I have attempted to use 1-T Tren twice, with no success. The compound, and it's cousins do not agree with me for whatever reason. It may work fantastic for you though. Some people really dig it. I do think for an experienced user, it may be best to stack a derm with a methyl, or phera plex. Trauma1 has a log on 1-T/Phera I believe. Others have used epi w/ 1-T, etc. IMO, for the price, not worth it. Derms can be very effective though.
