Who would have guessed this one. A solid report come through on Betancourt’s concentrate. Makers of novelty items and not so much protein powder. D-Stunner is well worth the dollar. Looking at a price similar to Neurocore and Jack3d. The product does not take ingredients from all the other big names. Sticking with a DMAA base this pre-workout packs in, beta alanine, carnitine, theobromine, phenylethylamine, usual creatine additive and a surprise appearance named cyanotis vaga, root. Little strange on the contents but this little supplement makes for one hell of a hit. No need to go long here. Use others, expect the pump of Neurocore, the strength and muscle drive of Jack3d. Worst taste between everything but well worth the results. The one downer worth naming is the rest periods between sets, not as powerful as Assault. Endurance is something that it brings too. No dying out after that 30 minute mark push to 60. The last loss to mention, no mental focus or aggression like Nitraflex. A mix of everything. More to the point, a mix that is not available in any other supplement. Small company but one huge rep for this 290g tub. Approved!
