Product Description
Healthy Medical Muscle Buildup Steroid Powder Drostanolone Propionate Masteron

Originally Dromostanolone (abbreviated to Drostanolone) known by trade name Masteron is an injectable oil-based anabolic steroid, derived from Dihydrotestosterone (DHT). It is a member of the DHT-derived family of anabolic steroids. Other known DHT-derivatives include: Winstrol, Anadrol, Anavar, Primobolan, and a few more.

There are two different variants of Masteron: 
Drostanolone Propionate
Drostanolone Enanthate

All anabolic steroid analogues and derivatives are derivates of the three natural anabolic steroids found in the human body.

There are principally two desirable effects of Testosteron: 
physical / athletic performance enhancement (endurance, strength, faster regeneration)
physique enhancement (muscle buildup, fat loss)
The rest of desirable testosterone effects that an individual might experience during the steroid cycle, include:
increase in collagen synthesis and bone mineral content. Collagen is the protein-based construction material for connective tissues throughout the body (the ligaments, tendons, cartilage, joints, and bones).
heightened self esteem
deeper (manly) voice
darkening and thickening of body hair
increased hemoglobin (red blood cell count)
anti-catabolic effect on muscle tissues by way of acting as an anti-glucocorticoid

Drostanolone Propionate Description

Drostanolone propionateis an ester of drostanolone. is indicated in post menopausal women with recurrent breast cancer, in combined hormone therapy.Drostanolone causes retention of nitrogen, potassium, and phosphorus; increases protein anabolism; and decreases amino acid catabolism.

The antitumor activity of drostanolone appears related to reduction or competitive inhibition of prolactin receptors
or estrogen receptors or production.

Masterone 100 USP injection provides drostanolone propionate, a potent androgenic steroid that has similar characterises of dihydrotestosterone. Drostanolone is incapable of aromization and therefore doesn't convert into oestrogen. Both drostanolone' anabolic and androgenic activity is far greater than methyl testosterone. The esterification of the 17-beta-hydroxyl group increases the duration of the action of drostanolone. Drostanolone esters in oil injected intramuscularly are absorbed slowly from the lipid phase, thus Masterone 100 can be administered at intervals of every 3-4 days.

Masterone 100 contains drostanolone propionate in a 10ml solution for injection (100mg drostanolone propionate / ml).

Masterone 100 is a yellowish oily solution for intramuscular injection.

Please kindly note, the Masterone 100mg/ml is pre-made injection steroid oil, you need to filter it then you can use it. 
If you don't know how to filter, don't worry, we will tell you how to filter it.

About how to filter

First, we can provide you great semi-finished oil, you just need to filter it and then you will get the best injection.
Second, i also can provide you high quality raw powders. Then i will help you convert powder into injection step
by step with the picture. It is easy for you , sure you can get it .

Step 1

Purchase syringe filter (most will filter 50-100ml depending on contaminants etc), if you don't have filter, we can send you with the oils for free.

Step 2

Sterilise top of vial
Draw up entire contents of vial into either a 10ml syringe or multiple 2.5ml
Draw up small amount of Iso alcohol into another syringe(0.25ml or so)
Put the iso alcohol into the vial and make sure to swirl it around.
Put a needle (no syringe) into the rubber stopper and let the iso alcohol vent

Step 3-

Now you have a sterile vial

Attach syringe filter to the syringe full of oil, attach a pin to the filter
Filter the oil into the vial (don't push too hard especially if you don't have luer lock syringes)

Filters retain 3ml of oil, so you will need 3ml of grapeseed oil to push through the hormone oil to make sure you don't lose any gear.

Step 4-

Your risk of getting one of these is now heavily reduced for a total cost of under £10!

Common Injectable Steroids:
While there are many injectable steroids available for purchase and use there are of course many far more common than others. Of the various forms there is none more common than testosterone and of course even the testosterone steroid can come in many injectable forms; in-fact, most injectable steroids have multiple forms, not all but most. Of the available injectable steroids the most common and really the only ones you will ever need to consider include:

Deca-Durabolin (Nandrolone-Decanoate)
Equipoise (Boldenone-Undeclynate)
Masteron (Drostanolone-Propionate)
NPP (Nandrolone-Phenylpropionate)
Omnadren (4 part Testosterone Mixture)
Parabolan (Trenbolone-Hexahydrobenzylcarbonate)
Primobolan Depot (Methenolone-Enanthate)
Sustanon-250 (4 part Testosterone Mixture)
Winstrol Depot 

Healthy Medical Muscle Buildup Steroid Powder Drostanolone Propionate Masteron
Actual use of Masteron 

Masteron is a modified form of Dihydrotestosterone, with a methyl group at the 2nd carbon (carbon alpha) atom. This modification is responsible for the anabolic strength increase. This methyl group makes it harder for the enzyme 3-hydroxysteroid dehydrogenase to metabolize Masteron. This enzyme is abundantly present in muscle tissue, and is responsible for degrading any DHT into two inactive metabolites: 3-Alpha Androstanediol and 3-Beta Androstanediol. Because of this enzyme DHT is not anabolic in muscle tissue at all. It is believed that if the enzyme 3-hydroxysteroid dehydrogenase was neutralized, DHT would actually be a very powerful anabolic steroid. Drostanolone's methyl group addition makes it imune to this enzyme. 

Masteron was initially marketed as a treatment of female breast cancer. Because it pronounced male characteristics in women and because more effective breast cancer treatments were invented, Drostanolone was gradually phased out.
