I like to start the first 4 weeks of a cycle real light and just feeling the muscle work and contracting. I will do absoluye perfect forn, then as I get stronger, my weights just go up while I'm still really contracting the muscle and feeling it work. I have recently been doing way more volume than im used to, think we did 26 sets just for shoulders, and i guess around that same number for everything else. All in the 10 to 12 rep range and always forced reps after the first set of each exercise. Also did side layerals yesterday to start off and got 200 reps in 4 sets doing reverse drop sets.

I personally do 2-3 day splits depending how I feel. I really feel that on compound lifts its great staying between 8-10 rep range three working sets after a warm up or two, but I actually feel better going high reps on auxiliaries or incorporating drop sets. Last 6 weeks of my cycles I usually do a bunch of super sets and high rep range. Do what feels better for you man.

First....Max out in size and wait til near 25 to cycle.

Second....don't go for MAX on your lifts. You should be repping above 8. Muscles grow faster than connective tissue and you'll tear. Drop sets....10x10.......mix in some high reps for pumps. Concentration lifts.

Alrite man...where to start with this one? Here's the thing, you're 21...you doin gear already? That's a lil' young. What's your BF%?...another important factor. If you're asking questions about some workout routines on cycle, then honestly you probably need to do some more research, mentally and physically, with yourself and finding what works for you without the use of AAS. Alot of times it comes down to trial and error...and sometimes that takes a couple years of fooling around with exercises and lifting techniques in the gym. I was finding what works for me and what gave me the best results for several years before hitting the gear, and that's the best way I can put it.

Workout routines, well...I usually seperate body parts on cycle. Something like this, just an example:
Mon. is Chest, tris
Tues. can be Legs
Wed. off
Thurs Back, bis
Fri. Shoulders, tris(I like crushing my tris 2x/wk.!!)
Weekends off, maybe some cardio if I feel like it.

Cardio is real important to muscle growth really. It increases mitochondria activity and increases your myoglobin content which is essential for muscle-building. Cardio also removes waste products from your muscle cells, like lactic acid buildup.

As for sets and reps...well, 8-12 reps is usually the sweet spot for muscle hypertrophy. Sets, usually on big lifts I do 2 warm-up sets followed by three work sets, so that = 5 sets for your big comopound lifts. Everything else I keep to 3-4 sets all depending on how much more of an isolation lift it is. Like I said, trial and error and listening to my body is how I figured out what works for me.
