In the U.S., black-market importation continues from Mexico, Thailand, and other countries where steroids are more easily available, as they are legal. Research
AAS, alone and in combination with progestogens, have been studied as potential male hormonal contraceptives. Dual AAS and progestins such as trestolone and dimethandrolone undecanoate have also been studied as male contraceptives, with the latter under active investigation as of 2018.Topical androgens have been used and studied in the treatment of cellulite in women. Topical androstanolone on the abdomen has been found to significantly decrease subcutaneous abdominal fat in women, and hence may be useful for improving body silhouette. However, men and hyperandrogenic women have higher amounts of abdominal fat than healthy women, and androgens have been found to increase abdominal fat in postmenopausal women and transgender men as well.

During periods of fasting, fatty acids are also an important energy source for the liver and other tissues.Mutations in the HADHA or HADHB genes that cause mitochondrial trifunctional protein deficiency disrupt all functions of this enzyme complex. Without enough of this enzyme complex, long-chain fatty acids cannot be metabolized. As a result, these fatty acids are not converted to energy, which can lead to some features of this disorder. Long-chain fatty acids may also build up and damage the liver, heart, and muscles. This abnormal buildup causes other symptoms of mitochondrial trifunctional protein deficiency.The mechanism of this condition indicates that the mitochondrial trifunction protein  catalyzes 3 steps in mitochondrial beta-oxidation of fatty acids: long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), long-chain enoyl-CoA hydratase, and long-chain thiolase activities. Trifunctional protein deficiency is characterized by decreased activity of all 3 enzymes. Clinically, trifunctional protein deficiency usually results in sudden unexplained infant death, cardiomyopathy, or skeletal myopathy. Diagnosis
Diagnosis of mitochondrial trifunctional protein deficiency is often confirmed using tandem mass spectrometry. Genetic counseling is available for this condition. Additionally the following exams are available:

CBC
Urine test

Treatment
Management for mitochondrial trifunctional protein deficiency entails the following:
Avoiding factors that might precipitate condition
Glucose
Low fat/high carbohydrate nutrition
