Fat Loss Stack

Why This Stack Works for Fat Loss

This stack attacks fat through growth hormone optimization — a fundamentally different approach from appetite suppression (GLP-1 drugs) or stimulant-based thermogenesis. Elevated GH drives lipolysis: the breakdown of stored triglycerides into free fatty acids for oxidation. The three peptides in this stack each contribute a distinct piece of that process.

Tesamorelin is the anchor. It is the only FDA-approved GHRH analog (approved for HIV-associated lipodystrophy under the brand name Egrifta). Its clinical track record for visceral fat reduction is unmatched in the peptide space. Tesamorelin binds to GHRH receptors on the anterior pituitary and stimulates a strong, sustained GH pulse — with particular efficacy against visceral adipose tissue.

Key clinical data:

• Reduced trunk fat by 18% over 26 weeks in Phase III trials
• Significant reduction in visceral adipose tissue (VAT) measured by CT scan
• No significant change in subcutaneous fat in the extremities — the effect is targeted
• Maintained lean body mass during fat loss
• Improved lipid profiles (reduced triglycerides)

CJC-1295 (no DAC) adds pulsatile GHRH signaling on top of Tesamorelin. While Tesamorelin provides a strong single daily pulse, CJC-1295 extends GH elevation across multiple injection windows throughout the day. This maintains lipolytic signaling during waking hours, particularly around fasted training.

Ipamorelin amplifies every GH pulse by firing the ghrelin receptor simultaneously with the GHRH signal. The dual-receptor activation (GHRH + ghrelin) produces 3-5x more GH than either alone. Ipamorelin is chosen over other GHRPs because it does not elevate cortisol (catabolic, promotes fat storage) or prolactin, and its appetite increase is mild — critical when the goal is fat loss.

The Synergy

Running all three together creates overlapping GH stimulation through the day:

• Morning (fasted): CJC-1295 + Ipamorelin → GH pulse for daytime lipolysis
• Pre-sleep: Tesamorelin + CJC-1295 + Ipamorelin → massive GH surge that amplifies the natural nocturnal GH peak

This pattern keeps growth hormone elevated across the body’s two most important fat-burning windows: the fasted morning and overnight sleep.

Standard Fat Loss Stack Protocol

Daily Schedule

Time	Peptide	Dose	Notes
Morning (fasted)	CJC-1295 + Ipamorelin	100 mcg each	Immediately upon waking, before food
Pre-sleep	Tesamorelin	1–2 mg	30 min before bed, 2+ hours after dinner
Pre-sleep	CJC-1295 + Ipamorelin	100 mcg each	Same injection window as Tesamorelin

Total daily exposure:

• Tesamorelin: 1–2 mg
• CJC-1295: 200 mcg
• Ipamorelin: 200 mcg

Simplified Schedule (Budget-Friendly)

Time	Peptide	Dose	Notes
Pre-sleep	Tesamorelin	1–2 mg	Single daily injection, fasted
Pre-sleep	CJC-1295 + Ipamorelin	100 mcg each	Combined with Tesamorelin

This drops to one injection window per day while preserving the most important GH pulse (pre-sleep).

Cycle Structure

Phase	Duration	Protocol
Active cycle	8–12 weeks	Full stack daily
Off period	4–6 weeks	No GH peptides
Repeat	As needed	Most users run 2–3 cycles per year

Maximizing Results

Fasting Protocol

This is non-negotiable for GH-based fat loss. Insulin directly suppresses GH release.

1. 2+ hours fasted before every injection
2. 30–60 minutes after injection before eating
3. Morning dose leverages the natural overnight fast
4. Pre-sleep dose: stop eating 2+ hours before bed
5. If you train fasted in the morning, inject 15–20 minutes before training — GH mobilizes fatty acids that the workout then burns

Training Strategy

GH-based fat loss works best with:

• Fasted morning cardio after the morning GH injection — fatty acids are already mobilized
• Resistance training to preserve and build lean mass — GH supports protein synthesis
• HIIT or zone 2 cardio — both leverage the elevated fatty acid availability
• Train within 60 minutes of the morning injection for maximum benefit

Nutrition Considerations

• Protein intake at 1g per pound of bodyweight — GH supports muscle preservation but only if protein is adequate
• Moderate caloric deficit (300–500 kcal) — GH handles the lipolysis, you don’t need extreme restriction
• Time carbohydrates to post-workout windows to minimize insulin interference with GH signaling
• Do not combine this stack with a very low calorie diet — the GH elevation will be wasted without adequate nutrition to support recomposition

AOD-9604 Substitution

For users who want a simpler or more affordable fat loss stack:

Peptide	Replaces	Dose	Frequency
AOD-9604	Tesamorelin	300 mcg	Once daily (fasted, morning or pre-bed)

AOD-9604 is the C-terminal fragment of human growth hormone (amino acids 177-191). It stimulates lipolysis and inhibits lipogenesis without activating the GH receptor — meaning no effect on blood sugar, no water retention, and no IGF-1 elevation. The tradeoff is weaker clinical evidence compared to Tesamorelin.

Safety Considerations

Common Side Effects

• Water retention — mild, temporary. Most noticeable weeks 1-3 (face, hands). Indicates the stack is working.
• Numbness/tingling — carpal tunnel-like symptoms from elevated GH. Dose-dependent. Reduce dose if persistent.
• Injection-site reactions — minor redness or soreness. Rotate sites.
• Joint discomfort — occasional, from GH-driven fluid shifts. Usually resolves.
• Vivid dreams — common with elevated nighttime GH. Generally considered a benefit.

Serious Considerations

Insulin sensitivity. This stack elevates GH significantly. Monitor fasting glucose and HbA1c. If fasting glucose trends above 100 mg/dL, reduce Tesamorelin dose or pause the cycle.

Not a substitute for fundamentals. GH peptides amplify fat loss from proper training and nutrition. Without a caloric deficit and adequate protein, the effect will be marginal.

Source quality. Tesamorelin is expensive and frequently counterfeited. Only purchase from vendors with third-party CoA, HPLC purity testing (99%+), and mass spectrometry confirmation.

Contraindications

• Active cancer or tumor history (GH promotes cell growth)
• Diabetes or pre-diabetes (GH affects insulin sensitivity)
• Pituitary disorders
• Pregnant or breastfeeding
• Under 18
• WADA-tested athletes (all three peptides are prohibited)
