This product is not an anabolic/androgenic steroid. It is however widely used by bodybuilders. Nolvaxyl belongs to the group of sex hormones and is a so-called antiestrogen. Its normal application is in the treatment of certain forms of breast cancer in female patients. Bodybuilders who take Nolvaxyl also use anabolic steroids at the same time. Since most steroids aromatize more or less strongly, i.e. part of the substance is converted into estrogens, male bodybuilders can experience a significant increase in their normally very low estrogen level. This can lead to feminization symptoms such as gynecomastia (growth of breast glands), increased fat deposits and higher water retention.
Nolvaxyl by Kalpa Pharmaceuticals works against this by blocking the estrogen receptors of the affected body tissue, inhibiting a bonding of estrogens and receptor. Tamoxifen does not prevent the aromatization but only acts as an estrogen antagonist. This means that it does not prevent testosterone and its synthetic derivatives (steroids) from converting into estrogens but only fights with them in a sort of “competition”for the estrogen receptors. This characteristic has the disadvantage that after the discontinuance of Nolvaxyl a “rebound effect” can occur which means that the suddendly freed estrogen receptors are now able to absorb the estrogen present in the blood. For this reason the combined intake of Proviron is suggested. Tamoxifen is also useful during a diet since it helps in the burning of fat. Although it has no direct fat-burning effects, its antiestrogenic effect contributes to keeping the estrogen level as low as possible.
Tamoxifen should especially be taken together with the strong androgenic steroids Dianabol and Anadrol, and the various testosterone compounds. Athletes who have a tendency to retain water and who have a mammary dysfunction should take Nolvaxyl as a prevention during every steroid intake. Since this product is very effective, in most cases athletes take Anadrol and Dianabol until the day of a competition, and in combination with a diruretic appear totally ripped. Those who already have a low body fat content will achieve a visibly improved muscle hardness with Nolvaxyl.
Several bodybuilders like to use Nolvaxyl at the end of a steroid cycle since it increases the body’s own testosterone production.
A disadvantage proper of Tamoxifen is that it can weaken the anabolic effect of some steroids.
The side effects of Nolvaxyl are usually low in dosages of up to 30 mg/day. In rare cases nausea, vomiting, hot flashes, numbness, and blurred vision can occur. The normal daily dosage taken by athletes corresponds more or less to the dosage indications of the manufacturer and is 10-30 mg/day. To prevent estrogenic side effects normally 10 mg/day are sufficient, a dosage which also lowers the risk of reducing the effect of simultaneously-taken steroids.
