i heard about this, but thought it wasn't so many people. i've only used DAA once during PCT and it was with clomid and erase pro. I'll read up more on DAA by the time my cycle is over. Everything is on-hand so i can always decide not to use something or add something if needed.
using DAA on PCT is not a wise move IMO. I'm not a fan of DAA in general, due to its ability to increase estrogen as much as it increases testosterone in most end users.
One thing I found I liked both during on cycle as well as pct was a 3,4divanilly based product like Testabolan
On cycle: The 3,4 divanilly has a high affinity for SHBG(sex hormone binding globulin) and ABP(androgen binding protein). SHBG and ABP would normally reduce your cycles strength by binding to an inactivating the hormonal compounds being used(in this instance 1/4 andro + epiandro). By using this on cycle, more of you SHBG and ABP would be bound to the 3,4divanil, leaving more active hormone in your blood(thus increasing the effectiveness of the dose taken)
Off cycle: All the benefits as when taken on cycle, but in this instance it allows for your testosterone to have a bigger impact in your body. When you're on PCT and your test levels aren't at 100% you need to make sure the testosterone you DO have contains the highest level of free testosterone possible, so you don't have unwanted side effects. Helps libido, and free test levels bounce right up in PCT
