Different Types of Anabolic Steroids (Profiles)

All anabolic steroids are forms of exogenous testosterone. However, due to modifications in chemical structure, different steroids produce different outcomes, in regards to body composition and athletic performance.

Below are the different types, or categories of anabolic steroids, used by bodybuilders:

• Bulking steroids
• Cutting steroids
• Oral steroids
• Injectable steroids

Bulking steroids are used to build exceptional amounts of muscle and strength. We see these compounds typically used in the off-season (winter period), when bodybuilders eat in a calorie surplus.

Cutting steroids are instead used for enhanced fat burning, increasing muscle definition and retaining hypertrophy (size); when in a calorie deficit. These compounds are often utilized in the final weeks leading up to a competition, or in the summer for maximum aesthetics on the beach.

In this guide, we will list the different types of bulking and cutting steroids utilized by our patients, comprehensively detailing their benefits and side effects. We will list in brackets whether they are oral or injectable steroids. 

Bulking Steroids

1. Anadrol
2. Dianabol
3. Testosterone
4. Trenbolone
5. Deca Durabolin

1. Anadrol (Oral)

Anadrol (Oxymetholone) is an oral steroid used in bulking cycles, to build large amounts of muscle size (hypertrophy).

Anadrol is also one of the most powerful compounds for enhancing strength, making it very popular among strongmen and powerlifters in our experience.

Anadrol will cause hefty weight gain, being approximately 30lbs from a cycle, due it being a ‘wet steroid’; as well as anabolic.

Thus, users can expect a remarkable increase in fat-free mass, but also a significant amount of (temporary) water retention.

We find such fluid causes a huge and smooth look to a user’s physique, with very full and puffy-looking muscles.

Any excess fluid gained on Anadrol will be flushed out when a cycle finishes and estrogen levels regulate back to normal.

Anadrol Side Effects

Anadrol may be a potent mass-building steroid; however, it’s also one of the most toxic AAS (1), based on our liver function and lipid profile tests.

Anadrol will cause notable cardiac hypertrophy (enlargement of the heart), increasing the risk of heart disease. Out of all the anabolic steroids, Anadrol is among the worst from a cardiovascular perspective, due to its negative effects on hepatic lipase in the liver; contributing to drastic fluctuations in cholesterol.

Also, Anadrol is very hepatotoxic, thus we typically record high levels of liver strain/damage in users. This can be measured on-cycle by checking AST (aspartate transaminase) and ALT (alanine aminotransferase) enzymes. When these shoot up, it is evidence of liver stress, thus regular checkups with a doctor should be taken to closely monitor these scores.

Anadrol is a DHT-derived anabolic steroid, thus it often produces androgenic effects in men. We have treated patients with benign prostatic hyperplasia (prostate enlargement), acne vulgaris and androgenic alopecia (hair loss on the scalp).

2. Dianabol (Oral)

Dianabol (Methandrostenolone) is another powerful bulking compound and the most coveted oral steroid by bodybuilders.

This is due to its exceptional muscle-building and strength-enhancing effects (similar to Anadrol), yet with slightly fewer side effects.

Dianabol is also considered a ‘wet’ steroid, due to it also causing water retention. Fluid retention accumulates differently on Dianabol compared to Anadrol, with serum testosterone being converted into estrogen (via the aromatase enzyme).

Thus, bodybuilders have the choice to use an AI (aromatase inhibitor) to inhibit estrogenic-related side effects on Dianabol, preventing: gynecomastia and water weight (2). Common AI’s used are Anastrozole and Letrozole; however, we find them to reduce estrogen at the expense of worsening blood pressure levels.

Dianabol Side Effects

Dianabol is also toxic from a cardiovascular and hepatic perspective. Dianabol raises blood pressure like all anabolic steroids, albeit to a more notable degree, due to its vast effect on water retention (making blood volume increasingly viscous).

Dianabol is also liver toxic, being a c-17 alpha-alkylated steroid, thus having to pass through the liver in order to become active.

Dianabol has a low affinity to bind with the 5α-reductase enzyme, thus reducing the conversion of testosterone into DHT (dihydrotestosterone). Thus, androgenic effects are mild, thus our patients typically finish a Dianabol cycle unscathed; in relation to oily skin, acne vulgaris and prostate enlargement.

3. Testosterone (Injectable)

We find that Testosterone is usually the first steroid a bodybuilder will take, due to its mild nature and safety (in terms of side effects).

