DAA is proven to be a very effective testosterone booster. It is generally recoomended as part of PCT after any cycle. It's cheap, easy to take, effective; what else do you need?
As for the NoXplod and Jack3ed, dump them both. Neither is a very good as an "N.O." booster. You get the rush of energy from the heavy stim dose they both have. if you're looking for a solid plasma volumizer/NO booster, take a look at Hemavol from iForce. An absolutly great product, fairly priced, and I've never had better pumps than with Hemavol. I recco the powder, because it's easier to take than 10 pills. Plus it tastes like Lemonheads candy, not too sweet or tart, dissolves easy, and works better than most products in the same class...
And I'm just curious, you say you're new to supplements, but not to X-Tren or other PHs? I don't think you need to take PHs. I'd guess you're not at your natural peak, and just don't have a good diet or plan in place, no matter what you think. I could be wrong, but to not know basic supplementation, and then be asking PH questions.. Not advised IMO...but I'll help you where I can..
