  • 98319-26-7 Finasteride , Pharma Grade Steroids For Transgender Women Excessive Hair Growth
Product Details:

Finasteride Medicine Raw Material Finasteride For Transgender women Excessive hair growth

 


Description

 

Finasteride, also known as 17β-( N - tert - butylcarbamoyl )- 4- aza - 5α - androst - 1 - en - 3 - one, is a synthetic androstane steroid and 4 - azasteroid. It is an analogue of androgen steroid hormones like testosterone and DHT.

 

Finasteride is a lipophilic compound.

 

 

Society and culture

 

The Food and Drug Administration advises that donation of blood or plasma be deferred for at least one month after taking the last dose of finasteride.

Harold Bornstein, Donald Trump's personal physician, stated Trump was taking finasteride to promote hair growth.

 

Athletics

 

From 2005 to 2009, the World Anti - Doping Agency banned finasteride because it was discovered that the drug could be used to mask steroid abuse. It was removed from the list effective January 1, 2009, after improvements in testing methods made the ban unnecessary. Athletes who used finasteride and were banned from international competition include skeleton racer Zach Lund, bobsledder Sebastien Gattuso, footballer Romário and ice hockey goaltender José Théodore.

 

Brand names

Drug trade names include Propecia, marketed for male pattern baldness ( MPB ), and Proscar, for benign prostatic hyperplasia ( BPH ); both are products of Merck & Co. There is 1 mg of finasteride in Propecia and 5 mg in Proscar. Merck's patent on finasteride for the treatment of BPH expired on June 19, 2006. Merck was awarded a separate patent for the use of finasteride to treat MPB. This patent expired in November 2013.

 

Controversy

Men in the US and Canada concerned about persistent sexual side effects "coined the phrase 'post finasteride syndrome', which they say is characterized by sexual, neurological, hormonal and psychological side effects that can persist in men who have taken finasteride for hair loss or an enlarged prostate". In 2012, a health advocacy group called the Post - Finasteride Syndrome Foundation was formed with the primary goal of finding a cure for the reported syndrome and a secondary goal of raising awareness. According to the company's 1Q2016 financial filing, Merck is a defendant in 1,385 product liability lawsuits which have been filed by customers alleging they have experienced persistent sexual side effects following cessation of treatment with finasteride.

Usage

 

Sexual dysfunction

 

Whether finasteride causes long - term sexual dysfunction in some men after stopping drug treatment is unclear. There are case reports of persistent diminished libido or erectile dysfunction after stopping the drug and the FDA has updated the label to inform people of these reports. A 2010 review found moderate quality evidence that finasteride increased the risk of sexual dysfunction, but not that people stopped using it because of sexual side effects.

 

When finasteride was originally approved for hair loss in 1997, the FDA approval review reported that it appears well tolerated, with the most common side effects being related to sexual function. In many people these side effects resolve if the medication is stopped and occasionally resolve even if the medication is continued. They additionally state " the sexual functioning questionnaire seems to have given a sensitive reflection of the disturbance on sexual functioning ".

 

A meta - analysis and systematic review found that sexual dysfunction, including erectile dysfunction, loss of libido, and reduced ejaculate, may occur in 3.4 to 15.8% of men treated with finasteride or dutasteride. This is linked to lower quality of life and can cause stress in relationships. There is also an association with lowered sexual desire. It has been reported that in a subset of men, these adverse sexual side effects may persist even after discontinuation of finasteride or dutasteride.

Product Details:

Low Toxicity P Acetophenetidide / Phenacetin 62-44-2 For Fever Headache Neuropathic Pain

 


Description

 

Phenacetin ( or acetophenetidin ) is a pain-relieving and fever - reducing drug, which was widely used between its introduction in 1887 and the 1983 ban imposed by the U.S. Food and Drug Administration.

 

Antipyretic analgesic, used to treat fever headache, neuropathic pain, etc. The effect of relieving heat is stronger than analgesic effect.The intensity of the drug is comparable to that of aspirin, which is slow and persistent and has low toxicity.The study showed that this product and its metabolite paracetamol have a pyrolytic effect.Because of the enzyme inhibitors, it can still show a clear thermal effect when it is not converted to acetaminophen.

 

Therefore, the pyrolytic effects of the products are not only produced by their active product paracetamol.The mild analgesic effect of phenacidine usually lasts 3-4 hours.The synergistic effect of the salicylic acid is enhanced.It is mainly used in the antipyretic analgesia of small animals.This product is also one of the components of APC tablets.

