BA 2% tops and BB 18% ish.
They dont make shit staril either, they stop the growth of bacteria, BA only actually.
IF the bacteria is in the bottle it wont grow, till you put it in your body, then it WILL GROW!
I have made my own brew for years, and about 3 weeks ago ended up with an infection, now it could have been the double alch swab that I did on my quad but let me tell you its not cool.
He is right as well, they use .45 in the lab, but a lab environment is not nearly the same as a personal environment.
Clean the shit out of your work space, spend the time and bucks on a .22
Clean and wash your vials if you buy them non sterile, get a baby bottle brush cleaner and take your time. If you rush your shit, its going to cost you pain.
Here is how I do mine:
Crush pellets with a mortar and pestle.
pre-heat oven to 350
Put oil in beaker in a pan of water, on 1-2 on an electric stove
place BA and BB and powder in oil, sir with glass rod (glass rod not required but nice to have)
Use a thermometer to monitor your solution. Dont go over 160F (not positive on this temp)
just let it sit in the heat and go wash your bottles, and stoppers.
Bottles and stoppers should be rinsed in an alch bath too, I put mine in a glass dish (90% alch and distilled water)
Use anti-bacterial soap in your sink wash up the bottles rinse in the alch bath, place on cookie sheet covered in tin foil, place in oven for 20 mins.
Place your stoppers on a clean paper towel.
Stir your solution on the stove.
Prepare your coffee filter in a NEW CLEAN beaker
Slowly filter your oil\ba\bb\pellet solution through the filter and into the beaker.
put new beaker of clean product back on the stove and bring back up to temp.
Bottles come out of oven
Use a syringe (I like the 5ml) and use your wattman filter .22 and filter up your product. A .22 should do about 100ml of clean product but with the tren pellet conversion it wont.
If your doing a large batch you can use a .45 500ml filter then a .22 filter.
I dont mind takin the extra time and steps to be clean and safe, I dont care if a filter costs me an extra 50 bucks.
THIS SHIT IS GOING IN MY BODY!
You can use a lot of these steps with any powder too.
Be safe!
