Hoping someone can tell me what is happening with my hcg injections. I just pinned my HCG for the third time and so far every pin has been extremely painful. The pin goes in without much pain but as soon as i start pushing the plunger in it causes an extreme burning/stinging sensation. So far my Test-E injections have gone pretty well but i dread the HCG because it is SO painful. Is this normal? If not what could be the cause and how do I fix this. I am mixing 5000IU with 5ml bac water, and i am injecting 250IU/.25ml per injection. Thanks in advance for any advice
