The thing with Powerfull and natural anabolics are just raising test gradually, ex: SHGB binders like activate use your own test to have more available until a plateau is reached, then gets down gradually.
The synthetic ones are REPLACING your own test, and your body gradually stops producing some. But with the natural ones, you make it higher in a natural way, you dont inject the real hormone, but you find a way to tell your body to have more. All are different. I would say:
Activate: you have the same test levels, just more available
Powerfull: Tell your body to do more, afterwards, it just decreases slowly until normal
Symmetry: Don't know at all if it raises test, but I am trying soon, will do a log on it. I am sensitive, so oily skin could be a sign of high test.
Aromatase inhibitors(6-oxo, reloaded, novedex,...) are simply killing or masking oestrogen so your body wants to compensate and make more test to make up. Just like when you use steroids, oestrogen is higher, but who cares, on cycle test is blasting through the roof.
So this is my opinion, maybe wrong on certain points, but use it as you wish
