Levothyroxine

Levothyroxine, also known as L-thyroxine, is a manufactured form of the thyroid hormone, thyroxine (T4). It is used to treat thyroid hormone deficiency including the severe form known as myxedema coma. It may also be used to treat and prevent certain types of thyroid tumors. It is not indicated for weight loss. Levothyroxine is taken by mouth or given by injection into a vein. Maximum effect from a specific dose can take up to six weeks to occur.
Side effects from excessive doses include weight loss, trouble tolerating heat, sweating, anxiety, trouble sleeping, tremor, and fast heart rate. Use is not recommended in people who have had a recent heart attack. Use during pregnancy has been found to be safe. It is recommended that dosing be based on regular measurements of TSH and T4 levels in the blood. Much of the effect of levothyroxine is following its conversion to triiodothyronine (T3).

Methylhexanamine

Methylhexanamine (trade names Forthane, Geranamine) or methylhexamine, commonly known as 1,3-dimethylamylamine (1,3-DMAA) or simply dimethylamylamine (DMAA), is an indirect sympathomimetic drug invented and developed by Eli Lilly and Company and marketed as an inhaled nasal decongestant from 1944 until it was voluntarily withdrawn from the market in 1983.

 

Since 2006 methylhexanamine has been sold extensively under many names as a stimulant or energy-boosting dietary supplement under the claim that it is similar to certain compounds found in geraniums, but its safety has been questioned as a number of adverse events and at least five deaths have been associated with methylhexanamine-containing supplements. It is banned by many sports authorities and governmental agencies.

Dihydrotestosterone (DHT)

Dihydrotestosterone (DHT), or 5α-dihydrotestosterone (5α-DHT), also known as 5α-androstan-17β-ol-3-one, is an endogenous androgen sex steroid and hormone. The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, hair follicles, liver, and brain. This enzyme mediates reduction of the C4-5 double bond of testosterone. Relative to testosterone, DHT is considerably more potent as an agonist of the androgen receptor (AR).

Methocarbamol

Methocarbamol is a central muscle relaxant used to treat skeletal muscle spasms. Under the trade name Robaxin, it is marketed by Actient Pharmaceuticals in the United States and Pfizer in Canada. The mechanism of action of methocarbamol is currently unknown, but may involve the inhibition of carbonic anhydrase. The muscle relaxant effects of methocarbamol are largely attributed to central depressant effects; however, peripheral effects of methocarbamol to prolong muscle refractory period have also been reported.

Metabolism

 

Methocarbamol is the carbamate of guaifenesin, but does not produce guaifenesin as a metabolite, because the carbamate bond is not hydrolyzed metabolically; metabolism is by Phase I ring hydroxylation and O-demethylation, followed by Phase II conjugation. All the major metabolites are unhydrolyzed carbamates.

Amlodipine

Amlodipine, sold under the brand name Norvasc among others, is a medication used to treat high blood pressure and coronary artery disease. While calcium channel blockers are not typically recommended in heart failure, amlodipine may be used if other medications are not sufficient for high blood pressure or heart related chest pain. Amlodipine is taken by mouth and has an effect for at least a day.

 

Common side effects include: swelling, feeling tired, abdominal pain, and nausea. Serious side effects may include low blood pressure or a heart attack. It is unclear if use is safe during pregnancy or breastfeeding. Doses should be decreased in people with liver problems and those who are old. Amlodipine is a long acting calcium channel blocker of the dihydropyridine type. It works partly by increasing the size of arteries.

 

Medical uses

Amlodipine is used in the management of hypertension[7] and coronary artery disease (chronic stable angina, vasospastic angina, and angiographically documented CAD without heart failure or ejection fraction < 40%.) It can be used as either monotherapy or combination therapy for the management of hypertension or coronary artery disease. Amlodipine can be administered to adults and children 6–17 years of age.

Dehydroepiandrosterone (DHEA)

Dehydroepiandrosterone (DHEA), also known as androstenolone or as prasterone (INN), is an endogenous steroid hormone. It is one of the most abundant circulating steroids in humans, in whom it is produced in the adrenal glands, the gonads, and the brain, where it functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids. However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors, and acting as a neurosteroid and neurotrophin. DHEA is also used orally as a medication and dietary supplement, to restore or increase DHEA and DHEA sulfate (DHEA-S) levels.

Application: For the synthesis of steroid hormone drugs.
Dehydroepiandrosterone acetate is an important intermediate for the synthesis of various hormones, family planning supplies and other steroid hormones. Also used as an important intermediate for the synthesis of testosterone, methyl testosterone, β -estradiol, Estriol.

Pregnenolone

Pregnenolone is a natural hormone that cannot be patented. Back in the 1940's, when researchers started experimenting with it, they realized that it could be helpful for people under stress and it could increase energy in those who were fatigued. However, about the same time, cortisol, another closely related hormone, was discovered.

Halodrol

Halodrol also known as 4-chloro-17a-methyl-androst-1,4-diene-3b,17b-diol, or HD is an excellent compound for adding lean hard muscles as well as strength gains. Halodrol is good for improved vascularity, dry gains with only a small to no amount of water retention.

Halodrol exhibits an extremely high anabolic to androgenic ratio translating into hard and consistent muscle gains with No aromatization. These gains are notably extremely lean and dry in nature, making this a favorite for the pre-contest athlete, or as an anabolic addition to many stacks. Mainly used to increase muscle mass most particularly in the abdomen region and will increase muscle endurance and decrease your recovery time after workouts.

4-AcO-DMT

O-Acetylpsilocin (also known as psilacetin, 4-acetoxy-DMT, or 4-AcO-DMT) is a synthetically produced psychoactive drug and has been suggested by David Nichols to be a potentially useful alternative to psilocybin for pharmacological studies, as they are both believed to be prodrugs of psilocin. However, some users report that O-acetylpsilocin's subjective effects differ from that of psilocybin and psilocin. It is the acetylated form of the psilocybin mushroom alkaloid psilocin and is a lower homolog of 4-AcO-MET, 4-AcO-DET, 4-AcO-MiPT and 4-AcO-DiPT.

Bk-2C-B

βk-2C-B (also known as Bk-2C-B, or beta-keto 2C-B) is a novel synthetic psychedelic substance of the phenethylamine chemical class that produces psychedelic effects comparable to members of the 2C-x family when administered.

Pharmacology

Bk-2C-B likely acts as a 5-HT2A partial agonist. The psychedelic effects are believed to come from its efficacy at the 5-HT2A receptors. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Norandrostenedione

Bolandione, also known as 19-norandrostenedione, as well as 19-norandrost-4-en-3,17-dione or estr-4-ene-3,17-dione, is a precursor of the anabolic-androgenic steroid (AAS) nandrolone (19-nortestosterone). Until 2005, bolandione was available without prescription in United States, where it was marketed as a prohormone, but it is now classified as a Schedule III drug. It is also banned from use in many sports, including the Olympic Games, under the World Anti-Doping Code. Bolandione is readily metabolized to nandrolone after oral administration, but its potency to transactivate the androgen receptor dependent reporter gene expression is 10 times lower as compared to dihydrotestosterone (DHT).

Equine chorionic gonadotropin

Equine chorionic gonadotropin (acronym given as eCG but not to be confused with ECG) is a gonadotropic hormone produced in the chorion of pregnant mares. Previously referred to as pregnant mare's serum gonadotropin (PMSG), the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.
