CY3 by Dragon Pharma
What Is CY3?
CY3 from Dragon Pharma is a fixed oral combination of three actives used in cutting blocks: clenbuterol, a beta-2 agonist that raises thermogenesis; liothyronine (T3), the active thyroid hormone that supports metabolic rate; and yohimbine, an alpha-2 antagonist that is referenced for mobilizing stubborn fat stores. Each pack holds 100 tablets.
People who buy CY3 are usually in the last phase of leaning out, when diet and cardio alone stop moving the scale and they want a stronger metabolic push without losing muscle definition. Because the three compounds act through different pathways, the effect is broader than any single fat burner: more heat, a faster metabolic drive, and better access to fat stores that resist plain dieting.
CY3 is not a casual supplement. Clenbuterol and yohimbine are strong stimulants and T3 affects the whole metabolic system, so this tablet belongs in short, structured cutting phases with disciplined dosing, good hydration, and a clean diet. Dragon Pharma CY3 is built for that kind of controlled use, one measured tablet at a time.
CY3 Dosage
CY3 by Dragon Pharma is dosed from 37 mcg tablets and every tablet carries a meaningful stimulant load, so the starting rule is the same as with any clenbuterol-based product: begin small, assess heart rate and tremor, and hold the lowest amount that still does the job.
| Phase | Reference approach | Note |
|---|---|---|
| Acclimation | Half a tablet (0.5 tab) in the morning | First 2-3 days only, check tolerance |
| Build-up | 1 tablet per day, morning dose | Raise only if sides stay mild |
| Adjustment | Up to 1.5-2 tablets in split doses | Only if the previous step is fully tolerated |
| Break | Stop or taper after 3-4 weeks on-block | Give beta receptors and thyroid axis a rest |
Cycle Length
Take CY3 early in the day: clenbuterol and yohimbine can disturb sleep, and T3 works best on a consistent daily rhythm. Do not stack extra stimulants, keep caffeine to a minimum, and drink more water with electrolytes than usual. One 100-tablet pack covers several short blocks for someone who stays on a low effective dose.
CY3 Stacks
CY3 does the metabolic work on its own, so stack partners are chosen to hold muscle and add hardness rather than to push stimulants further. Every compound below is made by Dragon Pharma.
| Stack partner | Role in the stack |
|---|---|
| Primobolan 100 | Keeps lean tissue during the calorie deficit |
| Masteron 100 | Adds muscle density without water retention |
| Cypionat 250 | Low-dose test base for drive and recovery |
| Winstrol 50 | Hardens the look in the final weeks |
| Anavar 50 | Lean strength and fullness while cutting |
Do not pair CY3 with other clenbuterol, yohimbine, or caffeine-heavy products. If the goal is only metabolic support without the stimulant layer, most users simply run CY3 alone with protein kept high and cardio consistent.
CY3 Side Effects
CY3 concentrates three strong metabolic stimulants in one tablet, so the side effect list is dominated by the cardiovascular and nervous system effects of clenbuterol and yohimbine plus the metabolic effects of T3. This is a short-phase cutting product, not an everyday supplement.
- Stimulation: jitteriness, hand tremor, headache, and a racing feeling are the most reported effects, especially in the first days.
- Sleep disruption: late dosing can ruin sleep quality; keep the dose in the morning.
- Muscle cramps: clenbuterol depletes taurine and potassium; electrolytes and taurine support are standard practice.
- Metabolic effects: T3 raises calorie burn but can pull at muscle tissue when protein is too low; keep protein high and deficit moderate.
- Heart-rate tolerance: beta-2 receptor downregulation means the effect fades with continuous use, which is why breaks are part of the protocol.

What is CY3?
CY3 is an oral cutting formula from Dragon Pharma that combines clenbuterol, liothyronine (T3), and yohimbine in one tablet. Each pack holds 100 tablets and the formula is built for thermogenesis and metabolic support during dieting phases.
What does CY3 do?
The three actives work through different pathways: clenbuterol raises heat production, T3 supports overall metabolic rate, and yohimbine is referenced for mobilizing stubborn fat stores. Together they are used to keep fat loss moving when diet and cardio plateau.
How should I dose CY3?
Start with half a tablet in the morning for the first few days to check tolerance, then move to one full tablet daily. Only experienced users go higher, and only when heart rate and tremor stay under control. Morning dosing is strongly preferred.
How long should I run CY3?
Clenbuterol-based products are usually run in short blocks of 3-4 weeks with a break in between, because beta-2 receptors downregulate and the effect fades with continuous use. The break also gives the thyroid axis time to resettle after T3.
What are the side effects of CY3?
The most common effects are jitteriness, hand tremor, headache, elevated heart rate, and sleep problems when dosed late. Muscle cramps from potassium and taurine depletion are also reported, which is why electrolytes are part of any clen protocol.
Why does CY3 make me shaky and why is my heart rate up?
Clenbuterol is a beta-2 agonist and yohimbine is a stimulant, so both raise heart rate and can cause tremor, especially in the first days of use. If resting heart rate stays high or shakes are strong, lower the dose or stop rather than pushing through.
Does CY3 burn muscle?
T3 raises metabolic rate without telling the body what to burn, so in a deep deficit it can pull at muscle tissue. Keeping protein high, using a moderate deficit, and holding lean mass with anabolic support are the standard ways to protect muscle.
Can I stack CY3 with caffeine or other fat burners?
No. CY3 already contains three strong actives, and adding caffeine, pre-workouts, or any other stimulant fat burner increases the cardiovascular load without adding results. Keep other stimulants minimal for the whole block.
Does CY3 suppress the thyroid or need PCT?
Exogenous T3 can downregulate natural thyroid output while it is used, which is why continuous long runs are avoided and blocks are kept short with breaks. A SERM-style PCT is not relevant here, but a sensible taper and monitoring are wise after longer use.
Who should avoid CY3?
Anyone with heart rhythm problems, high blood pressure, hyperthyroidism, or a history of stimulant sensitivity should avoid it. The same applies to anyone cutting calories aggressively while doing heavy cardio, since the cardiovascular load stacks quickly.
