Steroid Comparison

[ChasetheCase]

I've been researching the different compounds over the last few weeks and thought some of you may benefit from it. I'm by all means not an expect so please comment if anything should be added or removed, or any other critique and I can update.

Stanozolol (Winstrol)	320:30	★★★☆☆	High	Moderate	High	Very Negative	Low	Dry Joints, Liver Toxicity
Turinabol (Tbol)	54:6	★★★☆☆	Low	Low	Low	Negative	Low	Mild, Slow Gains, No Water Retention
Anadrol (Oxymetholone)	320:45	★★★★★+	Very High	Very High	Extreme	Very Negative	High	Extreme Water Retention, Liver Toxicity
Primobolan (Methenolone)	88:44	★★★☆☆	Mild	Mild	Mild	Neutral	Neutral	One of the safest steroids; low suppression

Explanation of Ratings:​

• Anabolic:Androgenic Ratio → Higher means more muscle-building (anabolic) and/or more androgenic side effects.
• Muscle Building → Rated from ★☆☆☆☆ to ★★★★★+ based on effectiveness for hypertrophy.
• LVH Risk (Left Ventricular Hypertrophy) → How much the steroid impacts heart muscle thickening.
• BP Impact (Blood Pressure) → Higher means more risk of hypertension and LVH.
• Cardiac Issues → How much it negatively affects heart health.
• Lipids Effect → Negative means it reduces HDL (good cholesterol) and increases LDL (bad cholesterol).
• HCT Increase (Hematocrit) → Higher means more red blood cell production, increasing blood thickness.
• Other Side Effects → Includes estrogenic, androgenic, or unique issues.

Curious about npp/deca muscle building capabilities.

Pharmacokinetic Parameters for Inclusion​

Half-Life Data​

Compound	Half-Life	Route-Specific Considerations
Testosterone Enanthate	4-5 days	Requires intramuscular injection
Testosterone Propionate	2-3 days	Requires more frequent injections than enanthate ester
Testosterone Cypionate	5-8 days	Similar to enanthate but with slightly longer duration
Nandrolone Phenylpropionate	2-3 days	Shorter than decanoate ester
Deca Durabolin (Nandrolone Decanoate)	6-12 days	Longest half-life among nandrolone esters
Boldenone (Equipoise)	10-14 days	Prolonged detection window
Masteron Propionate	2-3 days	Requires frequent administration
Masteron Enanthate	4-5 days	Less frequent administration than propionate
Trenbolone Acetate	1-2 days	Necessitates daily or alternate-day administration
Trenbolone Enanthate	5-7 days	Weekly administration possible
Winstrol (Stanozolol)	8-24 hours (oral) / 1-2 days (injectable)	Dual administration routes with distinct kinetics
Sustanon 250	Biphasic: 1-3 days (propionate) and 15-18 days (decanoate)	Blend designed for sustained release
Dianabol (Methandrostenolone)	3-6 hours	Requires multiple daily dosing
Anavar (Oxandrolone)	9-10 hours	Typically administered twice daily
Turinabol (Tbol)	16-24 hours	Once daily administration possible
Anadrol (Oxymetholone)	8-10 hours	Short half-life despite powerful effects

Oral Bioavailability and First-Pass Metabolism​

Compound	Oral Bioavailability	First-Pass Hepatic Considerations	17α-Alkylation Status
Testosterone (unmodified)	<5%	Extensive first-pass inactivation	No
Dianabol (Methandrostenolone)	30-50%	17α-alkylated to resist first-pass metabolism	Yes
Winstrol (Stanozolol)	50-60%	17α-alkylated; significant hepatic strain	Yes
Anavar (Oxandrolone)	~97%	17α-alkylated but less hepatotoxic than other orals	Yes
Turinabol (Tbol)	40-60%	17α-alkylated with moderate hepatotoxicity	Yes
Anadrol (Oxymetholone)	~50%	Highly 17α-alkylated with pronounced hepatotoxicity	Yes

Note: Injectable compounds bypass significant first-pass metabolism but may still exert hepatotoxic effects via systemic circulation, particularly 17α-alkylated derivatives.

Clinical Monitoring Parameters​

Recommended Monitoring Schedule for Healthcare Professionals​

Parameter	Baseline	During Administration	Post-Cycle	Clinical Significance
Complete Blood Count	✓	Every 4-6 weeks	4-6 weeks after discontinuation	Monitors polycythemia risk, particularly with testosterone derivatives
Comprehensive Metabolic Panel	✓	Every 2-4 weeks for orals; Every 4-6 weeks for injectables	4-6 weeks after discontinuation	Assesses hepatic function (AST, ALT, bilirubin) and renal function
Lipid Profile	✓	Every 4-8 weeks	8-12 weeks after discontinuation	Monitors cardiovascular risk via HDL suppression and LDL elevation
Blood Pressure	✓	Weekly for first month; biweekly thereafter	Biweekly until normalized	Hypertension is a common early adverse effect
Echocardiography	✓	Every 6 months for long-term use	6 months after discontinuation for high-risk compounds	Evaluates left ventricular hypertrophy and cardiac function
Hormone Panel	✓	Mid-cycle	4-8 weeks after discontinuation	Tracks endogenous hormone suppression and recovery
PSA (males >40)	✓	Every 3-6 months	3 months after discontinuation	Monitors prostatic effects in at-risk populations
Thyroid Function	✓	Every 2-3 months	2 months after discontinuation	Some AAS affect thyroid hormone binding globulin

Compound-Specific Monitoring Considerations​

Compound	Special Monitoring Parameters	Frequency	Rationale
17α-alkylated orals (Dianabol, Winstrol, Anavar, Anadrol)	GGT, ALP, and liver ultrasound	Every 2-4 weeks during administration	Higher risk of cholestatic liver injury
Trenbolone compounds	Pulmonary function, neuropsychiatric assessment	Baseline and as clinically indicated	Associated with dyspnea and neurocognitive effects
Nandrolone derivatives	Prolactin levels	Baseline and every 4 weeks	Exhibits moderate dopaminergic antagonist properties
Testosterone esters	Estradiol, DHT	Every 4-6 weeks	Identifies aromatization and 5α-reduction magnitude
All compounds	Fasting glucose, HbA1c, HOMA-IR	Baseline and every 3 months	AAS impair insulin sensitivity despite anabolic effects
