I purchased TestoBlend350 and just started injecting just .5 ml twice a week to test it out. Poked upper right glute. Seemed to be okay until next day. Had an egg sized lump and hurt like hell. Well, I thought maybe it just went in wrong. So, I tried upper left glute 4days later and immediately after injection got egg sized lump. Took weeks to go away, actually still feeling it now. Ive have never had such reactions to PEDs. I am not a complainer and even contacted the DragonPharma site to ask what preservative and/or base oil was used (there is no description on bottle or site), maybe Im allergic to something. They told me to see a Dr. and contact person who sold it to me;which is impossible. They know there is no way to contact sellers. I am dissapointed and pissed. Kind of strange how there are no negative reviews. Curious to see if this makes it.
