Proviron Dosage and Indications
Indications (reasons it is normally prescribed):
Typically prescribed to supplement testosterone, usually in cases of infertility or as an anti-aging treatment or as part of a treatment plan for gynecomastasia (male breast growth).
Contraindications (Conditions which cause it to be high risk to take proviron):Contraindicated in patients with prostate cancer, breast cancer, tumor in liver, during pregnancy and breastfeeding.
The typical dose for Proviron is 100mg/day, at that dose it does a great job at fending off gyno side effects caused by the aromatization of other more potent anabolics that are stacked alongside it.
DHT Based Proviron
Due to Proviron being based on DHT it is readily reduced to inactive metabolites in muscle tissue, this is why Proviron has such low androgenic function, but also a part of how proviron enhances the effects of other anabolic steroids it is stacked with. Because the enzymes responsible for breaking down excess testosterone are otherwise occupied the other anabolics an athlete is taking are free to act on the muscle.
Proviron Lab Studies
It has been noticed in lab tests that at a dose of 100mgs/day Proviron by itself has no effect on FSH and LH levels in the blood. FSH and LH are the two hormones that instruct your body to produce testosterone. With that property, Proviron is a popular choice for bridging. Bridging is the practice of slowly stepping down dosage of external testosterone while supplementing with something that does not suppress natural testosterone production, it has also been noticed that Proviron actually raises the user’s LH levels. As such Proviron is one of the best bridging supplements that there is.
When prescribed, Proviron is usually prescribed to treat sexual dysfunction (including low sperm count, impotency, and sexual disintrest) caused by low endogenous (natural) testosterone, in that role Proviron excels and does so with relative safety. Occasionally Proviron will be used as a treatment for gynecomastasia as well.
Androgenic / Anabolic Ratio
With it’s Androgenic / Anabolic Ratio of 30-40/100-150 Proviron is highly androgenic, meaning it has a much more profund effect on sexual traits than it does on muscle building.
Due to it’s highly androgenic (sexual characteristic altering) abilities as well as it’s estrogen blocking capabilities, Proviron is not recommended for women that are not looking for Masculine traits, however, for women attempting to be more masculine, it’s probably a great idea.
