There is little or no need to stack secondary drugs with fina. It does not aromatize. There is some concern as to fina being progestagenic, so you should you opt to stack it with an aromatizable compound it may worsen potential gynocomastia so adding winstrol or Nolvadex, or even both to such a stack may be wise. But in itself or in a non-aromatizing stack this is not necessary. The use for post-cycle estrogen antagonists is limited as well, so Nolva or clomid to boost natural test will have little use. It is a very strong androgen receptor agonist however, so perhaps using some HCG after a cycle may help you retain more gains and prevent testicular shrinkage, but since HCG does increase estrogen that does reinstate the use of Nolvadex or clomid as well.
As of now the main source of trenbolone is from implants for cattle being converted into an injectable or transdermal compound, from powder, and of course Underground Labs. "Home brewing" powder or cattle implants seems to be the preferred method of obtaining injectable trenbolone acetate, because the user would have much more control over the potency and sterility of the drug. Trenbolone is much more expensive than other anabolic steroids ranging from 15 dollars per gram of powder or 150 for a single 10 ml bottle. The cost of trenbolone should not matter, it is worth every penny.
For bulking up, there may be no better steroid than Trenbolone Acetate also called Finaplix. Its anabolic effect is five times that of testosterone and it doesn’t convert to estrogen, which makes it free from side effects like gynocomastia, water-retention, etc. Finaplix is not without its fair share of side effects, however. Testicular atrophy, hair loss, enlarged prostate and acne have been reported from using this drug. Finaplix will also shut down the body’s natural testosterone production, which can lead to sexual dysfunction. Finaplix has a short-lived ester which means that it must be inject almost daily to maintain steady results. The good news for this is that the drug can be immediately stopped and the body can heal if adverse side effects appear.
