If I was to hypothetically use any sponsor here I would use EK or Z. Just thought you guys should know where to go. EK has some of the most potent prods on this forum if you can get them. I seriously think the DP prods are over dosed. Z is a close second on potency IMHO.
I may or may not have used HUGE amounts of both and I never had any sterility issues. No infections, no reactions just good clean gear from both. Z is probably a bit faster. Price wise EK can not be beat. So if I was a newbie at IM and had zero pull I would go with EK first. If I needed something faster then Z. No one has asked me to post this or paid me to post this. This is my honest opinion.
I have not used every sponsor so there may be better but I'm not aware of it at this time. Both guys have had some delays at times so speed may not be the best way to measure them.
Both Z and EK have some of the best reps around. If my hypothetical order was f'ed up I would PM ordawg1 or Irish. Both guys are true customer care specialists.
If I had sleep issues and needed something to relax me then I would go to WP.
I no longer rep for anyone and I'm on doctor supervised HRT legally.
