What is CJC-1295?

CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH). It is studied in two forms: "no DAC" (also called Mod GRF 1-29), which is short-acting, and "with DAC" (Drug Affinity Complex), which binds albumin for a markedly longer half-life in research models.

CJC-1295 research focuses on stimulation of the pituitary to release growth hormone in pulses. The DAC version extends the active window, while the no-DAC version produces a sharper, shorter pulse often studied alongside a GHRP such as Ipamorelin for synergistic release.

What is Tesamorelin?

Tesamorelin is a stabilized analog of growth-hormone-releasing hormone studied for its reported effect on visceral adipose tissue - the fat surrounding internal organs - in metabolic research models.

Tesamorelin stimulates endogenous GH release like other GHRH analogs, with research focused specifically on visceral-fat endpoints rather than subcutaneous fat.

Key research differences

The two are best understood by what each is studied for. CJC-1295: The DAC form trades fewer administrations for a longer, flatter profile; the no-DAC form is studied for sharper, more physiologic pulses. Choice depends on the research kinetics of interest. Tesamorelin: Tesamorelin is studied for visceral fat specifically, distinguishing it from AOD 9604 (general lipolysis) and the GLP-1 peptides (appetite).

How researchers choose between them

CJC-1295 and Tesamorelin belong to different research categories (Growth Hormone & Muscle versus Fat Loss & Weight Management), so they are usually chosen for different research questions rather than as direct substitutes. Some protocols study them together to cover complementary endpoints. Whichever you select, compare on verified quality: both are third-party tested to a 99%+ purity target with a COA on request.

Frequently asked questions

What is the difference between CJC-1295 and Tesamorelin?

CJC-1295 is a GHRH analog studied for growth-hormone-release research, with and without DAC, while Tesamorelin is a GHRH analog studied for visceral-fat and metabolic research. They belong to different research categories (growth hormone & muscle research versus metabolic research). Both are research-use-only.

Can CJC-1295 and Tesamorelin be studied together?

In some research designs, yes - they cover different endpoints, so a protocol may include both. Any combination work is laboratory research only. CJC-1295: The DAC form trades fewer administrations for a longer, flatter profile; the no-DAC form is studied for sharper, more physiologic pulses. Choice depends on the research kinetics of interest.

Which is better, CJC-1295 or Tesamorelin?

Neither is universally "better" - the right choice depends on the research question. Match the compound to your model's target signal, and compare suppliers on verifiable third-party purity, not sticker price. Tesamorelin: Tesamorelin is studied for visceral fat specifically, distinguishing it from AOD 9604 (general lipolysis) and the GLP-1 peptides (appetite).

What sizes are CJC-1295 and Tesamorelin supplied in?

CJC-1295 is supplied in 2 mg and 5 mg research sizes and Tesamorelin in 5 mg and 10 mg, both as lyophilized (freeze-dried) powder in sealed vials that are reconstituted in the lab before use in a liquid research model.

Are CJC-1295 and Tesamorelin FDA approved?

No. The research-grade CJC-1295 and Tesamorelin supplied here are not FDA-approved drug products; they are sold strictly for laboratory and in-vitro research. Where an approved pharmaceutical form of either compound exists, it is a separate prescription product made to clinical standards. Research material is not for human or animal consumption.
