Mechanism, evidence, legal path, cost — all side-by-side.
Earlier-generation GH secretagogue, predates ipamorelin. Stronger GH spike than ipamorelin but less selective — measurable cortisol/prolactin elevation in some users. Investigated diagnostically for GH deficiency; off-label use for body composition is grey-market common.
Emerging hormonal signal with real mechanistic basis — but this is where subjective monitoring most consistently misleads. Hormonal shifts at this tier are often lab-detectable before they become subjectively felt. Without bloodwork at 6–8 weeks, you are tracking the wrong signal.
More side-effect profile than ipamorelin (cortisol, prolactin, hunger). Off-label use without IGF-1 monitoring carries long-term unknown.
D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys (5 aa with D-stereoisomers and unnatural residues).

Expected reclassification — PCAC review Feb 2027
FDA's Pharmacy Compounding Advisory Committee scheduled to review the second cohort of peptides removed from Category 2 in April 2026. Panel votes whether to add each to the official 503A bulks list.
Pre-filled with this compound's published dose range: 100-300 µg · 2-3x daily, subcutaneous
Calculator is a discussion tool. Verify reconstitution + dosing with a qualified provider. Stack is not a prescription source. Use sterile technique and inspect every vial.
How much a first cycle actually costs across the channels people use. Pick the protocol length you're considering — Stack multiplies the monthly band by cycle weeks. Same caveats apply: ranges are facts, quality varies, this is not legal advice.
Numbers reflect publicly-advertised price ranges, not vendor quotes. Insurance, prescription costs, and shipping aren't included. Channels marked unavailable are filtered out.
See pharmacies for this compound →Approximate monthly cost across the channels users actually consider — brand FDA-approved retail, US 503A compounding, Mexican pharmacies, MX farmacias magistrales, and the research-grey market. Stack lists ranges, not vendor names. Quality varies wildly across channels — see each band's note.
Dosing assumption: 100-300 µg three times daily subcutaneous (growth hormone releasing peptide)
Research-grey only. Often paired with CJC-1295 in growth-hormone protocols. Quality varies wildly — third-party COA scarce on the cheap end. On the Feb 2027 PCAC docket.
