DP does a great job of making smooth gear. They've been doing this forever and are sold by countless suppliers because they have such a long term solid reputation. As widespread as they are, you'd find endless posts on the net if they were some problematic lab, but you won't. Only the very occasional gripe from someone who doesn't feel something and insists the gear must be bunk, but you'll never find a bad third party test result. If anything, my only issue with them is their habit of overdosing their test a bit. I have my TRT calibrated to a certain. amount to avoid estrogen sides, and as soon as I switched from another brand to DP the sides started, so I had to dial back the dose slightly. Test is so cheap, no one goes through the trouble of faking it. The only bad test comes from tiny, sloppy labs making stupid errors. I'm much more confident in a Chinese pharma factory than bathtub gear. The little guys aren't making carefully crafted "boutique" steroids, they're doing what they can with limited, basic equipment, using the same raws sourced from China the big generic drug contracting factories are brewing with industrial level machinery. The difference is, when the tiny guys make some crap batch, it's much harder to find info about it because so few people are using it. There's safety in numbers.
