I usually don`t take ancillaries preemptively but when running tren I do. You can run .25mg - .5mg/ E3D and be good. I don`t exceed 1mg/week. If you don`t want to run preemptively you can wait to see if you get tren dick and then start the caber. Up to you. Hope that helps. Thanks for the question.

What is your tren dosage you may not need caber I can run deca with no caber at 300mg weekly if it`s your first tren cycle and your using 200mg per week presumably I doubt you will need it take p5p at 100 mg per day this helps naturally lower your prolactin hope this helps dont forget to vote 

If taking Tren Ace at 350mg per week or lower range. I pin ED and take p5p before bed each night this has always kept me personally from needing caber/prami. I always have it on hand in case but I`m not a fan of playing with things like my dopamine receptors if I don`t need to. If you have Tren Ace look up steroid plotter and put in tren ace, then look how unstable even ED injections are. I firmly believe everyone should pin ED when taking Tren Ace.

I usually keep my doses of tren and deca relatively low so i cannot speak to doses above 500mg but they are 2 of my favorite compounds and i have used each dozens of times (not together) and never needed caber, but i do always have some on hand JIC. Here`s the thing i`m not sure people really think about. Both progestin and prolactin, in both men and women, build breast tissue very slowly, especially compared to estrogen (look it up if you dont believe me). So sides from tren and deca from progesterone or prolactin will typically manifest as libido or erectile disfunction (deca dick) long before anything else. And if that rears its ugly head then a little cialis or viagra will generally do the trick (and i`m not sure it ever really has). I much prefer one of those 2 options to a compound like caber, that while is generally safe and effective, does alter brain chemistry and dopamine levels. Like i said, i always have some on hand but i have thrown out far more caber because it expired then i have ever used. Every drug has its own side effects and they all cost money. I dont use any ancillary unless i have to, but maybe thats just me.

I just do not use any ancillaries unless I need to. Unless you see and feel the side effects there`s no need to use any ancillary drug. They are not the default in any cycle, instead they are meant to be used only if needed. Regardless you need them at hand just in case. Good luck!

Even with 500 mg of tren per day i don`t need caber but wwe are all different so in case you get prolactin related side effects start with .25 teice weekly, in case the side effects don`t subside up the dose to .5 twice weekly. Good luck!
