If you believe you are ready for one of the following cycles you will have many cycles under your belt, supplemented with numerous anabolic steroids , 5 is a good number and have learned how to not only have successful cycles but ones in-which side-effects are controlled. Further, to be ready for an advanced cycle you will be one who is able to maintain more gains after a cycle than you lose. Some gains will always be lost after a cycle is complete, this is a given but maintaining a majority of your gains is possible. If this is not possible for you then you need to reexamine your use, your diet and perhaps even your training.
These are the guidelines but there are few things you need to understand. If you have fulfilled the first three and are satisfied with the results you do not have to move to the next level. Many may run a novice level cycle numerous times and be happy with what they receive and that’s a good thing. The fewer anabolic steroids we can use and be happy with the better off we’ll be. Of course some will not be satisfied some will want more and that can be fine too; the ticket is having a solid plan in mind that provides those results in the most efficient way possible.
It should be noted that in theory if one was to consistently suppress your natural estrogen levels for a long period of time, this would negatively impact your health, including your cholesterol. Due to the ability of Letrozole- to inhibit estrogen so much, this should definitely be a concern to most users. However the research that has focused on the relationship between use of letrozole and cholesterol levels is rather inconsistent in it's findings. Many studies have concluded that the compound is detrimental to both a user's HDL and LDL cholesterol levels, while other research has found no link. Obviously individuals are best served to monitor their cholesterol while using any compound via blood tests however barring that, letrozole should simply not be run for extended periods of time if at all possible. Doing so could cause serious medical complications.
Along with the issues related to blood lipids is the fact that many users complain that their libido is dramatically reduced when using the compound. This is related to the fact that estrogen is partly responsible for the regulation of an individual's sex drive. Since Letrozole- is so potent it can often drive estrogen levels too low and this inhibits a user's libido. To avoid this users can lower dosages, but some anecdotally report that even extremely low doses of the drug can cause problems. If this is the case a less potent compound such as exemestane or anastrozole may be a more appropriate option.