Tadalafil Powder Pharma Grade Steroids , CAS 171596-29-5 Sex Powder Tadalafil

  • Tadalafil Powder Pharma Grade Steroids , CAS 171596-29-5 Sex Powder Tadalafil
Product Details:

Tadalafil Medicine Raw Material For pulmonary arterial hypertension PDE5 Inhibitor C22H19N3O4

 

 

Description

 

Tadalafil is cyclic guanosine phosphate ( cGMP ) specific phosphodiesterase 5 ( PDE5 ) selectivity and reversible inhibitor, when sexual stimulation leads to partial release nitric oxide, tadalafil inhibit PDE5, make the penis sponge body cGMP level, resulting in smooth muscle relaxation, blood flow to the penis, produce an erection, such as asexual stimulation.

 

 

 

Selectivity compared with other PDE5 inhibitors

 

Tadalafil, sildenafil, and vardenafil all act by inhibiting the PDE5 enzyme. These drugs also inhibit other PDE enzymes. Sildenafil and vardenafil inhibit PDE6, an enzyme found in the eye, more than tadalafil. Some sildenafil users see a bluish tinge and have a heightened sensitivity to light because of PDE6 inhibition. Sildenafil and vardenafil also inhibit PDE1 more than tadalafil. PDE1 is found in the brain, heart, and vascular smooth muscle. It is thought that the inhibition of PDE1 by sildenafil and vardenafil leads to vasodilation, flushing, and tachycardia. Tadalafil inhibits PDE11 more than sildenafil or vardenafil. PDE11 is expressed in skeletal muscle, the prostate, the liver, the kidney, the pituitary gland, and the testes. The effects on the body of inhibiting PDE11 are not known.

 

 

 

Applications

 

1. Like its predecessor Viagra, Cialis is used to treat erectile dysfunction in men.

2. One of the more embarrassing side effects of post - cycle - therapy is the decreased libido caused by the sudden absence of exaggerated testosterone levels in the body, often leading to ED. If you cann't get it up after your cycle, get the pill.

3. Tadalafil is the raw material of cialis.

4. Cialis is a kind of male sex enhancer drug.

5. Cialis is much longer lasting than Viagra. Effects can be felt anywhere between 36-48 hours.

6. Cialis works by aiding relaxation of blood vessels and increasing blood flow in the penis during sexual arousal, resulting in improved erectile function

 

Chemistry

 

Tadalafil is an annulated 2,5- diketopiperazine. It is also a 1,2,3,4- tetrahydro - β - carboline.

Tadalafil can be synthesized starting from ( D ) - tryptophan methyl ester and piperonal via a Pictet – Spengler reaction. This is followed by condensations with chloroacetyl chloride and methylamine to complete the diketopiperazine ring

Valsartan Powder Pharma Grade Steroids For Antihypertensive CAS 137862-53-4

  • Valsartan Powder Pharma Grade Steroids For Antihypertensive CAS 137862-53-4
Product Details:

Valsartan powder Medicine Raw Material for Antihypertensive CAS 137862-53-4

 

 

Description

 

1. Valsartan ( trade name Diovan ) is an angiotensin II receptor antagonist (commonly called an ARB, or angiotensin receptor blocker ), that is selective for the type I ( AT1 ) angiotensin receptor. Valsartan is mainly used for treatment of high blood pressure, congestive heart failure, and to increase the chances of living longer after a heart attack.

2. Valsartan is used alone or in combination with other medications to treat high blood pressure. It is also used to treat heart failure ( condition in which the heart is unable to pump enough blood to the rest of the body ) and to improve survival after a heart attack. Valsartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.

3. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.

 

Standard

 

USP EP BP CP

 

 

Application

 

1. Valsartan is an angiotensin II receptor antagonist. Valsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow. Valsartan is used to treat high blood pressure ( hypertension ) in adults and children who are at least 6 years old. Valsartan is also used in adults to treat heart failure, and to lower the risk of death after a heart attack. Valsartan is sometimes given together with other blood pressure medications.
Valsartan may also be used for purposes not listed in this medication guide.

2. Valsartan is used to treat high blood pressure and heart failure. It is also used to improve the chance of living longer after a heart attack. In people with heart failure, it may also lower the chance of having to go to the hospital for heart failure. Valsartan belongs to a class of drugs called angiotensin receptor blockers ( ARBs ). It works by relaxing blood vessels so that blood can flow more easily. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.

3. Valsartan is used to treat high blood pressure, congestive heart failure, and to reduce death for people with left ventricular dysfunction after having had a heart attack.There is contradictory evidence with regard to treating people with heart failure with a combination of an angiotensin receptor blocker like valsartan and an angiotensin - converting enzyme inhibitor, with two major clinical trials ( CHARM - additive and ValHeFt ) showing a reduction in death, and two others ( VALIANT and ONTARGET ) showing no benefits, and more adverse effects including heart attacks. In people with type II diabetes and high blood pressure or albumin in the urine, valsartan is used to slow the worsening and the development end - stage renal disease.

