Growth Hormone Peptides
for Research
CJC-1295 w/DAC, Ipamorelin, and Tesamorelin are the most-studied GH secretagogue compounds in preclinical and clinical research. Research-grade, 99%+ purity, Aegis COA on every order.
What the Research Covers
Growth hormone axis research investigates how synthetic peptides modulate GH secretion, IGF-1 production, and the downstream effects on metabolism, body composition, and cellular function. The primary research tools in this category are GHRH analogues (which stimulate GH release via the GHRH receptor) and GH secretagogue receptor agonists (which act through the ghrelin receptor pathway). CJC-1295 w/DAC, Ipamorelin, and Tesamorelin each represent distinct approaches to GH axis modulation with well-documented preclinical and clinical research profiles.

They are not approved for clinical or therapeutic applications except where specifically noted from regulatory history. Researchers should source compounds with batch-specific COA documentation confirming purity and molecular identity to ensure reproducible results.
GH Secretagogue Research Compounds
CJC-1295 w/DAC
CJC-1295 with Drug Affinity Complex
$149.99 / 10mg
CJC-1295 w/DAC is a synthetic GHRH analogue engineered with a Drug Affinity Complex modification that enables albumin binding, extending its plasma half-life to several days per dose. Research has examined its ability to produce sustained increases in GH pulse amplitude and cumulative IGF-1 response compared to short-acting GHRH analogues. It is frequently studied alongside GHSR agonists in combination GH axis research protocols.
Ipamorelin
Ipamorelin (Pentapeptide GH Secretagogue)
$139.99 / 10mg
Ipamorelin is a pentapeptide growth hormone secretagogue receptor (GHSR) agonist distinguished by its selectivity profile. Research has documented GH stimulation with minimal effects on cortisol or prolactin, making it valuable for studies requiring isolated GH axis effects. Studies have examined its synergistic activity with GHRH analogues, its GH pulse characteristics, and downstream IGF-1 responses in various animal models.
Tesamorelin
Tesamorelin (Synthetic GHRH Analogue)
$99.99 / 10mg
Tesamorelin is a synthetic analogue of human GHRH with an FDA-approved clinical indication for HIV-associated lipodystrophy, giving it one of the most well-documented research profiles in the GH secretagogue category. Studies have examined its effects on GH secretion, IGF-1 modulation, visceral adipose tissue reduction, and body composition. Its regulatory history makes it a unique reference compound for GH axis research.

GH Secretagogue Research: Common Questions
What growth hormone peptides are available for research?
Blackwell BioLabs supplies three primary GH axis research compounds: CJC-1295 w/DAC, Ipamorelin, and Tesamorelin. CJC-1295 w/DAC is a long-acting GHRH analogue studied for sustained GH pulse stimulation. Ipamorelin is a selective GHSR agonist with a clean stimulation profile. Tesamorelin is an FDA-approved GHRH analogue with a well-documented research base. All three are available with Aegis Analytical COA at 99%+ purity.
How does CJC-1295 w/DAC differ from native GHRH?
Native GHRH has a very short plasma half-life due to rapid enzymatic degradation. CJC-1295 with DAC modification extends this by binding to serum albumin, creating a depot effect that prolongs GH stimulation to several days per dose. Research has documented significant differences in GH pulse amplitude, duration, and cumulative IGF-1 response compared to short-acting GHRH.
Why is Ipamorelin considered selective in GH secretagogue research?
Ipamorelin stimulates GH secretion with minimal effects on cortisol, ACTH, or prolactin, unlike GHRP-2 and GHRP-6. This selectivity makes it valuable for research designs requiring isolated GH axis effects without confounding hormonal variables. Studies have also examined its synergistic activity with GHRH analogues in combination research models.
Can CJC-1295 and Ipamorelin be studied together in research protocols?
Yes. The two compounds act through complementary mechanisms: GHRH analogues stimulate GH release via the GHRH receptor, while GHSR agonists act via a separate receptor pathway. Research in animal models has shown synergistic effects on GH pulse amplitude when the two mechanisms are combined.
How does Tesamorelin relate to the GH axis?
Tesamorelin is a 44-amino-acid GHRH analogue that stimulates GH secretion from the anterior pituitary. Its FDA-approved indication for HIV-associated lipodystrophy provides one of the most comprehensive clinical data sets in the GHRH analogue category. Research has documented its effects on GH pulse stimulation, IGF-1 elevation, and visceral adipose tissue reduction.
What purity standard applies to GH research peptides?
All Blackwell BioLabs GH secretagogue compounds are verified at 99%+ purity with batch-specific Certificates of Analysis from Aegis Analytical, an independent third-party laboratory. Mass spectrometry confirms molecular identity on every production batch.
Do GH secretagogue peptides require cold-chain shipping?
Lyophilized peptides are stable at ambient temperatures for short shipping periods when kept away from heat, light, and moisture. Extended storage in lyophilized form is best at refrigerated or frozen temperatures. Blackwell BioLabs includes batch-specific COA with compound storage specifications on every order.
