What is Tesamorelin?

Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), developed to treat HIV-associated lipodystrophy by reducing visceral adipose tissue. It is FDA-approved specifically for this condition, marking it as one of the few peptides with such approval. While effectively reducing trunk fat, its use incurs the risk of increased diabetes and glucose intolerance.

Primary Benefits

Reduces visceral fat. Improves lipid profiles. Enhances body composition.

How It Works

Tesamorelin binds to GHRH receptors on pituitary somatotroph cells, stimulating the release of growth hormone (GH). This leads to increased lipolysis, primarily targeting visceral adipose tissue, while sparing subcutaneous fat. The action elevates circulating IGF-1 levels, facilitating fat loss and metabolic improvements.

  • 3.DON'T use if you have pituitary gland disorders.
  • 4.NEVER inject into the same site repeatedly without rotation.
  • 5.DON'T mix with alcohol or tobacco while on treatment.
  • 6.AVOID use if you are pregnant or breastfeeding.
  • 7.DON'T skip regular glucose monitoring if diabetic.
  • 8.NEVER purchase from non-verified sources to avoid contamination.

Frequently Asked Questions

Common questions about Tesamorelin

How long until I see effects?

With Tesamorelin, IGF-1 levels rise in 1-2 weeks, and visible fat reduction is typically observed between 8-12 weeks.

What time of day should I take it?

It's best to administer Tesamorelin before bed on an empty stomach to synchronize with the body's natural GH release.

How can I minimize side effects?

To minimize side effects when using Tesamorelin, ensure correct injection techniques and regular glucose monitoring, especially if you're diabetic.

Does tolerance develop?

Tolerance is not typically reported with Tesamorelin, but regular assessment and consultation with a healthcare provider are advised.

How should I store it?

Store the reconstituted Tesamorelin solution at room temperature and use it within 7 days.

Do I need to cycle it?

For FDA-approved use, cycling is not typically required, but consult your healthcare provider for off-label uses.

Safety Tips

  • Always consult a licensed medical professional for dosing and reconstitution instructions.
  • Always double check your units. Mixing up mg and mcg can be very dangerous.
  • Make sure to select your syringe type. U-100 and U-50 syringes have different units.
  • Ensure you're not adding more BAC than your vial can hold. Most vials have maximum capacities listed.
