Compare therapies & protocols
Plain-language, clinician-reviewed comparisons of the compounds, modalities, pharmacy models, and delivery routes that come up most often during a Regen Therapy intake. Each page includes a side-by-side table, a decision-guide framing, and answers to the questions we hear most.
GLP-1 & Metabolic
2 comparisonsHow the GLP-1, GIP, and triple-agonist therapies differ on receptor target, dosing, and clinician considerations.
Oral vs Injectable Semaglutide
How oral and injectable semaglutide compare across formulation, dosing, bioavailability, regulatory status, and clinician fit.
Semaglutide vs Tirzepatide vs Retatrutide
How semaglutide, tirzepatide, and retatrutide compare across receptor target, dosing schedule, regulatory status, and clinician considerations.
Growth Hormone Axis
2 comparisonsSermorelin, CJC-1295, ipamorelin, and tesamorelin compared by mechanism, half-life, and intended use.
AOD-9604 vs Tesamorelin
How AOD-9604 (a GH fragment) and tesamorelin (a stabilized GHRH analog) compare across mechanism, regulatory status, dosing, and clinician fit.
Sermorelin vs CJC-1295/Ipamorelin vs Tesamorelin
How sermorelin, CJC-1295/ipamorelin, and tesamorelin compare across mechanism on the growth-hormone axis, dosing, and regulatory status.
Tissue Support
1 comparisonPeptide options used clinically for tissue and recovery support.
Modality
4 comparisonsCompare entire modalities — peptides, SARMs, and TRT — at the level of mechanism and oversight.
Melatonin vs DSIP
How melatonin and DSIP (delta sleep-inducing peptide) compare across mechanism, route, regulatory status, and clinician fit in sleep-related contexts.
Peptides vs SARMs vs TRT
How peptide therapy, SARMs, and TRT differ in mechanism, regulatory status, and how clinicians evaluate them — written for general orientation.
PT-141 vs Oxytocin
How PT-141 (bremelanotide) and oxytocin compare across mechanism, route, regulatory status, and how clinicians evaluate them in sexual-health contexts.
Testosterone Cypionate vs Enanthate vs Pellet
How testosterone cypionate, enanthate, and subcutaneous pellet therapy compare across ester, half-life, dosing schedule, and clinician monitoring.
Pharmacy & Compliance
1 comparisonHow 503A and 503B compounding pharmacies differ in oversight, scale, and dispensing model.
Delivery Routes
2 comparisonsSubcutaneous, intramuscular, oral, nasal, and topical — how delivery route shapes a peptide protocol.
NAD+ IV vs SC vs Oral
How NAD+ delivered as an IV infusion, subcutaneous injection, or oral troche compares across absorption, schedule, supplies, and clinician fit.
Oral vs Injectable vs Nasal vs Topical
How oral, injectable, nasal, and topical delivery routes for peptides and related therapies compare across absorption, onset, and clinical fit.