Despite not being the most ‘powerful’ anabolic steroid, we still see Testosterone producing impressive gains in size and strength.

Testosterone is predominantly administered via intramuscular injection; however, it is also available as an oral (known as Testosterone Undecanoate).

Bodybuilders generally opt for the injectable form, with it being considerably cheaper and more potent than oral Testosterone.

Testosterone is less anabolic than Dianabol, yet more androgenic. In practice, we see testosterone resulting in slightly less weight gain than Dianabol — but will build a similar amount of lean muscle tissue. The other main difference is Testosterone has a stronger reaction with the 5α-reductase enzyme, resulting in heightened levels of DHT (3).

Testosterone Side Effects

Thus, male pattern baldness, acne vulgaris and prostate issues are more likely to develop.

Despite Testosterone’s potent anabolic (muscle-building) effects, it can also be taken as a cutting steroid. This is due to Testosterone simultaneously burning fat, due to its androgenicity causing adipose tissue atrophy.

Androgen receptors are present in fat cells and thus when stimulated, lipolysis increases (4).

Testosterone is the most cardiovascular-friendly anabolic steroid in our experience, only causing mild increases in cholesterol scores.

A Testosterone-only cycle is often utilized by first-time steroid users, ranging from dosages between 200-350mg per week — and taken for 8 weeks.

Testosterone Enanthate or Cypionate are preferred injectable esters, due to their longer half-lives, meaning users don’t have to inject as regularly as a fast-acting ester (like Propionate or Suspension).

We see Testosterone often stacked with other bulking steroids, such as Trenbolone, Anadrol and Deca Durabolin. When utilized for cutting purposes it is commonly taken with Anavar.

Legal Dianabol Alternative

D-Bal is our #1 rated legal Dianabol product. It replicates the muscle-building and strength-enhancing effects of Dianabol, but without the unwanted side effects.

It is FDA-approved and can be purchased online without a prescription.

D-Bal is best suited for men wanting to build significant amounts of muscle; without shutting down their testosterone, straining their liver or elevating blood pressure levels.

4. Trenbolone (Injectable)

Trenbolone is arguably the most powerful steroid available to bodybuilders, causing rapid changes in body composition that take place within the first week of use.

Trenbolone builds exceptional amounts of muscle tissue, whilst simultaneously lowering body fat.

It enhances fat burning in the same way as testosterone, with its high androgenicity stimulating lipolysis, causing a reduction in fat stores.

Trenbolone’s androgen score of 500 vs testosterone’s 100, demonstrates its raw power in this regard.

Also, Trenbolone is not estrogenic (failing to aromatize), making it a dry compound and thus a very desirable cutting agent.

Trenbolone is a steroid that if someone is using, people can usually tell, due to dramatic changes in body composition, extreme muscle dryness and rapid growth in the deltoid and trapezius muscle regions. These three components combined can make a bodybuilder appear photoshopped in real life.

Trenbolone Side Effects

Trenbolone is one of the harshest anabolic steroids a bodybuilder can take, having devastating effects on a user’s health, based on our tests.

Trenbolone is not particularly hepatotoxic, due to it being an injectable instead of a C-17 alpha alkylated steroid.

However, we still see AST and ALT liver enzymes rise, due to trenbolone passing through the liver upon exit.

Trenbolone will have a drastic effect on blood lipids, causing an increase in heart hypertrophy (size); resulting in a higher chance of atherosclerosis.

Trenbolone’s inability to convert into estrogen does not do trenbolone users any favours in regards to regulating HDL cholesterol levels (exacerbating blood pressure levels).

Trenbolone’s high androgenicity is partly responsible for its impressive results; however, we have seen this cause acne vulgaris (and cystic acne) in some users.

Hair loss is likely to accelerate due to DHT levels spiraling to high levels, causing inflammation and damage to hair follicle health. Difficulty urinating may also become an issue, due to an enlarged prostate gland.

5. Deca Durabolin (Injectable)

Deca Durabolin (Nandrolone Decanoate) is an effective anabolic bulking agent.

It causes surges in protein synthesis and nitrogen uptake in the muscle cells, causing dramatic increases in muscle size/strength. However, its anabolic nature is not the equivalent of more powerful compounds, such as Anadrol, Dianabol or Trenbolone, in our experience.

Thus, Deca Durabolin is often taken as a stack and run simultaneously with other bulking steroids.

Deca Durabolin causes an extremely full, 3D look, due to high levels of intracellular water retention filling the muscle cells on-cycle.

