Drostanolone - Geneza Pharmaceuticals

Buy Drostanolone by Geneza Pharmaceuticals at XSteroids. Two vials sit on this page, propionate 100 and enanthate 200, both holding drostanolone, the dihydrotestosterone derived steroid that bodybuilding knows as Masteron. The page sets out what each vial is, how a compound that cannot become estrogen behaves, what a course tends to look like, how the two esters are dosed, what runs beside them, how the axis is restarted and how the vials are stored.

Geneza Pharmaceuticals ships these vials for laboratory and bodybuilding reference. Drostanolone is a controlled substance, no longer sold as a medicine anywhere, so the material below describes published pharmacology and community practice rather than a prescription.

What the Geneza Drostanolone Vials Are and What You Are Buying

Propionate 100 and enanthate 200 are the same steroid with different release speeds. The propionate leaves the depot within a couple of days and suits frequent injections; the enanthate ester is the slower of the two and is usually pinned less often. Both come as 10 ml multi-dose vials carrying the Geneza Pharmaceuticals label with a batch code and an expiry date.

History is worth knowing here. Drostanolone was once approved by the FDA as an antioestrogenic agent for advanced, inoperable breast cancer in women, with oncology doses reaching 200 mg twice weekly. It is no longer marketed as a medicine. No independent assay of these lots has appeared, so the printed strength remains a label claim.

How Drostanolone Works Without Converting to Estrogen

The molecule is built on the dihydrotestosterone frame, and that structure cannot be aromatised, so no estradiol is produced and no water is held behind it. Its anabolic action is moderate while its androgenic action is weak, which is why the side effect profile is generally described as mild for an injectable steroid. Hepatotoxicity is not part of the picture for this compound.

Its antioestrogenic effect is real but indirect: the drug suppresses the growth of oestrogen receptor positive tissue through its own androgenic signal rather than by blocking the aromatase enzyme. In practical terms that means it does not lower estradiol on a blood test the way an aromatase inhibitor does, and users who expect that will misread their results.

What to Expect from Masteron 100 and Masteron 200

Drostanolone is a finishing compound. When body fat is already low, users describe a drier, tighter and harder appearance, with veins more visible and strength holding steady in a calorie deficit. When body fat is high, the visible change is close to none, because there is no subcutaneous fluid to remove and nothing to reveal.

The natural axis is suppressed while the drug is present, so libido depends heavily on the testosterone running alongside it. Muscle gain from Masteron alone is modest and slow. Anyone buying it hoping for a mass phase is buying the wrong product, and anyone combining it with a wet compound is cancelling its main advantage.

Dosing Drostanolone Propionate and Enanthate

Weekly amounts reported in practice run from roughly 200 to 500 mg, with the propionate usually split across several injections because of its short action and the enanthate pinned once or twice a week. The oncology figure of up to 200 mg twice weekly belongs to a different context and should not be copied as a physique dose.

Choosing between propionate and enanthate

Propionate 100 gives fine control of the weekly total and a fast exit if the amount is wrong, at the cost of more injections. Enanthate 200 keeps the level steadier with fewer shots. The half-life of the propionate is about two days; public pharmacokinetic data for the enanthate are thinner, so no precise figure is claimed here.

Two practical points decide how the vials are used. The first is injection frequency: propionate needs attention several times a week while enanthate does not, and skipping that routine flattens the level the compound depends on. The second is the fat percentage already on the frame, since the visible return of a dry compound rises sharply as body fat falls.

Stacking Masteron Behind a Testosterone Base

Testosterone is the base, and Testosterone Esters and Suspension from Geneza Pharmaceuticals covers propionate, enanthate, cypionate, suspension and undecanoate, so the base speed can be matched to the Masteron ester. GP Sust 270 is the blended alternative for a longer interval.

For a cutting phase the usual partner is a dry oral: Stanozolol tablets or Oxandrolone. Where a lean mass phase is planned instead, GP Bold 300 adds tissue on a timeline the base can carry.

Recovery After the Last Drostanolone Injection

Suppression of endogenous testosterone is expected, so a restart is planned once the ester has cleared. Propionate clears in a few days and allows the earliest start; enanthate needs a longer wait because release continues after the final shot. SERM treatment is the community standard, and blood work is the only way to know whether it has worked.

GP Nolvadex (tamoxifen) and GP Clomiphene are the two products kept for that stage, and either can carry it. Running another suppressive compound during recovery defeats the purpose, and lengthening the window is safer than shortening it.

Drostanolone Side Effects and Precautions

The androgenic side of the profile shows up as acne, oily skin and accelerated hair loss in men who are genetically prone to it, and a deepening voice and clitoral enlargement in women, for whom the compound is a poor choice. Prostate symptoms deserve attention in older users, and lipids are worth monitoring since the oral and injectable androgens both shift them.

There is no described hepatotoxicity for drostanolone, and no aromatisation, so gynaecomastia from this compound alone is not the expected problem. It is a US Schedule III controlled substance and a WADA class S1 banned substance, so non-medical use is unlawful in most countries and impossible in tested sport.

Storage Instructions

Store both vials upright with the caps sealed, at room temperature in a dry place away from direct light, damp air and heat sources. An oil based injection never belongs in a freezer and does not need a refrigerator. Note the lot number and expiry when the order arrives, and bin any vial that is cloudy, discoloured or leaking around the stopper.

Why Buy Geneza Drostanolone from XSteroids?

Both esters are listed in the same Geneza Pharmaceuticals category as the base, the dry orals and the SERMs a cutting phase uses, so the whole plan fits one basket. Parcels are dispatched the same day in plain outer packaging; most US deliveries arrive inside three to six days, and shipments to other countries take twelve to twenty-six. The related cards below show the usual combinations, and the propionate or enanthate choice sets how often a shot is needed.
