Well there are several popular dosing protocols with Clen. It boils down to maybe trying them and finding out which one works/feels comfortable for you. Clen differs in dosage and effects from each individual. Some people claim that they are completely immune to the effects of Clen and it does not help them at all, although I have never seen any scientific reasoning behind it. However enough people have said it for there to be some truth in it. The most important thing to remember when using Clen is that the body quickly becomes tolerant to it. Clen down regulates beta 2 receptors in the body and eventually (usually in the second or third week) results have slowed to a stop. For this reason Clen has a variety of dosage protocols designed to prevent this down regulation.
Firstly we need to start at a low dose and slowly build up to a dose that is effective but not uncomfortable. I would recommend starting at 40mcg. Stay at that dosage for three days then up the dose by 20mcg. Repeat this process until you reach a dosage where you can really feel the Clen working (slight shakes, slightly faster HR). You may want to take your body temp daily while doing this. An effective dose will raise the body temp by about 1/2 a degree. You can also monitor when it becomes ineffective as temp will drop back to normal. My Clen dosage looks some thing like this when I'm starting:
Day 1 60mcg
Day 2 60mcg
Day 3 60mcg
Day 4 80mcg
Day 5 80mcg
Day 6 80mcg
Day 7 100mcg
Day 8 100mcg
Day 9 100mcg
Day 10 120mcg
Day 11 120mcg
Day 12 120mcg
Day 13 120mcg
Day 14 120mcg
I normally stop at 120mcg as this dosage works for me with minimal sides. Also taking 5gm of Taurine everyday to keep cramps away as Clen depletes the body of this.
I take all my Clen in the AM before cardio. Many don't like to take it all at once and split the dosage throughout the day. I find that if I do this the last dose affects my sleep and I feel a bit "wired" in the morning!
A popular method is some people will stop using Clen at day 14. They will then take 14 days off to allow the beta 2 receptors to up regulate. They can then recommence and the Clen will be effective again for a further 14 days.
More recently it has become fashionable to use an antihistamine compound to up regulate the beta receptors while remaining on Clen. This is my preferred method. There are two ways I know of doing this.
1. Use zaditen/ketoifen taken at 2-3mg per day along with the Clen. Users report staying on for 12 weeks plus and the Clen is still effective. The downside is that many people get very drowsy using these compounds and are unable to train properly.
2. Take 50mg of Benadryl or another antihistamine containing 50mg of diphenhydrmine (Sleep Ease from Boots Chemist if you are in UK!) every night during every third week while you are on Clen. So I would dose my Clen as usual and at day 14 I would add the Benadryl every night for 7 nights during every 3rd week(while still taking the Clen). Discontinue the Benadryl when the 3rd week is over as the Benadryl has upregulated my beta 2 receptors and repeat. I favor this method as it helps me sleep and does not affect my performance in the day.
Q. How do I come off?
A. I normally lower the dose slowly day by day until I am off as I don’t like to suddenly shock the body, however there is no evidence to say it is detrimental to come straight off it is just my personal choice.
