I've been doing business with GBN and HT for a while now and have never been disappointed! Gbn is the only place to do business with . 100 percent quality and great prices . My workout partner is on trt but he doesn't use what he gets from pharmacy, he uses Kalpa. When he started his blood work showed his test level was 180 ng which is extremely low and 6 weeks later it was 1,500 ng after 1 c a week of Kalpa C ! I'm going to get paperwork from lab and post it also . If there's ever a problem like a broke vial when ur order arrives , HT will re send that vial and make it right . In the past I've ordered from other places and none of them compares to GBN. GBN has the best customer service, best quality and best deals ! Thanks Huge Tom!
