Isopropyl alcohol can be used- it is the carrier that most topical pro- hormones use.
DMSO- can be used with very good effect- you will probably get GREATER uptake with DMSO
better than isopropyl alone is Isopropyl or ethanol (this is actually better from a health standpoint) mixed with isopropyl myristate which will give greater uptake and longer release- this is the formulation used in androgel. This is a greasy combination and can be annoying.
with DMSO you will get a greater uptake but it will peak rather quickly- some people prefer this as it MAY decrease suppression of the HPTA.
I have not looked into increasing uptake thoroughly... maybe in an upcoming article-- though I am not a fan of TREN as it is a progestin.
DOSAGE: this seems to be an area of contention. WITH VERY GOOD REASON... transdermal uptake will vary considerably due to a variety of factors.
couple of hints to maximize uptake-
1. exfoliate daily
2. clean application site with alcohol
3. use areas where vascularity is apparent and skin is thinnest.
peace
btw- scotsman is pretty familiar with transdermal fina and his brother, insane as it may sound, is the only person I know that has taken PGF2A in his traps
