Although studies have evaluated the ecotoxicity and fate of trenbolone acetate (TBA) metabolites, namely 17α-trenbolone (17α-TBOH), 17β-trenbolone (17β-TBOH), and trendione (TBO), their environmental transport processes remain poorly characterized with little information available to guide agricultural runoff management.

Abstract:

Trenbolone acetate (TBA) is a hormone being permitted to be used as growth promoters for livestocks in several meat-exporting countries. The presence of trenbolone residu in animal products might affect human health. The purpose of this study was to determine the distribution of trenbolone residue (TBA dan 17 ÃŸ-trenbolone) in tissues and urine of Onggole male calves. The implantation of 200 mg TBA as Finaplix-HÂ® was done subcutaneously on the back side of the medial part of ear. Urine were collected periodically until 21 days post implantation.

Abstract:

The effect of various doses of trenbolone acetate, either atone or in combination with oestradiol-17G, on liveweight loss of steers fed restricted amounts of low-quality roughage was determined in a series of experiments. It was found that for steers of 350-400 kg liveweight, a dose of at least 300 mg trenbolone acetate had to be used for significant reduction of the rate of weight loss. Treatment with 300 and 400 mg trenbolone acetate significantly (P < 0.01) reduced concentrations of plasma urea-N.

Despite the European ban of using anabolics in food-producing animals, growth promoters might still be illegally used in the European Union. To control the food chain and guarantee consumers’ health, there is a need of highly sensitive analytical methods for the identification of marker residues of such treatments. In the present study, a group of bulls (n=16) received trenbolone acetate (200 mg) and estradiol (40 mg) by a commercial ear implant during a time range of 71 days, and a second group (n=16) was kept for control.

Abstract:

In seasonally dry areas cattle undergo periods of arrested growth because the forage on offer is of poor quality. Annual liveweight gains could be increased and age of turnoff for slaughter reduced if maintenance energy requirements could be lowered during the dry season with no concomitant reduction in forage intake. Strategies to reduce metabolic rate, and so rate of liveweight loss using the anabolic steroid, trenbolone acetate, and the �2-agonist, guanfacin, are discussed. Both compounds reduced fasting metabolic rate of steers; an implant of 300 mg trenbolone acetate by about 10% and cont

Abstract Trenbolone acetate is a synthetic testosterone analog registered for use in a number of countries as a growth-promoting hormone, applied as an implant in the ears of feedlot cattle. The method is intended for the detection and quantitation of trace amounts of α- and β-trenbolone in bovine tissues (muscle, liver) by liquid chromatography (LC) with UV detection and eliminates the use of the structural analog, 19-nortestosterone, as an internal standard.

However, little is known of the effects of anabolic steroid hormone administration on wool growth.

Abstract:

Case: A 33-year-old male presented to the emergency department with complaints of polydipsia, polyuria, nausea, headaches, blurry vision and malaise. Lab work revealed a serum glucose level of 1166 mg/dl (64.8 mmol/L). The patient admitted to completing a cycle of androgenic anabolic steroids (AASs) for bodybuilding. His regimen consisted of supraphysiologic intramuscular injections of a bovine growth hormone, trenbolone acetate and testosterone. The patient received intravenous fluids and insulin to restore metabolic balance. Previously healthy with a non-contributory family history, he was d

AbstractThirty-two Border Leicester ♂ × Scottish Blackface ♀ wether lambs aged about 5 months were divided into two groups on the basis of live weight such that group Gl contained the 16 lightest lambs and group G2 the 16 heaviest. Lambs in group Gl were subdivided equally at random either to be sham-implanted controls (group C1) or to be implanted with 35 mg trenbolone acetate (TBA) + 5 mg oestradiol-17β (group T1) at 24 kg initial live weight. The lambs in group G2 were also subdivided into two groups (groups C2 and T2) and similarly treated approximately 1 month later at 37 kg initial live

ABSTRACTThe effects of recombinantly derived growth hormone (GH), oestradiol-17β plus trenbolone acetate, clofibrate, melatonin and fasting on basal plasma triglycerides (TG) and TG entry rate were determined in wether lambs given lucerene/barley pellets ad libitum. Clofibrate was administered at 2 × 0·5 g capsules orally, GH (0·25 mg/kg live weight) was injected subcutaneously daily whilst oestradiol-17β, oestradiol-17β plus trenbolone acetate and melatonin were slow release implants (either 4 or 4·8 mg, 4 nig and 20 nig and 18 mg respectively) placed subcutaneously in the ear.

Abstract:

A computational model of oocyte growth dynamics (i.e., oocyte recruitment, growth, and spawning) in a batch-spawning fish, fathead minnow (FHM, Pimephales promelas), has been developed. The model provides a quantitative link between oocyte growth dynamics and biochemical processes in FHMs through the absorption of vitellogenin (a lipoprotein precursor of egg yolk proteins) into oocytes, which contributes significantly to oocyte growth in fish. The model simulates the number and volume of oocytes in different batches within a FHM ovary. Model-predicted clutch sizes and spawning intervals matche

Abstract:

Selective androgen receptor modulators (SARMs) now under development can protect against muscle and bone loss without causing prostate growth or polycythemia. 17β-Hydroxyestra-4,9,11-trien-3-one (trenbolone), a potent testosterone analog, may have SARM-like actions because, unlike testosterone, trenbolone does not undergo tissue-specific 5α-reduction to form more potent androgens. We tested the hypothesis that trenbolone-enanthate (TREN) might prevent orchiectomy-induced losses in muscle and bone and visceral fat accumulation without increasing prostate mass or resulting in adverse hemoglobin

Abstract:

SUMMARY Plasma elimination rates of sulfamethazine (100 mg/kg of body weight, iv), trimethoprim (20 mg/kg, iv), and antipyrine (35 mg/kg, iv) were studied in adult female dwarf goats (n = 5) before and after implantation with trenbolone acetate (5 mg/kg). Pretreatment with trenbolone caused a significant decrease in the elimination rate of the drugs tested: for sulfamethazine, 5 times; for antipyrine, 3 times; and for trimethoprim, 2 times. After treatment with testosterone (1 mg/kg, SC, twice weekly for 2.5 weeks), female goats (n = 5) had a similar decrease in the elimination rate of sulfame
