Head-to-head comparison of CJC-1295 (no DAC) and Tesamorelin — mechanism, side effects, legal status, and pricing.
CJC-1295 without Drug Affinity Complex (no DAC), also known as Modified GRF(1-29), is a synthetic analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH). Four amino acid substitutions at positions 2, 8, 15, and 27 confer resistance to DPP-IV enzymatic degradation while maintaining GHRH-receptor binding activity. Unlike the DAC-conjugated variant (half-life 6–8 days via albumin binding), the no-DAC form has a short half-life of approximately 30 minutes, producing brief, pulsatile bursts of GH secretion. Not FDA-approved in any form.
Tesamorelin (Egrifta / Egrifta SV) is a stabilized analog of human GHRH(1-44) with a trans-3-hexenoic acid moiety at the N-terminus that protects against protease degradation. FDA-approved in November 2010 for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy, it is the only FDA-approved GHRH analog for this indication. Off-label use for general body composition and visceral fat reduction in non-HIV populations is common but outside the approved label.

Tesamorelin is among peptides under FDA review for the Category 1 (503A) list; if added, it would require a prescription to be compounded by registered 503A/503B pharmacies — not yet authorized. CJC-1295 (no DAC) remains research-only. In April 2026 the FDA removed 12 peptides from Category 2, which does not place them on the Category 1 list or authorize compounding. The FDA's Pharmacy Compounding Advisory Committee is advisory and meets July 23–24, 2026 to review nominations and make recommendations to the FDA.
The parent molecule CJC-1295 (DAC form) was identified by Jetté et al. (Endocrinology, 2005; PMID 15817669) at ConjuChem as a tetrasubstituted GHRH(1-29) bioconjugate that covalently binds Cys34 of serum albumin via a maleimidopropionyl-lysine linker, extending half-life to roughly 5.8–8.1 days. In healthy adults, Teichman et al. (JCEM, 2006; PMID 16352683) showed single SubQ doses of the DAC form produced 2- to 10-fold GH elevations for ≥6 days and 1.5- to 3-fold IGF-1 elevations for 9–11 days, and Ionescu & Frohman (JCEM, 2006; PMID 17018654) demonstrated that pulsatile GH secretion was preserved (7.5-fold increase in trough GH, IGF-1 up 45%). ConjuChem halted Phase 2 lipodystrophy development around 2006–2007 after a participant death in an HIV-visceral-adiposity trial (deemed by the trial physician most likely due to pre-existing coronary artery disease rather than CJC-1295, but the program was not resumed; aidsmap news, July 2006). The no-DAC form described here ('Modified GRF 1-29') shares the same position-2/8/15/27 substitutions (which confer DPP-IV resistance; see Soule et al., JCEM 1994, PMID 7962295 for the foundational D-Ala2 half-life work) but omits the albumin-linker lysine, giving a short (~30 min) half-life similar to sermorelin. No form of CJC-1295 is FDA-approved for any indication. Grey-market compounding practice pairs the no-DAC form with ipamorelin; this combination is not clinically validated for anti-aging, body composition, or performance use, and peer-reviewed human trials of the no-DAC variant specifically are lacking — the 100–300 mcg dosing range reflects community practice, not clinical evidence.
Key references
CJC-1295 (no DAC) and Tesamorelin are both in the Performance category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.

Lab Testing
FDA approval (NDA 022505) was based on two Phase 3 trials reported by Falutz et al. (NEJM, 2007; PMID 18057338) and the pooled 52-week safety extension, showing ~15-18% reduction in visceral adipose tissue with improved triglycerides in HIV patients with abdominal fat accumulation. Stanley et al. (JAMA, 2014; PMID 25038357) demonstrated concurrent reductions in visceral and liver fat (NAFLD). Baker et al. (Arch Neurol, 2012; PMID 22869065) reported favorable effects on executive function in older adults with and without mild cognitive impairment at 1 mg/day for 20 weeks — note this cognition signal was in MCI / healthy older adults, not specifically APOE4-positive individuals. Current label dose is 1.4 mg SubQ daily (Egrifta SV); legacy Egrifta used 2 mg/day. Off-label use for general body composition in non-HIV populations is common but outside the FDA label.
