The dose of clenbuterol is about 20mcg per day, and some people will need 40mcg. Sometimes people take more, but generally in short term. When used to enhance athletic performance, the amount of clenbuterol is generally from low to high, increasing to a level above the beta-2 receptor stimulated. It’s ideal to start with a daily dose of 40mcg. When the body gradually adapt to this dose, can take more to increase fat loss.
Usually there are three ways which are effective, but you need to try to find the one that works best for you.
 cycle of two weeks
This is mostly used, use clenbuterol for two weeks ,then stop 2 weeks, and then take clenbuterol again for 2 weeks. Users gradually increase doses from 20mcg to the maximum dose per day. Use the maximum dose in the last few days of the two week, and then completely stop it in the next two weeks. Two weeks after the start of a new cycle of use. Two week cycle is very effective, but also has its problems. The body in the disabled two weeks will surely reduce the efficiency . this is not means that you will gain fat, you will reduce fat as long as keeping up your diet and training ,but will be slower.
 Continued use
Because the body will gradually adapt to this stimulant, the continued use is largely difficult to operate. But believe me, this is a very effective plan, because clenbuterol can improve metabolic efficiency within five weeks. Users may use 20-40mcg daily dose within the first 2-3 weeks. 2-3 weeks to increase the daily dose of 20mcg and maintain 2-3 weeks. Keep this dose until end. This plan will keep your body’s metabolic rate at a high level, although it will not be able to experience sudden progress, but it is really effective
 The middle way.
In fact, this usage is to combine the two ways mentioned above. Usually 4-6 weeks before the game will have a good effect. Users from the 40mcg daily dose gradually increased until the maximum dose, in the last 7-14 days to maintain the maximum dose. After that, if you still need to use it, you’ll need to wait another 4-6 weeks. So this plan is more suitable for short-term users.
Whether you use what kind of plan, use the highest dose of clenbuterol is generally not more than 120mcg every day, some men feel that 140mcg has a better effect, but more than the amount of 140mcg ,or it may cause serious heart problems. At the same time, A cycle should not be more than 16 weeks among a year.
