I'll start by saying in no means am I a guru at any of this, so make sure to have a search of the forums and no doubt you will find some much better explanations of these products and the science behind them.
if you're looking to bulk, some supps to have a look at are:
PES Anabeta (or Anabeta Elite if your looking for more of a recomposition/leaner bulk)
D-Aspartic Acid (Purus Labs D-pol, USP Labs test powder)
Arachidonic Acid (Molecular Nutrition X-Factor)
Agmatine
Nutrient partitioning/ GDA products (Genomyx Slinsane,Southland Performance Slintensity, USP labs AP, Recompadrol)
PES Erase
Anabeta is a natural anabolic, great for muscle building and increasing appetite, with nutrition partitioning properties as well.
DAA will raise your natural test and assisting in muscle building.
ARA is a pro-inflammatory, many swear by it as a muscle builder although it can be harsh on the joints.
Agmatine is primarily used as a pump product but it also possess mode elevating and nutrition partitioning properties.
A dedicated nutrition partitioner will force nutrients into your muscle, preventing storage at fat among other benefits.
PES Erase complements anabeta and DAA well, reducing estrogen which reduces water, giving you a dryer look. It also reduces cortisol. can be harsh on your joints.
It is recommended to try products solo if it's your first time to help gauge their effectiveness and potential side effects. I would recommend anabeta first, followed by erase then DAA, as the anabeta/erase and DAA/Erase are both highly popular stacks, or you could run all three together. agmatine stacks well with anything really. ARA needs a few support supps to be run with it to take full advantage, so it's probably easier to try the others first.
on the topic of pre-workouts, there are far better options out there than no-explode. I can personally recommend PES Enhanced, insane focus and great pump, or Purus Labs Condense, which is also great for pumps and particularly vascularity. Other which I haven't personally tried but get a lot of recommendations are Genomyx origin and USP labs Jacked Micro, although Enhanced is probably the consensus best on these forums.
