Tesamorelin is a synthetic peptide and growth hormone-releasing hormone (GHRH) analog, classified as an injectable peptide in this 5 mg vial from Dragon Pharma. Approved for reducing visceral fat in HIV lipodystrophy, it's used off-label in bodybuilding for GH release, fat loss, and muscle growth. Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water, it has no hepatotoxicity, no aromatization, and manageable side effects when used responsibly.
Tesamorelin binds to GHRH receptors in the pituitary gland, stimulating the release of endogenous growth hormone (GH), which elevates insulin-like growth factor-1 (IGF-1) levels. This promotes lipolysis (fat breakdown), particularly visceral fat, and protein synthesis for muscle repair. It's more potent than native GHRH due to its stability. Users notice fat loss and improved body composition within weeks.
With a half-life of approximately 30 minutes, Tesamorelin requires daily injections for optimal effects. It doesn't interact with androgenic or estrogenic pathways, ensuring no hormonal disruptions. What doesn't happen: no HPTA suppression, no water retention, and no liver toxicity, making it ideal for fat-loss protocols.
Mild side effects like injection site reactions may occur, manageable with proper technique.
Tesamorelin excels for bodybuilders seeking fat loss and GH optimization, requiring a calorie-controlled diet and training to maximize its effects.
Best for bodybuilders and athletes seeking fat loss, muscle growth, and GH enhancement; suitable for men and women with medical oversight. Not recommended for those with peptide allergies or without injection knowledge.

Tesamorelin is potent for GH release and fat loss, but peptides like CJC-1295 or Ipamorelin combinations may provide stronger or more sustained GH pulses. Full GHRH analogs or GH secretagogues like MK-677 offer alternative strengths. Consult professionals to compare efficacy and safety for your goals.
CJC-1295: Synergizes for enhanced GH release.
Ipamorelin: Complements for stronger GH pulses with minimal side effects.
GHRP-2: Boosts GH and appetite for bulking.
Cycle Support: Enhances overall wellness during protocols.
Tesamorelin vs Sermorelin: Tesamorelin is more potent for fat loss; Sermorelin is milder with broader GH benefits.
Tesamorelin vs Ipamorelin: Tesamorelin targets visceral fat; Ipamorelin offers general GH release with less potency.
Tesamorelin vs HGH: Tesamorelin stimulates natural GH; HGH provides direct supplementation with higher cost.
Review labs with a professional where lawful to ensure authenticity and safe dosing. Tesamorelin is FDA-approved for specific uses but off-label in bodybuilding.
Tesamorelin requires no PCT as it doesn't suppress testosterone or HPTA; align with steroid stack's PCT if combined (e.g., 3-4 days post-short ester). Use tamoxifen or clomiphene for 4 weeks if needed, guided by bloodwork.
