Muscle Growth & Growth Hormone
The muscle growth & growth hormone category brings together the growth hormone secretagogues and anabolic research peptides — CJC-1295, Ipamorelin, Tesamorelin, IGF-1 LR3 and more. Studied within sports and performance research, lab-verified and for research purposes only.
Secretagogues and blends
Ipamorelin and CJC-1295 (no DAC) are often studied together; the CJC-1295 + Ipamorelin blend combines them in one vial. CJC-1295 with DAC has a longer half-life. Tesamorelin and IGF-1 LR3 are studied within growth hormone research.
Reconstitution and handling
These peptides are supplied as freeze-dried powder and reconstituted with bacteriostatic water. See our reconstitution guide for the research-level steps.
FAQ
What is the difference between CJC-1295 with and without DAC?
The DAC variant (Drug Affinity Complex) has a longer half-life than the no-DAC variant. Both are offered for research only.
Have these peptides been tested for purity?
Yes, every batch is independently tested by Janoshik at ≥99% purity with a COA available on request.
