This is a 6 week cycle:

Clen is taken 1 week on / one week off:

As in my experience it is more effective this way:

A mild anabolic of 50mg of Winstrol ED, Anavar at
40mg ED or Test Prop at 50mg ED or 100mg EOD is
recommended to preserve muscle lose and fight of
a catabolic state that T3 can cause. You could also
use longer ester testosterone , but they will take much
longer to kick in to be effective.

Start T3 at 50mcg as any lower makes no sense since
your body should be producing between 20mcg-25mcg
daily naturally... Clen doses use as a guideline along with
the T3 doses, everyone has different tolerances for both,
but this is was very effective for me...

You can use a simple ECA stack during your off weeks in the
place of Clen if you want to help with the fat burning progress...
Your diet should be fairly high in protein, moderate carbs with
no sugars and moderate fat intake... You may also want to add
a source of EFA's like a flax seen oil to your diet during this time...
Also Clen is known to cause alot of muscle cramping... Also I start
off week three at the same dose I finished with at the end of week
one... Again all depends on your tolerance to the drug; you may
want to start a little lower for a few days before going right back
to your maximum dose.

Drink more water along with taking extra minerals and potassium
and 2-3 grams ED of the amino acid L-Taurine is recommended if
cramping is really a problem... Also take your Clen and T3 in two
divided doses during the day... Also to give you an idea my daily
calorie intake was probably about 1,000 to 1,200 lower then normal
for this entire time...

BTW when I ran this cycle I was running 900mg week of Test Cyp
as my only anabolic right at the end of a bulking cycle... My results
is I went from a chunky, but thick as a bull 240lbs to a fairly hard 212lbs
or so in only 6 weeks... Again adjust the doses to fit your tolerance...
At these doses you will be sweating and hot all day long... Plan on
losing some muscle mass even with the anabolics...

Clenbuterol Cycle

Based on its rate of elimination from the body, and how much is usually needed to be effective for athletes, my recommendations are the same for both men and women. Youll need to take 20mcgs upon rising, and then repeat that same dose again later in the day, and then once again in that day (if you find you can tolerate the effects). So youll start with 20mcgs, and then repeat that dose 2 more times that same day if you can tolerate it (side effects will determine this hand shaking, sweating, etc& classic stimulant sides). Then you can start increasing the dose gradually. Personally, I wouldnt work my way up to more than 200mcg/day. 60-120mcg/day is an average dose. And keep your Blood Pressure at (or under) 140/90, while on clen, just to be safe. If you go over that, lower the dose. Youll also want to know your body temperature, upon rising, for the week before you start taking your clen, and then monitor it (again, as soon as you wake up) throughout your Clenbuterol regimen. When it returns to the level Clenbuterol was at before you began taking the clen, youll need to start taking your Benadryl or Ketotifen, as the decrease in Body Temperature back to original levels indicates the thermogenic effect is beginning to decline.

Clenbuterol can also cause a downregulation in testicular androgen receptors and in pulmonary, cardiac and central nervous system beta-adrenergic receptors(6.) possibly making steroids less effective (if there is androgen receptor downregulation elsewhere as well, then its highly probable) while you are on clen; but definitely making clen less effective as time goes on and you keep taking Clenbuterol . To counteract this, you can take some ketotifen every 3rd or 4th week that you remain on clen. Its a prescription anti-histimines, so itll make you drowsy (take before bedtime). Basically, the way this works is to reduce beta-2 receptor activity, and restore receptor function (15).

Another option, if you are worried about receptor downgrade, is taking Benadryl, at around 50-100mgs/night before bed (every 3rd week or so, for that week). Benadryl is sold as an anti-histamine in the United States, and/or a sleep aid elsewhere in the world. However, Beta receptors are embedded in the cells outer phospholipid membrane. The stability of the membrane has a lot to do with the proper function of the receptors. Methylation of the phospholipids is stimulated by the binding of beta agonists to their receptors. Methylated phospholipids are foreign to the body, and when the body recognizes them as foreign, it breaks them down with phospholipase A2. This changes the structure of the outer membrane which results in desensitization of the beta receptors. On the other hand, agents that inhibit phospholipase A2 slow desensitization.

Cationic ampiphylic drugs are known for their ability to inhibit phospholipase A2. Benadryl (diphenhydramine) is a cationic ampiphylic drug.

Ergo, Benadryl slows desensitization of Beta receptors (i.e. Upgrades them) by inhibiting phospholipase A2, which is the enzyme that breaks down methylated phospholipids, and this action in turn keeps the phospholipid membrane stable, and thus keeps the receptors functioning properly. (7). This will allow you to use clen for much longer and itll still have the same effects. Also, since Benadryl is an anti-histamine, and histamines have a direct effect on beta-adrenoreceptors (not just Beta-2s but all of them), using an anti-histamine will have a direct effect on reducing beta-receptor stimulation (16), and thus upregulating your beta-receptors.

hope it helps.
