pharmaceutical raw material 99% methyl drostanolone steroids powder

description :

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. drostanolone (masteron) is considered a moderate strength anabolic steroid with anabolic rating: 62 - 130 and low androgenic strenght: 25 - 40.

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:

biochemistry of masteron / drostanolone

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.

drostanolone is injected into the body as an ester (bonded to either propionate or enanthate). enzymes cleave off the ester from the masteron molecule - which takes varying amount of time depending on which ester was used. this process causes the gradual release rate and extended half-life of the steroid. drostanolone propionate has a half-life of 2.5 days, while drostanolone enanthate has a half-life of 10 days.

intended use of drostanolone / masteron

• testosterone
• dihydrotestosterone
• nandrolone

our process:
the quality control process
1)purchasing
thorough market research, understand the price of raw materials and performance.to the procurement source to understand fully, and fully guarantee the quality of the procurement of raw materials.
2) inspection
four steps: sampling, sample pretreatment, measuring and data processing.
3) producing
a)each operator must do self-inspection of producs and make the corresponding inspection records.
b)full-time inspectors through check the operator self-inspection, and review and sign in the corresponding record. full-time inspection is responsible for inspection of finished product, and make the finished product incoming inspection records.
4) before selling
test result can be provided before selling.
third-party detection institution is allowed if you are not satisfied with test results.