Valsartan Pharma Grade Steroids For Posterior Myocardial Infarction

  • Valsartan Pharma Grade Steroids For Posterior Myocardial Infarction
Product Details:

Valsartan Medicine Raw Material for Treat Posterior Myocardial Infarction primary hypertension

 

 

Description

 

Valsartan is an angiotensin II receptor antagonist antihypertensive drugs, the drug is a make angiotensin Ⅱ type 1 ( AT1 ) receptor blockade, angiotensin Ⅱ plasma levels, stimulate non - sealing AT2 receptors, against the effect of AT1 receptor at the same time, so as to achieve to dilate blood vessels the effect of lowering blood pressure.

 

In the United States, valsartan is a drug used to treat hypertension, congestive heart failure and post - myocardial infarction.

 

Switzerland ciba - fine base company research and development production of the generation of valsartan in 1995 and 1996, respectively, to obtain a patent in the United States and Europe, and in July 1996 for the first time to market in Germany, then gradually in Europe, America, Japan. Valsartan has the characteristics of stable hypotension effect and small toxicity.

 

 

Medical uses

 

Valsartan is used to treat high blood pressure, congestive heart failure, and to reduce death for people with left ventricular dysfunction after having had a heart attack.

 

In people with type II diabetes and high blood pressure or albumin in the urine, valsartan is used to slow the worsening and the development end-stage renal disease.

 

 

Mechanism of action

 

Valsartan blocks the actions of angiotensin II, which include constricting blood vessels and activating aldosterone, to reduce blood pressure. The drug binds to angiotensin type I receptors ( AT1 ), working as an antagonist. This mechanism of action is different than the ACE inhibitor drugs, which block the conversion of angiotensin I to angiotensin II.

 

Since valsartan acts at the receptor, it can provide more complete angiotensin II antagonism since angiotensin II is generated by other enzymes as well as ACE. Also, valsartan does not affect the metabolism of bradykinin like ACE inhibitors do.

Product Details:

P Ethoxyacetanilide Medicine Raw Material For Relieving Fever / Reducing Drug CAS 62-44-2

 


Description


Phenacetin, ( Phenacetin, or acetophenetidin ), chemical formula C10H13NO2, is a white crystalline solid at room temperature, melting point 134 ℃, is a by many countries to ban drugs. Phenacidine is a white, shiny flake crystal or white crystalline powder. The melting point of 137-138 ℃, the refractive index of 1.571. Insoluble in water, slightly soluble in ether, slightly soluble in boiling water, dissolved in ethanol and chloroform. When dissolved in concentrated sulfuric acid, it does not show color, and when it drops into the solution, it is orange. Odorless, bitter taste.

 

 

Known mechanism of action

 

Its analgesic effects are due to its actions on the sensory tracts of the spinal cord. In addition, phenacetin has a depressant action on the heart, where it acts as a negative inotrope. It is an antipyretic, acting on the brain to decrease the temperature set point. It is also used to treat rheumatoid arthritis ( subacute type ) and intercostal neuralgia.

It is metabolized in the body as paracetamol ( acetaminophen ), which is also a clinically relevant analgesic.


Use

 

Phenacetin was widely used until the third quarter of the twentieth century, often in the form of an "A.P.C." or aspirin - phenacetin - caffeine compound analgesic, as a remedy for fever and pain. An early formulation ( 1919 ) was Vincent's APC in Australia. However the U.S. Food and Drug Administration ordered the withdrawal of drugs containing phenacetin in November 1983, owing to its carcinogenic and kidney - damaging properties ( Federal Register of October 5, 1983 ( 48 FR 45466 ) ). It was also banned in India. As a result, some branded, previously phenacetin - based preparations continued to be sold, but with the phenacetin replaced by safer alternatives.

 

A popular brand of phenacetin was Roche's Saridon, which was reformulated in 1983 to contain propyphenazone, paracetamol and caffeine. Coricidin was also reformulated without phenacetin. Paracetamol is a metabolite of phenacetin with similar analgesic and antipyretic effects, but the new formulation has not been found to have phenacetin's carcinogenicity.

 

Phenacetin is now being used as a cutting agent to adulterate cocaine in the UK and Canada, owing to the similar physical features of the two drugs.

 

Due to low - cost phenacetin is used for research into the physical and refractive properties of crystals. It is an ideal compound for this type of research.
