Fat loss and AAS..Let's talk about it! (Is there some real truth?)

Over the years there's been massive debates, and of lately there's been some discussions in many of the panels in regards to AAS and fat loss..Some in the gear world populace are advocating that there's "no such thing", or AAS don't burn fat..

"I think we can all agree that diet dictates everything,but for arguments sake,let's talk about AAS solely and it's benefits"

So, let's discuss this... (AAS only, no stims or bata's,or GH)

Now, you're gonna hear mix reviews on this.. However, I have seen enough evidence that supports AAS having,creating a environment/platform for fat burning..DIET without a doubt is crucial, and the pivotal player..However, there is real science behind fat loss and AAS, but please don't put all your money on it soley as an effective combatant..But nonetheless AAS is effective!

AAS that are seen/recognized on the high/or moderate androgenic scale will in fact promote/increase lypolysis..Thus andros have a higher binding affinity to AR's..

FYI; Androgen receptors are found throughout cellular groups, as well as FAT and muscle cell/groups, now we know that they initiate a response on AR's in muscle cells to promote size/growth, at the same given time they will have a cascade of effects on other cells and AR's found therein fat cells inducing activity/burning..Higher/more potent the androgen binds to the androgen receptors, the greater the lipolytic response will be on adipose tissue (brown or white)...

Now lets also take into great consideration AR upregulation with the presence of androgens, more AR sites throughout targeting tissue..,There's a vast amount of activity in which a complex interplay between activation and inactivation mechanisms and signaling between cell groups, what People need to remember that hormones are "chemical messengers" that rely messages to cells that display specific receptors for each hormone and respond to the signaling..Depending on the compounds and the individuals metabolization ratio the hormone can/may make changes directly to a cell, by changing the genes that are activated, or by making changes indirectly to a cell by stimulating other signaling pathways inside a specific cell group that is effected and effect other processes, thus this can "initiate" an intracellular cascade of events.. So, the notion that fat loss is NOT presence, and to mitigate that AAS don't posses any fat loss properties is absurd...

So, yes AAS may assist with fat loss, however don't expect miracles and it's advised to have a lower body fat% by diet to expect to see more fat loss effects, but its not crucial..Have your macro's dialed in with your AAS intake, cardio ,and anything is possible, we've seen amazing things happen in this lifestyle..

There's an abundance of clinical research and peer-reviewed data that strongly supports testosterone (and other AAS) fat reducing actions and its preventative impact on adipocyte generation...As AAS (especially Testosterone) acts both in the breakdown of existing fat tissue and to hinder pre-adipocytes from maturing.

This is where some AAS began you accure theer reputation, or spin a myth (winstrol) at promoting fat loss, and achieve lower body fat,cuts..With this said, there's some truth behind winstrol and cuts, but not directly!

Share you thoughts and experience with this!

Below is some studies conducted in fat loss, one in particular stresses the relation with diet and TRT and others just on a placebo and diet...The outcome is astonishing!!

  • Androgens play an important role in regulation of body fat distribution in humans. They exert direct effects on adipocyte differentiation in a depot-specific manner, via the androgen receptor (AR), leading to modulation of adipocyte size and fat compartment expansion. Androgens also impact directly on key adipocyte functions including insulin signalling, lipid metabolism, fatty acid uptake and adipokine production. Androgen excess and deficiency have implications for metabolic health in both males and females, and these metabolic effects may be mediated through adipose tissue via effects on fat distribution, adipocyte function and lipolysis. Research into the field of androgen metabolism in human and animal adipose tissue has produced inconsistent results; it is important to take into account the sex-, depot- and organism-specific effects of androgens in fat. In general, studies point towards a stimulatory effect on lipolysis, with impairment of adipocyte differentiation, insulin signalling and adipokine generation. Observed effects are frequently gender-specific. Adipose tissue is an important organ of pre-receptor androgen metabolism, through which local androgen availability is rigorously controlled. Adipose androgen exposure is tightly controlled by isoenzymes of AKR1C, 5α-reductase and others, but regulation of the balance between generation and irreversible inactivation remains poorly understood. In particular, AKR1C2 and AKR1C3 are crucial in the regulation of local androgen bioavailability within adipose tissue. These isoforms control the balance between activation of androstenedione (A) to testosterone (T) by the 17β-hydroxysteroid dehydrogenase activity (17β-HSD) of AKR1C3, or inactivation of 5α-dihydrotestosterone (DHT) to 5α-androstane-3α,17β-diol by the 3α-hydroxysteroid dehydrogenase (3α-HSD) activity of AKR1C2. Most studies suggest that androgen inactivation is the predominant reaction in fat, particularly in the abdominal subcutaneous (SC) depot. Modulation of local adipose androgen availability may afford future therapeutic options to improve metabolic phenotype in disorders of androgen excess and deficiency.

