Clenbuterol + T3 + Yohimbine
CYT3 — Clenbuterol, Liothyronine and Yohimbine Fat Loss Stack by Dragon Pharma
CYT3 is Dragon Pharma's advanced three-component fat loss formulation combining Clenbuterol, Liothyronine (T3) and Yohimbine in a single 37mcg tablet — three compounds that target fat loss through three entirely different biological mechanisms simultaneously. Supplied in a 100-tablet pack, CYT3 is designed for experienced users who have already used each component individually and understand the demands of each.

Why This Specific Combination — Three Pathways Simultaneously
The rationale for combining Clenbuterol, T3 and Yohimbine is mechanistic — each compound targets a different fat loss pathway that the others cannot access:
| Compound | Receptor/Pathway | Mechanism | Unique Contribution |
|---|---|---|---|
| Clenbuterol | Beta-2 adrenergic receptors (β2-AR) | Thermogenesis via mitochondrial uncoupling; lipolysis via HSL activation; anti-catabolic via mTOR | Directly stimulates fat cell breakdown; also preserves lean mass during caloric deficit |
| Liothyronine (T3) | Thyroid hormone receptors (TRα, TRβ) | Increases BMR by upregulating metabolic gene expression across all tissues; accelerates nutrient turnover | Systemic metabolic acceleration that Clenbuterol and Yohimbine cannot replicate — the most powerful BMR elevator of the three |
| Yohimbine | Alpha-2 adrenergic receptors (α2-AR) | Blocks α2-AR — the receptor that inhibits fat release from stubborn fat areas (lower abdomen, hips, thighs) | The only component that specifically targets alpha-2 receptor-dense "stubborn fat" depots |
The Clenbuterol + Yohimbine Synergy — Why Alpha and Beta Matter Together
This synergy is rarely explained in competitor content and represents a genuine information gap:
- Fat cells contain both beta-2 adrenergic receptors (β2-AR) which promote lipolysis when activated, and alpha-2 adrenergic receptors (α2-AR) which inhibit lipolysis when activated
- Clenbuterol activates β2-AR — pushing the fat cell toward releasing stored fat. However, in alpha-2 receptor-dense "stubborn fat" areas (typically lower abdomen in men, hips and thighs in women), the inhibitory α2-AR signal partially counteracts the β2-AR stimulation from Clenbuterol
- Yohimbine blocks α2-AR — removing this inhibitory brake. When Yohimbine blocks α2-AR simultaneously with Clenbuterol activating β2-AR, there is no competing inhibitory signal in stubborn fat depots
- The combination produces a more complete lipolytic signal in stubborn areas than either compound alone — Clenbuterol accelerates, Yohimbine removes the brake
T3's Role — Why It Is the Most Powerful but Most Demanding Component
Liothyronine (T3) is synthetic triiodothyronine — the active thyroid hormone. Its inclusion in CYT3 is the element most requiring caution:
- T3 increases basal metabolic rate more significantly than either Clenbuterol or Yohimbine — by upregulating metabolic gene expression directly in cells across all tissues simultaneously
- Unlike Clenbuterol which downregulates its receptors over 2 weeks, T3's metabolic effects do not display the same receptor downregulation — making it effective throughout a cycle
- However, T3 is not selective for fat tissue — it accelerates catabolism of all energy substrates including muscle protein. Without adequate AAS support or high protein intake, T3 at high doses can cause significant lean mass loss alongside fat loss
- T3 also suppresses natural thyroid hormone production (TSH/T4) during use — natural thyroid function takes time to recover after stopping, requiring gradual tapering rather than abrupt cessation
Fixed-Ratio Blend vs Standalone — The Advanced User Consideration
CYT3's fixed-ratio tablet format is its key practical advantage and limitation simultaneously:
- Advantage: Convenience — one tablet delivers all three compounds without managing three separate products, dosing schedules and logistics
- Limitation: The ratio of Clenbuterol to T3 to Yohimbine is fixed at the manufacturer's chosen proportion. Advanced users who want to run Clenbuterol at a higher dose relative to T3, or who want to cycle Clenbuterol on/off (2 weeks on/off) independently from T3, cannot do so with a fixed-ratio tablet
- For users new to all three compounds or wanting a straightforward starting point, CYT3's pre-combined format is the most accessible option. Advanced users who have dialled in individual doses of each compound may prefer standalone products: Clenbuterol 40mcg, T3, standalone Yohimbine
Effects and Benefits
- Three-pathway fat loss — thermogenic (Clenbuterol), metabolic acceleration (T3) and stubborn fat α2-AR blockade (Yohimbine) simultaneously
- Anti-catabolic lean mass preservation from Clenbuterol's beta-2 muscle receptor activity
- Enhanced energy and training capacity from the combined sympathomimetic stimulation
- Convenient single-tablet format covering all three compounds
- No suppression of natural testosterone — does not affect the HPG axis (T3 affects thyroid axis only)
