Post firework show downtown is complete mess. Give yourself 30 minutes to get out of downtown.

I’ve been taking 50 mg three times a week NAD and 1 mg a week of Reta. After five weeks I’m already down 12 pounds and holding sustainable energy!

Tesamorelin gets brought up a lot in GH-axis discussions but it works very differently from the GHRP-class peptides. Here's the research-context breakdown for anyone digging into the literature.

What Tesamorelin is

Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), the natural 44-amino-acid hormone that signals the pituitary to release GH. The modification is a hexenoic acid attached to the N-terminus, which protects the peptide from rapid degradation by DPP-4. The result is a longer-acting GHRH signal compared to native GHRH (which has a half-life under 10 minutes).

How it differs from CJC-1295 and from Ipamorelin

This is the comparison that gets confused most often:

• Tesamorelin: stabilized GHRH analog, intermediate half-life (~30 minutes), no DAC modification
• CJC-1295 (with DAC): GHRH analog with extended albumin-binding half-life (days)
• CJC-1295 (without DAC, sometimes called "Mod GRF 1-29"): same backbone, shorter half-life
• Ipamorelin: NOT a GHRH analog. It's a ghrelin receptor agonist. Different pathway entirely.

So Tesamorelin and CJC-1295 are cousins (both GHRH analogs). Ipamorelin is from a different family.

Key research observations

• Sustained pulsatile GH release in preclinical models without the receptor-desensitization seen with continuous GH dosing
• Most-studied research application: visceral adipose tissue reduction in HIV-lipodystrophy clinical research models (this is the only FDA-approved indication, marketed as Egrifta in that specific population)
• Research in non-clinical contexts: lean mass preservation, lipid metabolism markers, IGF-1 elevation
• Does NOT independently affect ghrelin, cortisol, or prolactin pathways

Research dosing context

• Typical research doses observed in literature: 1-2 mg subcutaneously per day
• Half-life intermediate (~30 min systemic, but downstream GH effects last several hours)
• Often run in 12-week research panels in animal/cell models

Caveats

• Approved for one narrow clinical indication only
• All other research applications are exploratory
• Not for human consumption outside that specific clinical use
• Spartan compounds are research-grade only
