I also find IM reduces this compared to sub. If I take 20 iu at once I pin 4 or so places same pin im- maybe each delt 5 then inner quad 5 each. I used to worry cts or lack of legitimized products. Either my tunnel expanded over prolonged use, I am used to symptoms, or after 20-40 Ed I just acclimated. I am referring to gtg sponsor products with good bloods to show. I am really liking thanktropin at the moment. Very Similar to elitropin- in effects and clean. Tail end of 1000 iu run with the reds and next is 2000 Eli at 20-40iu day. Southern states in about 16 weeks. I'll come in 30 lbs heavier and leaner than when I won overall NPC State show couple years back. Then I was maxing at 8/day which I thought was high. But now I vastly lower the aas and quadrupled the hgh. Different look. More mature muscle with striations. I barely need to diet as bf barely reaches double digits while bulking- on half the aas.
