Q: “What is the situation with Nolvadex or Clomid use and vision problems? Is it okay to continue their use when problems first start, if they do, or should I discontinue immediately?”
A: It probably is the case that not only Nolvadex and Clomid but all SERMs can cause vision problems on a dose-dependent basis. The problems can include changes in color vision and appearance of “floaters.” These problems appear to occur from estrogen-receptor related effects on retinal and lens cells.
At the most basic level, these cells experience protective effects from activation of estrogen receptor beta. Ordinarily speaking, even a male with relatively low estrogen still has significant activation of this receptor, and the protective benefits are enjoyed. Where a SERM is used at relatively high dose and on top of this estradiol levels are low, receptor activation may be essentially abolished or certainly becomes abnormally low.
Where SERM dosage is high, as is often the case with breast cancer patients, the rate of vision problems is much higher than it is in bodybuilding, where doses are generally lower. As an example of dose dependency, in Documenta Ophthalmologica, Volume 120 (2) – Apr 1, 2010 no vision problems were found in their particular group women taking tamoxifen at 20 mg/day, while many papers have found a high rate of problems at higher doses.
I absolutely recommend ceasing SERM use immediately upon detecting any change in vision, regardless that the PCT program has not been completed.
While the anti-aromatase approach to PCT is inferior to the SERM approach, it becomes the remaining option and it can work (I’m assuming here that testicular function remains good; if not then this must be addressed with HCG treatment.) Use blood values to determine dosage providing blood E2 levels from the mid teens to no more than the low 20s. (Ordinarily, estradiol levels are best kept in the 20s, but in this situation the duration of low values will be short, and will aid recovery.)
To have high likelihood of avoiding any problem, other than the first day of frontloading, don’t exceed 20 mg/day Nolvadex use, or 50 mg/day Clomid use.
About the author
Bill Roberts is an internationally-recognized expert on anabolic steroids and performance-enhancing drugs (PEDs). He received a bachelor degree in Microbiology and Cell Science and completed the educational and research requirements for a PhD in Medicinal Chemistry at a major American university.
Bill entered the nutritional supplement industry prior to completing his doctoral thesis but his education was invaluable so far as being able to design/improve nutritional supplement compounds, since it was in the field of designing drug molecules and secondarily some work in transdermal delivery.
His education was not specifically "geared" toward anabolic steroids other than expertise with pharmacological principles having broad applications. This has allowed Bill to provide unique insight into the field of anabolic pharmacology with knowledge of points which he would not have known otherwise.
