CJC-1295 + Ipamorelin + Tesamorelin + IGF-1 LR3 - Atlas
Also indexed as Atlas
1 Identity
Fixed-ratio four-component article: a 30-residue peptide-maleimide conjugate, a five-residue pentapeptide amide with two non-proteinogenic residues, an N-acylated 44-residue peptide amide, and an 83-residue recombinant refolded protein with three intramolecular disulfides, co-lyophilized. Two of the four are GHRH(1-29)-family molecules on the same scaffold and one is a folded protein, which together set the analytical class of the whole article. A brand name states no composition and no ratio and is not accepted alone on a certificate or a specification. As with every CJC-1295 title, the second name is ambiguous - the DAC-bearing conjugate at 3,647.250 Da against CJC-1295 no DAC, trade usage for Modified GRF (1-29) at 3,367.954 Da - so this record is written for the DAC-bearing conjugate and the specification names it in full.
Contains CJC-1295 + Ipamorelin + Tesamorelin + IGF-1 LR3
- Sequence
- Stated per component; the full sequences live on the component records and are not restated here. The blend-relevant facts are these. CJC-1295 (DAC:GRF) is the tetrasubstituted GHRH(1-29) scaffold plus Lys30 bearing a 3-maleimidopropionyl group. Tesamorelin is the trans-3-hexenoyl-capped 44-mer amide, sharing 27 of the first 29 positions with it. Ipamorelin is Aib-His-D-2-Nal-D-Phe-Lys-NH2. IGF-1 LR3 is a 13-residue leader fused to human IGF-1(1-70) carrying Glu3Arg, 83 residues in total, so the mature segment begins GPR- and not GPE-, with six cysteines and three disulfides at Cys19-Cys61, Cys60-Cys65 and Cys31-Cys74 in 83-residue numbering.
- Molecular formula
- Stated per component. A mixture has no combined formula and none is written. CJC-1295 (DAC:GRF) C165H269N47O46. Ipamorelin C38H49N9O5. Tesamorelin C221H366N72O67S as the free base, supplied as the acetate. IGF-1 LR3 C400H619N111O115S9 with all three disulfides formed, C400H625N111O115S9 fully reduced. Counterion is a measured finding per component, and the protein is not a simple peptide salt: it is supplied either as a lyophilized free base or in an acetate-buffered matrix, and which one is a specification statement rather than an assumption.
- Average mass
- Per component: CJC-1295 (DAC:GRF) 3,647.250 Da; ipamorelin 711.868 Da; tesamorelin 5,135.856 Da as the free base; IGF-1 LR3 9,111.55 Da oxidized and 9,117.60 Da fully reduced, the +6.05 Da gap being the arithmetic that proves three disulfides are formed. AT A nominal 10 mg + 10 mg + 10 mg + 1 mg fill, 31 mg total, the molar amounts are 2.74179, 14.04755, 1.94710 and 0.10975 micromol, a ratio of 24.98 : 127.99 : 17.74 : 1.00 against the protein. A 1 mg protein in a 31 mg fill is a trace constituent by mole count, whatever a trade document calls it, and a 12.8-fold molecular-weight spread across four components makes any mass-based description of this article as balanced simply wrong.
- Monoisotopic mass
- Per component, and monoisotopic is not the release measurement on the protein. CJC-1295 3,645.01548, [M+3H]3+ 1,216.0124. Ipamorelin 711.3857, [M+H]+ 712.3930. Tesamorelin 5,132.71664, used with a deconvoluted envelope. IGF-1 LR3 9,105.3487 oxidized and 9,111.3957 reduced, quoted as reference values because at 9 kDa the monoisotopic peak is not the base peak of the isotope envelope; a usable certificate reports a deconvoluted average with the charge-state series printed. The mass test the protein defeats: scrambled-disulfide isomers are exactly isobaric with correctly folded material and frequently co-elute, so only peptide-map disulfide connectivity distinguishes them. Two further named species are required output: des-acyl tesamorelin at -96.058 Da and the maleamic-acid degradant at +18.015 Da. No single blend molecular weight is printed.
