same peptide FAQ

Dose both peptides at equimolar concentrations and measure serum GH at 15-minute intervals for 2 hours post-administration. Hexarelin will produce a significantly higher GH peak (often 2–3× greater than GHRP-6 at equivalent doses), but the temporal profile will be similar. Rapid spike followed by return to baseline. GHRP-6's moderate appetite stimulation may confound metabolic endpoints if your model involves feeding behavior, whereas Hexarelin's appetite effects are minimal. Consider using CJC-1295/Ipamorelin as a comparator if sustained GH elevation is a study variable.

A 70-amino-acid sequence indicates you received native IGF-1, not the Long R3 analog. This substitution error eliminates the extended half-life and IGFBP resistance that justify using the analog in the first place. Reject the batch and request replacement with documented proof of the 83-residue sequence. For high-stakes protocols, consider ordering a small verification sample before committing to bulk quantities. Sequence confirmation via mass spectrometry takes 3–5 business days and prevents mid-protocol failures.

No. Treat it as identical to GHRP-6 Acetate. The absence of 'Acetate' in the product name does not mean a different counterion was used or that the peptide is impure. It means the supplier omitted the salt designation from the label. Verify purity through the certificate of analysis (CoA), not the product name. Real Peptides provides HPLC verification for every batch regardless of labeling conventions, ensuring you receive the exact amino acid sequence expected for GHRP-6 at ≥98% purity.

Cloudiness indicates incomplete dissolution or contamination. GHRP-6 Acetate should dissolve completely in bacteriostatic water to form a clear solution within 60–90 seconds of gentle swirling. If cloudiness persists, do not use the solution. Particulate matter suggests protein aggregation or microbial contamination. Store lyophilized peptides at −20°C before reconstitution and refrigerate reconstituted solutions at 2–8°C. Temperature excursions above 25°C during shipping can denature peptides, causing visible aggregation that no amount of mixing will resolve.

Verify the CAS number on both product listings. If both show CAS 946870-92-4, they're the same peptide sold under two names. Potentially at different purity grades or vial sizes, but not different molecular structures. If the CAS numbers differ, contact the supplier directly for sequence verification. We've encountered cases where a supplier mistakenly listed recombinant human IGF-1 (CAS 67763-96-6) under an 'LR3' product code due to database entry errors. The CAS mismatch caught the error before shipment.
