No real need for ‘sterile’ oil…
Go to heath food store and select your choice of organic, cold-pressed (or expeller pressed) oil.
I use soy, but you can use grapeseed, cottonseed, or whatever else you want.
If you absolutely insist, when you get home you can put 4 or 5 oz in a little pan and bake at 250 for 90 minutes…this is the temperature and pressure used in home canning that kills not only all bacteria, but all spores as well.
After it cools, put through a .22 Whatman into a sterile vial.
I guess at this point you could cook it again, but if you do, you need to be checked for OCD.
I’m not really sure what to tell you about filtering test…I thought it was pretty obvious…but anyway:
Take a sterile vial. Take one needle (doesn’t really matter to much what size…23 would be pretty good) and put it in the top as a vent…put another one in the top as a filler. Take a 3mml or 5ml barrel full of ‘product’…put the Whatman on the end…attach that assembly to the 'filler needle and press into the sterile vial…repeat until product is gone/vial is full…works better if ‘product’ is heated to about the temperature of hot chocolate…discard ‘vent’ and ‘filler’ needles…LABEL THE VIAL
Now as far as diluting the test. You could have mixed the proper proportions in a small container and combined the two steps above…OR…I usually keep them seperate and mix in the syringe prior to dosing. Just draw the proper dose into the syringe and ten draw in enough sterile oil to reach the approx concentration…for example…if you have some 250mg/ml test hat is really painful and want to take a 125 mg dose…draw 1/2 ml test and then top off with 1/2 ml oil…the amt of oil you add is relatively unimportant a long as you get the hormone dose right.
Hope this helps