Deca Durabolin may not be the most potent mass-building anabolic steroid; however, it is among the mildest compounds available. We find it to be well-tolerated by many users, especially in terms of cardiovascular health. Deca Durabolin also poses no threat to the liver.

Deca Durabolin Side Effects

Deca Durabolin has minimal adverse effects on vital organs; however, it can be disadvantageous in terms of sexual health, causing erectile dysfunction in some of our patients (typically when used alone).

This is due to Deca Durabolin reducing libido, via stimulation of the lactating hormone, prolactin.

We have had success with patients taking Cabergoline alongside Deca Durabolin; which essentially is a supplement to inhibit prolactin production. This enables bodybuilders to cycle Deca and maintain their sexual health.

Cutting Steroids

1. Winstrol
2. Anavar

1. Winstrol (Oral & Injectable)

Winstrol (Stanozolol), is available in various forms, although mostly taken as an oral steroid.

Winstrol promotes moderate increases in lean mass, whilst reducing fat-free mass.

Winstrol’s simultaneous anabolic (muscle-building) and fat-burning effects are similar to Trenbolone; albeit less potent.

Winstrol is generally used in cutting cycles to retain muscle, promote fat loss and create a dry/vascular appearance displaying full muscle definition.

Winstrol’s power lies in its low affinity to bind to SHBG (sex hormone-binding globulin), freeing up more active testosterone that is utilized for triggering lipolysis and increases in skeletal muscle.

The only downside that we see with Winstrol, in regards to body composition, is it can sometimes deflate the muscles, due to it lowering glycogen levels. This can be attributed to its diuretic properties, caused by a lack of aromatase enzyme; resulting in less intracellular fluid.

Winstrol Side Effects

Our liver function tests show Winstrol to be hepatotoxic, thus users often take a liver support supplement (such as TUDCA) to prevent liver enzymes rising to high levels.

Also, cycles should be kept short (6 weeks) and alcohol should be avoided for maximum hepatic protection.

Winstrol will also cause significant cardiovascular strain, due to substantial increases in LDL cholesterol/decreases in HDL. In some users we see this causing a flushed appearance to the skin, signifying a spike in blood pressure and thus a higher body temperature.

Winstrol can also be troublesome for the joints, due to its drying-out effects, providing less cushion and lubrication. Thus, Winstrol may not be a suitable steroid for aged bodybuilders who regularly lift heavy weights, as our older patients have reported aches or severe pain following Winstrol cycles.

Winstrol often causes virilization (masculine) effects to occur in women when taken in moderate dosages; thus we do not consider it a female-friendly steroid. However, if very small dosages are consumed (5mg per day), side effects can be kept at bay.

2. Anavar (Oral)

Anavar (Oxandrolone) is a very popular anabolic steroid among men and women. Despite its high market price, it is often coveted due to its versatility.

It can be taken by beginners as a mild steroid that increases muscle-building, without causing notable side effects.

Anavar can also be utilized by experienced steroid-users when cutting to maximize fat loss, whilst retaining muscle tissue.

We have seen women take Anavar safely without developing virilization symptoms. Thus, it has many benefits that are advantageous for both sexes.

Anavar only produces moderate increases in lean mass, hence how it’s used for cutting. Its ability to burn subcutaneous fat is surpassed by few steroids, due to its profound effect on T3 (triiodothyronine) levels.

We have found Anavar to also be effective in reducing visceral fat, with it improving insulin sensitivity. This can also suppress appetite leading to further fat loss; by increasing the likelihood of users eating in a calorie deficit.

Anavar has diuretic properties; however, unlike Winstrol, muscles will remain looking full; as only extracellular water is flushed out (not intracellular).

We see glycogen uptake within the muscles increase on Anavar, thus causing huge pumps in the gym and exceptional muscle thickness in a relaxed state.

Anavar Side Effects

Despite being a C-17 alpha alkylated steroid, Anavar does not have a drastic effect on liver enzymes. This is most likely due to it being a mild compound and the kidneys processing part of the compound (in conjunction with the liver).

Thus, it is rare that we see liver health excessively deteriorate unless taking excessive cycles or mega dosages; however, ALT/AST enzymes should be monitored regularly as a precaution.

Anavar will not cause gynecomastia, as it does not aromatize (inhibiting the conversion of testosterone into estrogen).

Anavar will have a negative effect on cholesterol, causing a mild to moderate increase in blood pressure. However, we find this adverse effect to be significantly less troublesome compared the cardiotoxicity of other anabolic steroids.