- Salt / variant note
- (1) scrambled-disulfide isomers of the protein: exactly isobaric, frequently co-eluting, the principal quality variable in refolded material and invisible to mass and RP-HPLC alike. (2) the fully reduced protein at +6.05 Da. (3) the construct fork: IGF-1 LR3 against IGF-1 des(1-3) and native IGF-1(1-70), the GPE- against GPR- mature N-terminus being the check. (4) the DAC fork: 3,647.250 against 3,367.954. (5) des-acyl tesamorelin at -96.058 Da, together with the isobaric acyl isomers, which the mass alone will not separate. (6) Counterion per component; ratio not standardized across listings.
2 Class & testing panel
- Form
- Fixed-ratio blend
- Testing panel
- P3, P2 and P4 — panel definitionas a union, run per component and never once for the vial. P3 is engaged twice - D-Ala2 in CJC-1295, and Aib1, D-2-Nal3 and D-Phe4 in ipamorelin - so chiral amino acid analysis runs against each component's own expected D-content and is never pooled; the other two components contain no D-residue and no chiral limit is written for them. P2 governs tesamorelin's acyl group, and des-acyl material is reported as a named species. P4 governs the recombinant protein and brings disulfide connectivity mapping, host-cell protein, host-cell DNA, endotoxin, aggregate content by size-exclusion chromatography and an expression-host declaration, attributes no peptide panel carries. The conjugate adds intact maleimide content and a free-thiol determination. This is the worst-conditioned article in the group for amino acid analysis: the recombinant protein contributes seven prolines, three methionines and seven glycines to a vial that already holds two GHRH(1-29)-family molecules, which leaves neither tesamorelin nor CJC-1295 with a unique marker residue, and both are then reachable only through a difference chain three deep that rests on the 1 mg component
3 Primary sources & evidence
What follows reports study design and provenance, not a conclusion about effect. Literature exists for each component and sits on that component's own record in this catalog. The tesamorelin record rests on registrational trials, cited by identifier: Falutz et al., N Engl J Med 2007;357:2359-2370, PMID 18057338, DOI 10.1056/NEJMoa072375; and Falutz et al., J Clin Endocrinol Metab 2010;95:4291-4304, PMID 20554713, DOI 10.1210/jc.2010-0490. The protein component's record rests substantially on cell-culture and bioprocess literature rather than on clinical designs. Combination literature: none identified. No published study of this fixed four-component combination at any ratio was identified; that is a statement about the published record and not a conclusion about any component.
4 Storage & specification
- Storage
- Co-lyophilized solid in Type I amber glass with a nitrogen headspace, desiccated and light-protected, stored at -20 degrees C plus or minus 5 degrees C. Non-sterile laboratory chemical, no sterility claim. The protein governs the handling rules: repeated freeze-thaw is the aggregation pathway for refolded material, so the article is subdivided once into single-use units rather than thawed and refrozen. Two further written conditions follow from the chemistry rather than from convention. Water is a reactant here, not just a specification line, because the maleimide hydrolyzes in its presence, which makes Karl Fischer determination a release attribute. And free thiols and reducing agents are incompatible with this article on two counts at once, being a quench for the maleimide and a reductant for the protein's three disulfides; the incompatibility is carried on the label.
- Shelf life
- Provisional 24 months at -20 degrees C plus or minus 5 degrees C, desiccated and light-protected, with a mandatory interim pull on each of the first three lots. The retest-limiting attributes are split between two chemistries that do not usually share a vial: maleimide hydrolysis to the maleamic acid at +18.015 Da on the conjugate, and protein attributes, namely aggregate content by size-exclusion chromatography and disulfide scrambling by non-reduced peptide map. Des-acyl tesamorelin at -96.058 Da follows those, with per-component net content, the measured ratios, water and counterion trended alongside. The blend runs its own protocol and inherits no component study.
This record reports identity, specification and study design. It does not state what the article does in a human body. Supplied under the caution: “CAUTION: Contains a new drug for investigational use only in laboratory research animals or for tests in vitro. Not for use in humans.”
