I gave it a shot a while back had to stop due to pip. 1st injection was 100mg in glute ran under hot water prior to injection. Went in smooth, no issue during the injection or next day for that matter but on the 2nd day the pip was intense and lasted for 2-3 days. 2nd injection was 50mg mixed with 125 mg Test - C, ran under hot water first again, injection was no issue, and used a massage gun at/around injection site afterwards. PIP was much less severe on 2nd shot but still slightly noticeable but definitely manageable. Decided to discontinue the DHB as I didn't see where the juice was worth the squeeze at that time. Might revisit the idea of adding DHB somewhere down the road but it was a no go for the time being. If going to use, smaller does mixed with test is definitely the way to go, for anyone wanting to give it a try.
