from over 10 years ago when it was always real, and a generic green top, and now rips.. all cause this even at 3-4iu/day
