For best results, 7,3-ANDRO should be used as part of a structured Andro cycle and followed with proper post-cycle support. Choose your stack based on your goal, experience level, and training phase.
7,3-ANDRO is Steel’s recomp, cutting, and hardening-focused Andro, built for experienced lifters who want definition, density, lean performance, and a sharper physique during disciplined cutting or recomposition phases. Powered by a multi-active formula featuring 100 mg of 3-hydroxy-androstane-17-one, 25 mg of 7a-hydroxy-dehydroepiandrosterone, and 50 mg of 6-keto diosgenin per tablet, 7,3-ANDRO delivers 200 mg, 50 mg, and 100 mg of these actives daily when used as directed.
This is not a watery mass product. 7,3-ANDRO is built for the leaner, tighter, more defined side of the Steel Andro system. Where 1-ANDRO is the lean-mass foundation, 4-ANDRO supports fullness and drive, and 3-EPI-ANDRO sharpens the dry hardening lane, 7,3-ANDRO is built for users chasing recomposition, cutting support, definition, and a harder look while keeping performance in focus.

7,3-ANDRO is built for users who want more than size alone. Its role in the Steel lineup is to support the cutting, recomp, and definition side of a structured Andro cycle. This is the Andro you reach for when the goal is to tighten up, look harder, support lean performance, and bring out a sharper physique.
Where 4-ANDRO is built more for fullness and drive, and 19-NOR-ANDRO is built more for strength, mass, recovery, and joint-comfort support, 7,3-ANDRO is built for the leaner visual outcome: definition, hardness, body-composition support, and a more dialed-in look.
7,3-ANDRO is designed for experienced lifters who understand structured cycle-based supplementation and want a more serious option for cutting, recomposition, and hardening-focused phases. It is best suited for users focused on definition, density, lean performance, and a tighter look.
If your goal is maximum fullness, size, and heavy mass-focused training, 4-ANDRO or 19-NOR-ANDRO may be a better primary fit. If your goal is to look leaner, harder, tighter, and more defined, 7,3-ANDRO belongs in the center of the conversation.
Every Steel Andro is built with liposomal delivery technology to help support absorption and ingredient uptake. By pairing active Andro compounds with lipid-based carriers, this delivery system is designed to improve efficiency compared to standard oral formulas.
For 7,3-ANDRO, that means each tablet delivers a multi-active Andro formula in a format built for serious users who care about consistency, precision, and performance-focused formulation.

For full stack planning, view the complete Steel Andro Guide.
Because 7,3-ANDRO is designed for structured cycle-based use, Steel recommends following your cycle with proper post-cycle support. Alpha-AF is Steel’s PCT and natural testosterone support formula, built with key minerals, hormone-support ingredients, and absorption support to help users transition after an Andro cycle.
For best results, use 7,3-ANDRO as part of a structured Andro cycle and follow with Alpha-AF as post-cycle support.
Alpha-AF may also be used by experienced users seeking additional hormone-support and mineral support during or after a cycle, but it is most commonly positioned as the post-cycle support product in the Steel system.
If you are building a full Andro cycle, Alpha-AF should be considered part of the complete plan, not an afterthought.
ADABOLIC can be used alongside structured Andro cycles by users looking to support training output, pumps, recovery, hydration, and performance during demanding training blocks.
Best paired with: Cutting, recomp, hardening, and strength-focused Andro stacks where training performance, pump, hydration, and recovery support are priorities.
N.O.7 can be used as a non-stimulant pre-workout support product during hardening, cutting, and beach-body focused stacks. It is best positioned for users looking to support pumps and training performance without adding stimulant load.
Best paired with: Beach-body, cutting, and recomp stacks where pump and training output are important.
SHREDDED-AF is best suited for users in a disciplined cutting phase who want additional fat-loss and energy support. It should be used responsibly and should not be stacked with unnecessary stimulant load.
Best paired with: Cutting and shred-focused stacks where the user is already controlling calories, training consistently, and managing stimulant intake.
HYPERBOLIC is best suited for users in a calorie-supported growth phase. Because 7,3-ANDRO is primarily a recomp, cutting, and hardening-focused Andro, HYPERBOLIC is not the primary support product for this page, but it may be useful for users trying to maintain calories and recovery during a lean-mass or recomp phase.
Best paired with: Lean-mass or recomp cycles where the user needs additional calorie and nutrition support.
Steel Andros are built for structured, goal-specific cycles. To get the most out of your cycle, support the process with disciplined training, nutrition, hydration, sleep, and post-cycle support.
During use, we recommend avoiding alcohol and unnecessary stressors that can work against recovery, hydration, sleep quality, liver health, hormone balance, and training performance. Users should not exceed the recommended daily use and should avoid combining multiple hormone-pathway products unless they are experienced and understand structured cycle-based supplementation.
For best results, pair your Andro cycle with consistent protein intake, goal-appropriate calories, progressive training, adequate rest, and proper post-cycle support with Alpha-AF.
For cutting or recomposition: Use a controlled calorie deficit or maintenance
intake, keep protein high, and avoid crash dieting. The goal is to support performance while leaning out, not
destroy recovery.
For hardening-focused phases: Keep nutrition clean, protein consistent,
hydration high, and carbohydrates placed strategically around training. A dry, hard look is built through
training, diet, consistency, and the right stack structure.
For lean mass retention: Do not crash calories too aggressively. 7,3-ANDRO is
best used in a disciplined plan where the goal is to look leaner and more defined while keeping training
performance intact.
For best results during an Andro cycle:
Advanced Stack Notice: More is not always better. Advanced stacks are intended for experienced users only. If you are new to Andros, start with a simpler cycle before combining multiple products. Users should choose a stack based on their goal, experience level, training status, and tolerance. Do not exceed recommended use.
Important Use Notice: Not for use by individuals under 18. Do not use if pregnant, nursing, or trying to become pregnant. Consult a qualified healthcare professional before use if you have or have had liver, kidney, cardiovascular, blood pressure, endocrine, prostate, cholesterol, or other medical concerns, or if you take prescription medications. Discontinue use and consult a healthcare professional if you experience adverse reactions.
Important Cycle Note: For maximum results, this product is designed to be used as part of a structured Andro cycle and followed with proper post-cycle support. Individual results may vary based on training, nutrition, consistency, experience level, and overall cycle structure.
Steel Andros are not casual daily wellness products. They are advanced performance supplements for experienced users who respect the process: train hard, eat with purpose, recover intelligently, avoid alcohol during use, and follow the cycle with proper post-cycle support.
For best results, 7,3-ANDRO should be used as part of a structured Andro cycle and followed with proper post-cycle support. Choose your stack based on your goal, experience level, and training phase.
