Mesterolone (Proviron) (5 Offers)

What Is Mesterolone?

Mesterolone is a synthetic, orally active androgen derived from dihydrotestosterone (DHT). It has historically been marketed under the name Proviron and is generally supplied as tablets with the labeled amount of active substance expressed in milligrams per tablet.

Mesterolone differs pharmacologically from many of the oral anabolic steroids found elsewhere in the catalog. Product names, tablet strengths, package quantities and manufacturers can also vary, making the active-substance listing and complete product specification useful when comparing available options.

Mesterolone & Proviron

Mesterolone identifies the active substance, while Proviron is the trade name widely associated with it. Individual manufacturers may use Proviron or their own product-specific branding for tablets containing mesterolone.

Products using different names can therefore contain the same active substance while differing in labeled tablet strength, package quantity, manufacturer, price and laboratory testing history. Checking the listed substance provides a more reliable basis for comparison than the product name alone.

A DHT-Derived Oral Androgen

Mesterolone is structurally related to dihydrotestosterone (DHT). Unlike many oral anabolic steroids, mesterolone is not a 17α-alkylated steroid. This is an important distinction when comparing its chemical structure with oral compounds such as methandienone, oxymetholone, stanozolol or fluoxymesterone.

Mesterolone is nevertheless a pharmacologically active androgen. Differences in structure should not be interpreted as meaning that it is free from endocrine, cardiovascular, reproductive or androgen-related adverse effects.

Mesterolone & Aromatization

Mesterolone does not undergo aromatization to estrogen. This is consistent with its DHT-derived structure and distinguishes it from aromatizable androgens such as testosterone.

The absence of aromatization describes one pharmacological characteristic rather than the overall safety of the substance. Mesterolone can still produce androgenic and endocrine effects and should not be considered risk-free because it does not convert to estrogen.

Comparing Mesterolone Products

When browsing Mesterolone products, useful comparison points include the labeled amount per tablet, total tablet count, manufacturer, current price, warehouse location and published laboratory testing where available.

Two products containing mesterolone can use different package sizes or manufacturer-specific branding even when their labeled tablet strengths are similar. Reviewing the complete specification makes comparison easier than relying on the Proviron name or price alone.

Tablet Strength vs. Package Quantity

The labeled mg-per-tablet strength identifies the amount of mesterolone stated in each tablet. Package quantity separately identifies the total number of tablets supplied.

These specifications should be considered independently. Products with the same tablet strength can be supplied in different quantities, while similarly sized packages can contain tablets with different labeled strengths.

Published Mesterolone Lab Reports

Selected Mesterolone products have published laboratory reports that provide an additional point of reference when comparing the labeled specification with the measured amount reported for a submitted sample.

Where testing is available, review the measured result, test date and reported batch number. If multiple reports have been published for the same product, results from different testing dates or batches can also be reviewed individually.

Each laboratory report applies to the submitted sample identified in that analysis. A result from one sample does not independently verify every tablet, package or future production batch.

Mesterolone Safety Information

Mesterolone is an active androgen and can cause clinically relevant adverse effects. Potential concerns include androgen-related effects involving the skin, hair and other androgen-sensitive tissues, as well as effects on natural hormone regulation and reproductive function.

Androgen exposure can also affect cardiovascular risk factors, including blood lipids. Individual risk depends on health history, existing medical conditions, other medications or substances and the extent of exposure.

Although mesterolone is not a 17α-alkylated oral steroid, this structural distinction should not be interpreted as evidence that unsupervised use is safe. Product quality and pharmacological safety are also separate considerations: a laboratory report can provide information about a tested sample without establishing that use of the substance is appropriate for an individual.

This category is intended to help identify and compare available products and does not provide individualized dosing, cycle or administration guidance.

Mesterolone in Tested Sport

Mesterolone is prohibited under anti-doping rules in tested sport. Its prohibited status applies regardless of manufacturer, product name, tablet strength or whether the product is marketed using the Proviron name.

Athletes subject to anti-doping testing should check the current regulations applicable to their sport before using a product containing mesterolone or another prohibited androgenic substance.

USA Domestic & International Availability

Mesterolone products may be available from the USA Domestic Warehouse, the International Warehouse, or both. Available manufacturers, strengths and stock levels can differ between warehouse locations.

For delivery within the United States, USA Domestic shipments typically take 4–5 business days after dispatch, while International Warehouse shipments typically take 15–20 business days after dispatch.

Delivery estimates begin after dispatch and do not include order processing time. Additional delivery, tracking and reship information is available on the Shipping Information page.

Ordering & Crypto Payment

Bitcoin and other supported cryptocurrencies are available at checkout for all orders. Before ordering a Mesterolone product, compare its manufacturer, tablet strength, package quantity, current price, available laboratory reports and warehouse location.

Where the store's separate crypto discount applies, eligibility depends on the current pricing status of the product. Already discounted products should not automatically be assumed to qualify for an additional discount.
