i am only in my first week, i have been cruising on test e for awhile now dieting down, so early days for me too, i have also had to change labs which has made me too also very nervous about junk gear . so in the same boat as you at the moment.
my experiences with tren started with tren acetate , where i would notice the shorter temper after the first week. my experience previously with tren e though i would say round week 3 i would notice i became more irritable etc.with week 4-5 i would start to notice the strength gains and alot more focus and aggression in the gym
ironic but possibly a good sign is you being anxious as its also a sign for me, as well as i am slightly warmer especially at night while sleeping
sustanon and tren dont inspire massive water bloat so 4lbs isnt bad going so far imho
the sides i found come on gradually with me and tren e , more aggressive with tren ace , but overall i experience worse sides in the long run with tren e with regards feeling tense etc.
weight wise will be difficult to tell for the next 4 weeks, as i am using this time to strip some more bodyfat while waiting for the compounds to be in full swing before switching to a lean bulk , so my calories are restricted and carbs low , and plenty cardio at the moment
i cant help you with the acne, as i dont suffer that side effect , usually a good sign ?
