Nolvadex is widely available and one of the easiest items on earth to obtain. In the . it is not classified as controlled substance; however, true legal possession will require a prescription. On the black market, nearly all anabolic steroid suppliers carry the SERM and counterfeits, while possible appear to be very rare. The SERM as with many related items is also available through research chemical labs (RCL’s). These RCL’s have found a loophole in the law that allows them to legally manufacture and sell SERM’s, AI’s, Peptides and many other items so as long as it’s for research only. This allows anyone to make a related purchase without a prescription and legally so. However, many of these RCL’s are very low grade. It’s common for their products to lose potency fast, to be unstable, and in some cases, so heavily concentrated they’re hard to dose. While there is a lot of garbage out there, there are quite a few very good RCL’s on the market. A little digging and you’ll easily find one.
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.
Trenbolone is very androgenic and although it is classified as an anabolic it is more androgenic than most testosterones. Trenbolone is a very interesting drug because it does not aromatize into estrogen at all. The advantage of this is of great value because it means that there is no water retention. Trenbolone does however have an affinity for the progesterone receptor. The side effects of progesterone are similar to that of estrogen. Progesterone causes negative feedback from the HPTA axis and therefore suppresses endogenous testosterone production
