I only used their dbol for about three weeks (because I'd already been using another source's for two weeks prior to that), and I had to lower the dose a bit after only a little over a week because my blood pressure was just through the roof. Not sure what other information I can really impart on you...I mean, yeah, it's dianabol.
As for the test prop, it's awesome. For some reason, it's always of a thinner consistency than MLG's tren ace. Tren requires significant pressure on the plunger (I had to buy a pack of 20g needles just to extract the tren without having to wait 5 minutes) but the prop slides very easily through even a 25g needle. I've never experienced PIP with any of MLG's injectables, and from what I've seen this doesn't seem to be a prevalent complaint.
Hope that helped, good luck finding what you need.
