## 1. What are anabolic steroids?

Anabolic‑steroid drugs are synthetic derivatives of the male sex hormone **testosterone**. They share a similar chemical backbone but have been chemically altered to:

- **Maximize "anabolic" (muscle‑building) effects**
- **Reduce "androgenic" (male‑characteristic) side‑effects**

In short, they help you grow muscle mass faster than natural hormones alone would allow.

### 1.1 How do they work in the body?

1. **Hormone binding** – They enter cells and bind to intracellular **androgen receptors**.
2. **Gene expression** – The hormone‑receptor complex travels into the nucleus, where it activates specific genes that drive:
- Protein synthesis (muscle growth)
- Nitrogen retention
- Red blood cell production (via erythropoietin stimulation)
3. **Metabolic shifts** – They can also influence insulin sensitivity and lipolysis.

### 1.2 What happens if you stop taking them?

- The body’s own hormone levels may drop, leading to a period of reduced muscle mass and decreased strength until natural testosterone production catches up.
- Some side effects (e.g., gynecomastia) might persist temporarily due to lingering estrogenic activity.
- Hormonal rebound can trigger mood swings or fatigue.

## 2. How Do Steroids Work?

Steroids (anabolic–androgenic steroids, AAS) are synthetic derivatives of testosterone designed for:

1. **Enhanced protein synthesis** – by binding androgen receptors in muscle cells.
2. **Reduced protein breakdown** – via decreased ubiquitin‑proteasome activity.
3. **Increased red blood cell production** – improving oxygen delivery.
4. **Glucose uptake** – enhancing glycogen storage.

### Mechanisms of Action

| Target | Effect |
|--------|--------|
| Androgen receptor (nuclear) | Activates transcription of genes involved in muscle growth and nitrogen retention. |
| Estrogen receptors | In some AAS, aromatization to estradiol stimulates bone density but can cause gynecomastia if excess. |
| Prolactin secretion | Some AAS increase prolactin → galactorrhea; high levels inhibit LH/FSH. |
| GHRH (growth hormone releasing hormone) | Indirectly raises GH and IGF‑1, promoting protein synthesis. |

### Interaction with Hormonal Balance

- **Suppression of HPG axis**: Exogenous steroids suppress gonadotropin release → decreased testicular production of testosterone and sperm.
- **Compensatory mechanisms**: Elevated prolactin can further inhibit LH/FSH.
- **Side effects**: Gynecomastia, acne, hair loss, infertility.

## 4. Clinical Implications for the Patient

| Issue | Impact on this patient |
|-------|------------------------|
| **Low testosterone** | Reduced libido, fatigue, depression, decreased muscle mass and bone density. |
| **Low LH/FSH** | Indicates primary hypogonadism; HPG axis suppressed. |
| **Low prolactin** | Not a cause of symptoms but may reflect low pituitary activity. |
| **No thyroid or adrenal dysfunction** | No need to evaluate those axes. |

### 4.1 Treatment Options

| Modality | How it works | Benefits | Risks/Considerations |
|----------|--------------|----------|---------------------|
| **Testosterone Replacement Therapy (TRT)**
• Oral, transdermal gel, intramuscular injections
• Restores serum testosterone to normal levels | Improves libido, energy, mood, muscle mass, bone density | • Can suppress sperm production → infertility risk
• May increase red blood cell count (polycythemia)
• Potential cardiovascular effects (controversial) | Must monitor PSA, hematocrit, liver enzymes; contraindicated in prostate cancer |
| **Selective Androgen Receptor Modulators (SARMs)**
• Oral compounds that target muscle and bone with less hepatic metabolism
• Not yet approved for medical use | May increase lean body mass, reduce fat without liver toxicity | • Long‑term safety unknown
• Off‑label use not regulated → variable purity | No established dosing; off‑label; potential regulatory issues |
| **Growth Hormone (GH) Therapy**
• Recombinant GH injections; often used in adults with GH deficiency or for anti‑aging | Improves lean body mass, reduces visceral fat, enhances insulin sensitivity | • Requires daily injections
• Side effects: joint pain, edema, glucose intolerance, increased cancer risk | Standard dosing 0.3–1 IU/day (adjusted by IGF‑1); monitored by endocrinology |
| **Metformin**
• First‑line for type 2 diabetes; improves insulin sensitivity, reduces hepatic gluconeogenesis | Improves glycemic control, modest weight loss, potential longevity benefits | • GI upset, lactic acidosis risk in renal impairment | 500 mg BID to TID (max 2000 mg/day) |

## 4. Suggested Lifestyle / Exercise Program

| Goal | Activity | Frequency & Duration |
|------|----------|-----------------------|
| **Aerobic conditioning** | Brisk walking, cycling, swimming | ≥150 min/week moderate‑intensity or 75 min/week vigorous |
| **Resistance training** | Body‑weight exercises (push‑ups, squats, lunges) + free weights | 2–3×/week, 30–45 min/session |
| **Flexibility & balance** | Yoga or Tai Chi | 1–2×/week |
| **Daily movement** | Aim for ≥10k steps/day; use standing desk | N/A |

Track via a wearable device or phone app.
