First, thank you for making the breakdown easy. I'm assuming BB benzyl benzoate? Is BA Benzyl alcohol? GSO is grape seed oil. Med lab supplies carries filtered grapeseed oil. Is this g2g? Final question. Do I use the syringe filter to draw the finished oil out of the beaker and then add 20ml per vial. They have Whatman GD/X 25mm sterile PVDF syringe filters. From the pick it looks like it just goes between your syringe and needle. It looks like the largest syringe med labs sells is 60ml (Monoject 60ml Toomey tip). This would be perfect for the 3 20ml vials?
Yes BB= Benzyl Benzoate and BA=Benzyl Alcohol and GSO=Grape Seed Oil. You can just buy GSO from your local grocery store. I don't think there is any difference between the filtered stuff and regular stuff other than medlab has already filtered it once for you. It may be a little cleaner but for the price I don't think it's much better than what you get at a grocery store.
So using the formula I have outlined what I would do below. It may sound complicated but it's really easy once you do it a couple times. Once you draw up your mixed product into the syringe you put the filter on the end with a needle on the end into a sterilized vial with another small guage needle sticking out to equalize the air pressure. I would advise against buying the 60mL syringes as they are a bitch to push oil through. I would go with 10mL syringes as you get more pressure on it and your only trying to push 60mL through it . Basically you would push 10mL through it then disconnect the filter draw up another 10mL connect the filter again and start pushing. That's going to be easier than trying to push 60mL all drawn up.
Making your product-
1. Measure out 1.2mL BA and 12mL BB into a beaker (you can use a glass bowl if you don't have a beaker.
2. Add 9g of Primo Enanthate.
3. Mix as best you can.
4. Measure out 38.31mL of GSO and put into your beaker.
5. You can heat this up a little by various means but honestly putting it in the microwave for 15-20 seconds is fine. With a little heat this should all mix into a fairly clear solution.
6. Draw up 10mL into your sryinge the attach sryinge filter with 18g needle on the outlet of it.
7. Take a pre-sterilized vial and put a smaller 27g needle through it at the edge of the stopper so that as your pushing solution into it that needle allows air to escape it.
8. Take your 10mL syringe with solution, filter and needle attached into the the pre-sterilized vial and apply pressure. It may take 5 minutes or more to get it all through the filter.
9. Repeat as necessary until all your solution is filtered.
