OK guys, this went very smoothly and with no problem what so ever. First you will need an empty bottle(like an old T-gel bottle with a cap and an extra cap for the Penetrate bottle.)
Take the Penetrate bottle and shake very well(as the oil substances will have settled to the bottom.) Now remove the cap from the Penetrate bottle and the empty bottle. Pour half of the Penetrate into the empty bottle and cap so you don't spill it. Weigh out 3 grams of 4ad. Take the Penetrate and put the cap on but leave loose. Put it in the microwave for 10-12 seconds. Take a large mouth funnel and put into the Penetrate bottle and pour the 3 grams of 4ad into it. Cap the bottle and shake for approximately 1 minute. It should be fully dissolved with no clumps or particles. Weigh out 3 more grams of 4ad and pour into bottle and repeat shaking. Again weigh 3 grams of 4ad and funnel into your Penetrate and shake. It should hold this 9 grams before adding the remaining half bottle. Now take the bottle that contains the remaining half of Penetrate and heat in the microwave for 10-12 seconds. Pour the remaining 3 grams of 4ad into your Penetrate that you have already mixed and then add the remaining half bottle of Penetrate and cap your Penetrate bottle and shake. Mine held all 12 grams without a problem. I got 9 in a half bottle easily so I could have got 18 grams in a bottle and some that said it would hold 20 grams are probably not wrong. The combo of the gentle heat and marble did the trick. If you do it this way, you should not have any problems. Good luck!!
