fina contains tren acetate -- the anabolic substance your talking about
you inject feed cattle 60or so days before slaughter in the ear with a special gun -- and you(or your hefer) will GROW
Winstrol is probably the perennial veterinary steroid. Unfortunately, its off the market and is only available through compounding pharmacies legally. I've prescribed this drug for use in ferrets, rabbits, horses, dogs, and cats with severe kidney and other wasting (such as protein losing enteropathies or FIV) diseases. It works very well for helping them maintain muscle. This is a DEA schedule drug.
Equipoise (boldenone undecylenate) is a horse drug. I've prescribed it for horses, ferrets, and rabbits. This is also a DEA schedule drug. Both Winstrol and Equipoise are banned for most performance events and are heavily tested for in the horse industry.
Trenbolone is in implants (Synovex, Component, and Revalor) desigend to be implanted in the backside of the ear of feedlot and finishing cattle--typically the last 60-80 days prior to slaughter. The thing abotu Trenbolone is that it is getting harder and harder to find without "other" ingredients such as estrodiol (sometimes up to 20 or more MG/dose of pellets) or antibiotics such as Tylan (tylosin).
The side effects of tylan always make me smile when I think of the bodybuilder who screws up when they are trying to home-brew trenbolone and they get the wrong implant---the one with Trenbolone and Tylan.
Side effects include:
Adverse Effects: pain and local reactions after IM injection, GI upset (anorexia, and diarrhea). May cause severe diarrheas if administered PO to ruminants or by any route to horses. Swine: edema of rectal mucosa and mild anal protrusion with pruritus, erythema, and diarrhea
There is not a human approved Tylan product because of potential side effects.
