Ok,you want to run tren on your second cycle,gonna let that slide.
But there is absolutely no reason to take Boldenone and D-Bol:
1.Tren itself always crushes lipids and increases hematocrit and BP(in most cases) and boldenone is just going to make it way worse with practically no additional benefits because the dose it pretty low(going to get dwarfed by tren) AND the fact that Bold is a long acting compound(undec.)that will take at least 6 weeks to saturate(by that time tren will be fully active).
2. Same goes for D-Bol.You don't need a kickstart if you have tren,not because it's quick acting,but because both compounds are harsh.And keep in mind,your cycle is 16 weeks!That means you expose your body to a huge amount of stress even without bold and D-Bol(starting from week 4+ when tren and test finally kick in).Why would you use D-Bol that is going to destroy your cardiovascular system,liver etc. even before tren kicks in just to "start your cycle" a few week earlier?
A better approach is simple:
1. 400 test E(the dose that is going to give you more growth without a ton of water retention or serious BP issues like with 500mg+)
2. 300 tren A(typically a sweet spot for gains without massive sides.Use it only if you understand the risks of taking this compound).
Tren Ace is superior for a first time tren user because if the sides get unbearable you can quickly get it out of your system due to the short ester(or adjust the dose).
Do not use anastrozole aggressively without a bloodwork and absolutely do not use cabergoline before you get your prolactin test results
1.Cabergoline can crash your prolactin easily(prolactin levels with 19-nor compounds are highly individual and much more unpredictable than estradiol levels.For someone 300 tren can cause no progestin sides,for others-elevate their prolactin levels to the sky,so you should get an early prolactin test).
2.Tren A will kick in really fast,that's another reason to drop D-Bol AND check your prolactin early)).
And for supplements I can suggest:
1.NAC(potent antioxidant)
2.TUDCA(liver support)
3.High dose fish oil(cardiovascular and neurologic support)
4.P-5-p(neuroprotection and mild prolactin control)
5.Melatonin(tren will likely disrupt sleep)
6.Coenzyme q10
and do your research on other supplements if there is some side effect that you'd like to reduce.
Make a good training plan and stick to it.This is going to yield you 80%+ of your gains.
Nothing to say about PCT and hCG usage.You will need a very strong pct after finishing this cycle(do your research on how to plan a PCT).
Bloodwork:
Step 1:pre cycle
Step 2:early prolactin test
Step 3:mid cycle
Step 4:end of the cycle
Step 5:8 weeks after finishing your PCT to ensure testosterone restoration.
(all bloodwork steps are not negotiable)
Determination , discipline and a smart approach will give you more than PEDs alone!
Good luck!
