Aesthetic Lean Bulk SARM Stack
Risk: Moderate-HighThe mid-tier SARM physique cycle — RAD-140 drives mass and aggression, LGD-4033 adds density and strength, MK-677 supports recovery, sleep, and connective tissue, with on-cycle enclomiphene to maintain HPTA function and TUDCA for liver protection throughout. Full PCT with both SERMs to fully restart.
Composition: 2 SARMs & Research Anabolics · 1 Supplement · 1 Ancillary / PCT · 1 GH & IGF
Overview
The Aesthetic Lean Bulk SARM Stack is built for users ready to chase serious, visible lean mass and density without jumping to full AAS. RAD-140 and LGD-4033 together deliver a punchy anabolic environment—RAD brings the fullness and aggression, LGD locks in density and reliable tissue gain—with MK-677 supporting deeper sleep, recovery, and tissue remodeling. On-cycle enclomiphene helps keep the HPTA from crashing entirely. TUDCA runs alongside the cycle and covers the liver angle. Full PCT on the backend with enclomiphene locks down recovery, so you bounce back hard and don't lose your gains or tank your mood.
This isn't a "dabble with SARMs" protocol—it's a serious intermediate cycle for physique-focused users who want measurable progression, not a two-pound memory from microdosed ostarine. If you're ready for a defined, noticeable upgrade with manageable sides and a pro-level protocol, this stack delivers. Not for complete beginners or anyone half-in on support and recovery.
Why this stack works
- RAD-140 is the core mass builder, chosen for its high anabolic-to-androgenic ratio, significant fullness, and uniquely high ceiling among SARMs. It's less harsh on hair than test/other DHT derivatives, making it a good fit for looksmaxxers with hair preservation in mind.
- LGD-4033 synergizes well with RAD—it's slightly less aggressive but adds density, reliable lean mass, and strength punch. The two together bring a more complete, "round" look than either solo.
- MK-677 brings the GH/IGF-1 angle—better deep sleep, improved connective tissue, faster recovery. It makes the most of the anabolic window, especially on a calorie surplus, and helps skin, hair, and nails. Also solidifies joint and tendon recovery which many miss on bulk cycles.
- Enclomiphene runs concurrently so the HPTA isn't completely bottomed out. It's the SERM with the best mood and sexual function profile and preserves LH/FSH to keep endogenous test ticking.
- TUDCA is here for bulletproof cycle support—specifically for RAD-140's hepatotoxicity risk and the general stress of moderate/high-dose oral SARMs. You get actual protection that isn't just milk thistle placebo.
- PCT enclomiphene restarts your axis once suppressive SARMs are dropped, locking in gains and stabilizing your mood, libido, and energy. No point bulking hard and then flat-lining for two months post-cycle.

| Week | Compound | Dose | Frequency | Notes |
|---|---|---|---|---|
| 1-8 | RAD-140 | 15 mg | AM daily | Take with food for best GI tolerance |
| 1-8 | LGD-4033 | 10 mg | AM daily | Can be co-dosed with RAD-140 |
| 1-8 | MK-677 | 25 mg | PM daily | Dose ~1 hour before bed to maximize sleep quality |
| 1-8 | Enclomiphene | 12.5 mg | AM daily | Supports LH/FSH during suppression |
Protocol notes: Where possible, maintain consistent dosing times for SARMs and MK-677. If experiencing appetite overshoot or excessive water retention from MK-677, consider intermittent fasting window or short breaks—but continuous use is optimal here.
- MK-677: Expect increased hunger and transient water retention. If glucose or HbA1c drift up, berberine or low-dose metformin can help manage insulin sensitivity.
- SARMs: Bloodwork at week 5–6 to check liver enzymes (ALT, AST), lipids, and total/free test. If liver enzymes climb 3x baseline, consider lowering RAD-140 or pausing cycle.
- Enclomiphene: Run a zinc and vitamin D3 baseline prior to ensure full effect and minimize mood/energy drop-offs.
- Joint/connective support: Collagen + vitamin C + glycine stack supports MK-677's connective-tissue boost.
- Lipids: Omega-3 (3+ g EPA/DHA), low-sat-fat diet to buffer SARM-driven HDL drops.
| Week | Compound | Dose | Frequency | Notes |
|---|---|---|---|---|
| 1-12 | TUDCA | 500 mg | AM & PM | Split 250 mg with breakfast / dinner for GI comfort |
TUDCA starts on day one and continues past the cycle into PCT, giving a buffer for liver regeneration and recovery.
- TUDCA: Always take at least 45–60 minutes away from SARMs for maximum absorption—TUDCA can interfere with oral bioavailability of androgens if taken together.
- Avoid mega-dose NAC or silymarin during-cycle (may compete for the same ER stress pathways—TUDCA is the primary liver tool here).
- Monitor for loose stools; if problematic, reduce to 250 mg twice daily and ramp back up after adapting.
| Week | Compound | Dose | Frequency | Notes |
|---|---|---|---|---|
| 9-12 | Enclomiphene | 12.5 mg | AM daily | Run full 4 weeks post-cycle for robust restart |
Begin PCT immediately after last dose of SARMs. No overlap, just drop suppressive SARMs and continue enclomiphene at the same dose.
- Enclomiphene: Watch for mood, vision changes, or low libido—rare, but adjust if severe. Consider abstaining from heavy alcohol until full hormonal normalization (liver and axis both are recovering).
- Bloodwork: Test total testosterone, LH/FSH at week 12 to confirm recovery. Don't resume suppressive agents until labs normal.
