in my first experience with juice I threw 6 grams tren in each bottle and did 15-20 sprays 2x a day. This would provide the same amount per day at putting 2 grams and following the normal androsol spray protocol (60-100 sprays). I did this because Bill Roberts told me that diluting the tren too much would mess up the time-released absorbtion into the skin. I doubt this is the case though...for the last bottle I threw 2g in and sprayed 70x 2x a day and got the same results.
really it is alot cheaper and less of a hassle to convert and inject the stuff. Spray delivery works, but I don't think it is worth it.
