I got this from Mr. H's website:
Finaplix-H (the H is for heifer) is a cattle implant that comes packaged in a cartridge containing 10 dosages of 10 pellets each (100 pellets total). Each pellet contains 20 mg of trenbolone acetate for a total of 2 grams of TA per cartridge. Component-TH is the same as Finaplix except it contains twice the amount of dosages. So instead of getting 2,000 mg of trenbolone, you are getting 4,000 mg.
