Mastaplex Drostanolone - Axiolabs

Buy Mastaplex 100 and Mastaplex 200 by Axiolabs at XSteroids. Mastaplex is the Axiolabs drostanolone range, offered as two esters: a fast propionate at 100 mg/ml and a slower enanthate at 200 mg/ml, each in a 10 ml multi-dose vial. Drostanolone is a dihydrotestosterone derivative that does not aromatize, which makes it a hardening and finishing compound rather than a mass builder. This guide covers both packs, injection frequency, how long each vial lasts, stacking and side effects.

Because it does not convert to estrogen, drostanolone adds no water and does not cause gynecomastia. Its effect depends on body condition: it shows a hard, dry, vascular look only when body fat is already low.

About Mastaplex (Drostanolone) by Axiolabs

Drostanolone is a synthetic androgen built on the dihydrotestosterone backbone. It is not a substrate for the aromatase enzyme, so it cannot be converted to estrogen, and it is also a poor substrate for other enzymes that amplify androgens. The result is a compound with modest anabolic action and a low androgenic load relative to many other steroids.

It has a medical past: drostanolone propionate was used to treat breast cancer in women, at doses as high as 200 mg twice a week, before it was withdrawn from the market. In bodybuilding it is used in contest preparation, not in the off-season.

How Mastaplex Works

Drostanolone binds the androgen receptor and supports protein synthesis, but its main visible effect is cosmetic. It helps give muscle a denser, harder appearance and can improve vascularity when body fat is low. It is not known for liver toxicity, and because it does not aromatize, it does not cause water retention.

Mastaplex 100 and Mastaplex 200

Mastaplex 100 - drostanolone propionate

The propionate ester clears in about two days, so it is injected at least every other day, sometimes daily in the final weeks of a prep. A 10 ml vial holds 1000 mg. At 300 mg per week it lasts about 3.3 weeks, at 400 mg per week about 2.5 weeks and at 600 mg per week about 1.7 weeks. The fast ester allows dose changes close to a show.

Mastaplex 200 - drostanolone enanthate

The enanthate ester has a half-life of about 7 to 10 days and is injected twice a week. A 10 ml vial holds 2000 mg. At 400 mg per week it lasts about 5 weeks, at 600 mg per week about 3.3 weeks. Levels peak around three to four weeks in, so this ester suits a longer cutting phase rather than a last-minute adjustment.

Mastaplex Doses and Cycle Guidelines

Propionate protocols generally run 300 to 600 mg per week over 6 to 10 weeks, with the first changes within one to two weeks. Enanthate protocols run 400 to 600 mg per week over 10 to 16 weeks, with a peak at three to four weeks. Either way, blood work before and during the cycle is the reliable way to judge tolerance.

How to Stack Mastaplex

Drostanolone is almost always run with a testosterone base to keep the hormonal picture balanced. Testaplex Testosterone supplies that base, and because drostanolone does not aromatize, it can partly offset estrogen from the base.

For a dry cutting look it pairs with other non-aromatizing compounds. Oxandroplex 10 mg and Stanoplex Stanozolol are common partners, while Proviraplex 25 mg is added for support on cycle. When the base requires it, an aromatase inhibitor such as Arimiplex 1 mg is used in a conservative dose.

PCT and Recovery After Mastaplex

Drostanolone suppresses natural testosterone production, so PCT is required. Timing follows the ester: allow a few days after the last propionate shot, and about two to three weeks after the last enanthate shot.

A standard protocol runs a SERM for four weeks, for example Tamoxiplex 20 mg or Clomiplex 50 mg. Recovery varies between users and natural levels can take months to return, so confirm progress with blood work rather than by how you feel.

Mastaplex Side Effects and Precautions

Androgenic effects

Because it is a dihydrotestosterone derivative, drostanolone can accelerate hair loss in users who are genetically predisposed to it, and it can worsen acne and oily skin. Body and facial hair growth is also reported. Men with a strong family history of male-pattern baldness are the most likely to notice this.

Lipids and suppression

Drostanolone tends to lower HDL cholesterol, which is a concern in an already lean cutting phase. It also suppresses natural testosterone production, which is why post cycle therapy is necessary. Regular blood work covers both the lipid and the hormonal side.

General precautions

This material is for adult men only, it is not medical advice, and anyone with heart, liver or prostate conditions should not self-administer hormones. Keep the vial out of the reach of children, and do not use a product that looks discoloured.

Storage Instructions

Store the vials at room temperature, roughly 20 to 25 C, in a dry place away from direct light and heat. Do not freeze oil-based solutions. Check the oil for particles before drawing, keep the rubber stopper clean, and always use a fresh sterile needle.
