You said that you experience DOMS for 2 weeks after lifting? Thats insane. Sounds like you train very infrequently, ie sedentary for a month and then decide to bang out 6 sets of 90% max a2g squats. Solution= train more consistently. Or get checked for polio, because 2 weeks isnt normal.
Id say 10 lbs is doable in 2 weeks, crash style. Just be prepared for a fat rebound afterwards. Count calories and eat 1000 below maintenance while training almost everyday. Any anabolic will do, just to hang onto lbm; but tren does have that added lipolytic/diuretic effect, which is helpful.
eca w/green tea will assist. If you have the cardiac strength of a clydesdale and the stim tolerance of richard pryor circa 1980, then otc propylhexedrine may be a useful tool for your extended fasting. You wont eat on it. Or sleep. You may start hearing colors after a 4 day binge. Tactile hallucinations are likely and you should carry a firearm at all times.
