Description
Spartan 2 combines CJC-1295 and GHRP-2 in one product. Every batch is tested for 99% purity or better, and it’s sold for laboratory research only.
What’s in Spartan 2?
CJC-1295 (no DAC)
CJC-1295 without DAC, also called modified GRF(1-29), is GHRH(1-29) with four amino acid changes that protect it from enzymes. Its half-life is longer than sermorelin’s, though still short.
CJC-1295 without DAC binds the GHRH receptor on pituitary somatotrophs and switches on cAMP signaling, which releases a GH pulse. Its four amino acid changes protect it from DPP-4, the enzyme that breaks down natural GHRH.
GHRP-2
GHRP-2 (pralmorelin) is a six-amino-acid synthetic peptide that acts on the ghrelin receptor and makes the pituitary release growth hormone. It came out of the growth hormone releasing peptide program started by Cyril Bowers at Tulane University.
GHRP-2 binds GHS-R1a, the receptor that ghrelin uses. In the pituitary that triggers GH release, and in the hypothalamus it adds to the GHRH signal and damps somatostatin, the hormone that holds GH back.
The idea behind Spartan 2
Labs pair these compounds because each works through a different pathway, so combining them covers more of the system in one study. A fixed mix also means one product, one label and no drift between separate containers.
Spartan 2 research background
The amino acid changes were described in work on tetrasubstituted GRF analogs.
Bowers and colleagues published a series of human studies in the 1990s showing that GHRP-2 raised GH in a dose-related way, and that giving it with GHRH produced a much bigger GH pulse than either one alone.

Study design notes
When labs combine compounds, they usually keep the total peptide amount and the mixing volume the same across groups. That way any difference comes from the combination, not the handling.
Record the ratio on every label, especially once vials are mixed.
A clean combination study has at least four groups: vehicle, compound A, compound B and A plus B. That’s the only way to tell whether the mix does more than either part.

How we test each batch
Every batch is tested before it goes on sale. Identity is checked by mass spectrometry, and purity by HPLC, with a target of 99% or higher.
Each container is labeled with the product, the amount and the batch number. Email us that number and we’ll send the certificate of analysis for your batch.
Keeping it fresh
Store capsules, tablets and powder in a cool, dry place out of direct light, with the lid closed tight. Write the date you opened or mixed it on the label, so anyone else in the lab knows how old it is.
Working with it safely
Treat it as a lab chemical. Gloves and safety glasses are the minimum, and a clean, uncluttered workspace cuts down on mix-ups.
Store prepared solutions apart from untouched stock, and record who mixed what and when.

How it compares
ACTH 1-34: ACTH 1-34 is the first 34 amino acids of adrenocorticotropic hormone, the 39-amino-acid pituitary hormone that controls cortisol release. The first 24 amino acids carry the full hormone activity.
HGH Fragment 176-191: HGH Fragment 176-191 is the last 16 amino acids of human growth hormone, with the disulfide bond from the parent protein. It’s the region of GH linked to fat breakdown, without the parts that bind the GH receptor and drive growth.
