thanks for info, I'v been using 23g needles 1', tried 25 with oil heated and it won't go through. it's icn test depo, there oil seems to be much thicker than others. wanted to try test base in water, can it be made like Winstrol (winny) with the peg80 and peg400, or do I need to add anything else? thanks
also is npp esterless, I thought it was?
