i ordered Dianbal 50 from gbn. the one i ordered were from balkon pharm, but they were out of stock so gbn asked me if i would like any other brand and they would give me the same amount. i have been curious about kalpa pharmacy so thats who i went with. i originally ordered 60 so i got 3 packs of 20 from kalpa. these have to be so of the best d bal out rite now. or the strongest. the first day i forgot to split it in 3 and took a whole 50. 15 min later while working out i was pouring sweat. im glad to have got these instead of the balkon. i just ordered a few bottles of the sust 350 kp from gbn store. i cant wait to try. the most i had ever done was 325 mg by axio labs and that was the best sust i have ever done. i will be posting how it works soon as i start. gen-shi sust 250 is another good one. gbn gave me 30 tabs of sildenafil citrate [free] and they are great. 50mg and i only needed half. wow! those guys at gbn have there stuff together.