Recent studies in men have shown that abdominal fat increases with age and decreasing testosterone concentrations. Furthermore, in cell culture, testosterone expresses an increased lipolytic potential and depresses lipoprotein lipase activity (LPL) in adipose cells. These metabolic characteristics are found in abdominal adipose tissue in young men. In order to see whether abdominal fat masses in moderately obese middle-aged men might be diminished by testosterone, this hormone was given either as a single injection (500 mg) or in moderate doses (40 mg X 4) for 6 weeks in an oral preparation, bypassing the liver. When measured 1 week after the single dose, abdominal LPL tended to decrease. After 6 weeks a dramatic decrease of abdominal LPL was found, as well as an increase in the lipolytic responsiveness to norepinephrine, both changes confined solely to the abdominal, and not femoral adipose tissue regions. The waist/hip circumference decreased in 9 out of the 11 examined men. No untoward effects were seen in behavioural variables, blood pressure, triglyceride or cholesterol values, and liver function tests. These preliminary results suggest that administration of testosterone in moderate doses to middle-aged men lead to adaptations of the metabolism of adipose tissue expected to be followed by a diminution of this mass.


Testosterone Treatment Combined With Diet Reduces Fat, Maintains Muscle
April 5, 2016

By Frances Morin

BOSTON -- April 5, 2016 -- Obese men treated with testosterone in addition to a low-calorie diet show greater reduction in body fat and less loss of muscle mass than men on similar diets who did not receive testosterone, according to a study presented here at the 98th Annual Meeting of the Endocrine Society (ENDO).
"In men successfully losing weight through diet, both lean and fat mass are lost," said Mark Ng Tang Fui, MBBS, BMedSc, The University of Melbourne, Heidelberg, Australia, on April 3.
"The addition of testosterone prevents the loss of lean mass and shifts weight loss to almost exclusive loss of fat," he added.
Obesity has been linked to lower testosterone levels, whereas weight loss resulting from calorie restriction is linked to increases in circulating testosterone, noted the researchers. At the same time, weight loss in middle-aged men typically depletes fat and muscle.
Although testosterone treatment has been also shown to reduce fat mass, the effects of combining testosterone treatment with calorie restriction have not been demonstrated.
For the study, the researchers enrolled 100 obese men (body mass index [BMI], >30 kg/m2), aged 18 to 75 years, with low to low-normal serum total testosterone levels (average of 2 consecutive morning fasting levels of <12 nmol/L [<346 ng/dL]).
The men were all placed on a very-low-calorie diet (~600 kcal/day) for 10 weeks, followed by a maintenance period of 46 weeks. They were randomised 1:1 in a blinded fashion to receive intramuscular testosterone 1,000 mg or placebo injections at baseline, week 6, and every 6 weeks thereafter over the 56 weeks of the study.
At the study's end, weight loss in both groups was similar, ie, an average of 11 kg (24.2 lb; P < .05 vs baseline). However, patients in the testosterone group lost 3 kg (6.6 lb) more body fat than those in the placebo group (P = .05) and lost significantly less lean mass than those in the placebo group (P = .001).
Patients in the testosterone group also lost significantly more visceral adipose tissue at week 56 (P < .05).
"We found that testosterone treatment reduces fat mass in obese men with a low testosterone level, more than the effects of diet alone," concluded Dr. Fui. "Testosterone treatment also reduces visceral fat, more than the effects of diet alone, and prevents diet-associated loss of lean mass and muscle function."
"Although these changes are expected to be metabolically favourable, further trials in this population need to determine cardiometabolic and other benefits weighed against potential adverse effects," Dr. Fui added.

Testosterone therapy in hypogonadal men results in sustained and clinically meaningful weight loss

Hypogonadism is associated with increased fat mass and reduced muscle mass, which contributes to obesity and health risks, such as cardiovascular disease.Testosterone treatment of hypogonadal men improves muscle mass and reduces fat mass; however, many of these studies are of short duration.Thus, the long-term effects of testosterone on body anthropometry are not known.


Long-term testosterone treatment of hypogonadal men, up to 5 years duration, produced marked and significant decrease in body weight, waist circumference and body mass index. Hypogonadism contributes to reduced muscle mass and increased adiposity.Testosterone treatment ameliorates loss of muscle mass and reduces fat accumulation associated with hypogonadism. In this study, we evaluated the long-term effects of normalizing testosterone (T) levels in hypogonadal men on anthropometric parameters. Open-label, single-center, cumulative, prospective registry study of 261 men (32-84 years, mean 59.5 ± 8.4 years, with T levels ***8804;12 nmol L-1 [mean: 7.7 ± 2.1]). Among the 261 men on T treatment, we followed up on 260 men for at least 2 years, 237 for 3 years, 195 for 4 years and 163 for at least 5 years. Subjects received parenteral T undecanoate 1000 mg every 12 weeks after an initial interval of 6 weeks. Body weight (BW), waist circumference (WC) and body mass index (BMI) were measured at baseline and yearly after treatment with T. BW decreased from 100.1 ± 14.0 kg to 92.5 ± 11.2 kg and WC was reduced from 107.7 ± 10.0 cm to 99.0 ± 9.1 cm. BMI declined from 31.7 ± 4.4 m kg-2 to 29.4 ± 3.4 m kg-2. All parameters examined were statistically significant vs. baseline and vs. the previous year over 5 years, indicating a continuous weight loss (WL) over the full observation period. The mean per cent WL was 3.2 ± 0.3% after 1 year, 5.6 ± 0.3%, after 2 years, 7.5 ± 0.3% after 3 years, 9.1 ± 0.3% after 4 years and 10.5 ± 0.4% after 5 years. The data obtained from this uncontrolled, observational, registry study suggest that raising serum T to normal physiological levels in hypogonadal men produces consistent loss in BW, WC and BMI. These marked improvements were progressive over the 5 years of the study.
