How to Read This Reference

The tables below compare compounds across standardised parameters to support informed decisions. A few definitional notes before diving in:

Anabolic:Androgenic (A:A) ratio is a relative scale derived from rat bioassay models comparing anabolic (tissue-building) activity to androgenic (masculinising, DHT-related) activity, with testosterone set at 100:100. These ratios are directionally useful but should not be over-interpreted, they are animal-model approximations and do not fully translate to human pharmacology. A compound with a high anabolic ratio is not simply “safer” than one with a lower ratio.

Aromatization indicates the degree to which a compound converts to estradiol via the aromatase enzyme. High aromatizers produce water retention, gynecomastia risk, and estrogen-related effects; non-aromatizers avoid these but also lose oestrogen’s cardioprotective lipid benefits.

Progestogenic activity indicates affinity for progesterone receptors. Relevant to prolactin-mediated gynecomastia and sexual side effects in 19-nor compounds (Nandrolone, Trenbolone).

Wet vs. dry is a practical colloquial classification. Wet compounds aromatize significantly or have progestogenic activity, causing water retention and a fuller appearance with higher gynecomastia risk. Dry compounds have minimal to no aromatization, produce little water retention, and create a harder, more defined appearance.

Oral Compound Hepatotoxicity Grading

Grade Description Compounds
Extreme Expected severe enzyme elevation; peliosis hepatis, hepatic adenoma, cholestasis documented Halotestin, Anadrol at high dose
Very High Consistent significant elevation; risk of cholestatic jaundice; never stack with other hepatotoxins Anadrol, Superdrol
High Significant elevation expected; TUDCA mandatory; cycle duration strictly limited Dianabol, Winstrol
Moderate-High Clinically meaningful hepatic impact; TUDCA recommended; careful duration management Winstrol, Epistane, Turinabol
Moderate Elevation common at higher doses; manageable with support and duration limits Anavar at doses >60 mg/day
Low Minimal hepatic impact at typical doses; TUDCA still sensible Anavar at 20–40 mg/day, Mesterolone

Note: TUDCA 250–500 mg/day alongside any 17-alpha-alkylated oral compound reduces hepatocellular stress and has genuine clinical evidence for reducing compound-induced enzyme elevation and hepatocyte apoptosis.


Wet vs. Dry: Practical Implications

Wet Compounds

Testosterone, Dianabol, Anadrol, Nandrolone, Equipoise, Trestolone.

Implications: Water retention creates temporary scale weight increases that mislead progress assessment. Estradiol management via AI is usually required to prevent gynecomastia. The water retained on cycle is lost post-cycle, making apparent on-cycle scale gains partially non-permanent. Cardiovascular strain from plasma volume expansion adds to cardiac workload.

Dry Compounds

Trenbolone, Masteron, Primo, Anavar, Winstrol, Turinabol, Halotestin, Superdrol.

Implications: Gains retained post-cycle are predominantly actual lean tissue rather than water. No AI required for oestrogen management. However, the absence of oestrogen’s cardioprotective effects can be a negative, very low-oestrogen environments (heavy Trenbolone with aggressive AI use) may accelerate atherogenesis. Joint pain and connective tissue dryness is a common complaint with certain dry compounds (Winstrol in particular).


Experience Level Guidelines

Beginner (First 1–2 Cycles)

Appropriate: Testosterone Enanthate or Cypionate as the sole compound is the universal recommendation. Anavar as an optional oral addition at conservative doses (20–40 mg/day) for those specifically pursuing lean gains. Female beginners may use Anavar as a sole compound.

Rationale: First cycles establish baseline response to exogenous androgens and produce the most gains available from the simplest protocol. The majority of first-cycle gains come from enhanced protein synthesis and nitrogen retention at any testosterone dose above natural levels. Adding complexity before understanding individual testosterone response is poor risk management.

Intermediate (3–5 Cycles, Reliable Bloodwork History)

Appropriate additions: Nandrolone (at doses lower than testosterone, with prolactin monitoring); Equipoise (accounting for slow saturation timeline); Masteron or Primo for leaning phases; oral kickstarts, Dianabol (4–6 weeks, liver support mandatory); oral finishers, Anavar, Turinabol, Winstrol (with liver support and bloodwork).

Advanced (Extensive Cycle History, Comprehensive Bloodwork, Medical Support)

Considered only with full awareness of compound-specific risks:

  • Trenbolone, highest harm floor of any common injectable; requires established bloodwork baseline and awareness of neurological and cardiovascular signals; Acetate ester strongly preferred over Enanthate for rapid clearance if side effects emerge
  • Halotestin, extreme hepatotoxicity; sole use case is acute strength; maximum 4 weeks at lowest effective dose
  • Superdrol, very high toxicity, severe lipid impact; only in users with well-monitored liver and cardiovascular health
  • Trestolone, research compound with limited human data; extremely potent aromatization requires heavy AI use and careful monitoring

Every additional compound multiplies interaction surface area, suppression depth, side effect management complexity, and bloodwork interpretation difficulty. Simplicity is efficiency.
