How I administer Clenbuterol:
I do 12 days on and 12 days off. Some people do a full two weeks on and two weeks off, but I feel that after about 12 days the receptors are done, and taking more clen is pointless. It takes about 12-14 days after your last dose for them to recover enough to start administering clen again.
I use an ephedrine caffeine stack during the time I am not on clen. You can take them together if you really want to, ephedrine targets differant receptors than clenbuterol, but I don't like to do this because my heartrate is allready high enough from the clen.
Here's the stack.
Day 1 - 40mcg
Day 2 - 60mcg
Day 3 - 60mcg
Day 4 - 80mcg
Day 5 - 80mcg
Day 6/12 - 100mcg (from here out its up to you) From here you can go up another 20mcg ed untill you get the shakes, once this happens drop the dosage by 20mcg and BANG thats your tolerance level for clen.
Day 13 start taking an ECA stack (whatever dosage you are comfortable with)
Once the 12-14 days are over, you start back taking the clenbuterol for another 12 days, you cycle up a little differant this time....
Day 1 - 40mcg
Day 2 - 60mcg
Day 3 - 80mcg
Day 4 - 100mcg
Day 5 - (again from here out its up to you)
I very rarely go over 120mcg ED but some people are less sensative. I monitor my pulse. If I take my entire dose in the morning, I check my heartrate about an hour and a half later, and make sure I don't have the shakes. My resting heartrate is around 75 bpm, so If Two hours after taking my dose my resting heartrate is around 105-110 bpm, I don't need to take anymore.
WRT Liquid, It's pretty much the same as the tabs, you just need to know what the microgram per ML ratio is, and administer it the same. Clen survives the digestive tract very well, so there isn't a real differance between liquid or tabs.
