Everything you need to know about our peptide protocols, the clinical process, safety standards, and what to expect as a patient.
Every protocol we offer is selected against peer-reviewed research, reviewed by a licensed clinician, and prepared to pharmaceutical standards at US-licensed pharmacies. This is how we think about the science — and why it matters.
Peptides are short chains of amino acids — the same building blocks your body already uses to regulate growth, repair, inflammation, metabolism, and cognition. They don't override your biology. They work with it.
What makes peptide therapy compelling isn't any single compound. It's the specificity — targeted protocols with documented mechanisms, reviewed against published research before they're offered to any patient.
Each peptide binds to specific receptors, producing defined physiological responses. Unlike broad-spectrum interventions, peptide protocols can be matched to precise clinical goals — recovery, metabolic health, hormonal balance, cognitive performance.
Every compound in our library has published research documenting its mechanism and clinical effects. We don't offer compounds based on anecdote. PubMed citations are referenced in every protocol entry in our Peptide Guide.
No protocol is dispensed without a licensed clinician reviewing your intake, health history, and goals. The science informs the selection. The physician makes the call.
Peptide research is active and evolving. We acknowledge that openly. Where evidence is strong, we say so. Where it's preliminary, we say that too. Honest science builds better outcomes.
Our protocol library is curated, not comprehensive. Every compound goes through a structured review before it's offered.
We evaluate peer-reviewed literature for documented mechanism of action, clinical study results, safety profile, and the quality of evidence. Compounds with only preclinical or anecdotal support are not included.
Research credibility alone isn't enough. We assess whether a compound is clinically appropriate for a telehealth setting — considering administration, monitoring requirements, interaction profiles, and realistic patient suitability.
A protocol is only as good as the preparation behind it. Every compound we offer must be preparable to strict sterility and purity standards at a US-licensed pharmacy. We don't work with facilities that can't meet that bar.
Independent testing consistently shows that the majority of peptides sold outside clinical channels are mislabeled, underdosed, or contaminated. RetaClinic operates exclusively with US-licensed compounding pharmacies because the preparation standard isn't negotiable.
Research chemical peptides are sold as "not for human use" and carry none of the oversight that clinical preparation requires. No sterility testing. No concentration verification. No physician review. The compound may look identical — the standards behind it are not.
US-licensed compounding pharmacies operate under state board of pharmacy oversight, follow USP sterility guidelines, and are subject to inspection. This isn't a marketing claim — it's a legal and regulatory framework with accountability attached.
Once a clinician approves your protocol, your pharmacy partner prepares and ships your prescription directly to your address. Typical turnaround is a few business days. Tracking is provided.
Every protocol follows the same four-step clinical pathway — from intake to your door.
Browse our catalog by goal or compound. Use the Peptide Guide to understand the research before you decide. Add to cart when you're ready.
A structured intake form covers your health history, current medications, goals, and any relevant background. Takes about five minutes.
A licensed clinician reviews your intake — typically within hours. They approve, request clarification, or decline if the protocol isn't right for your profile.
If approved, your prescription is issued and sent to our pharmacy partner for preparation. Shipped directly to you, with tracking. Refunded in full if not approved.
A selection of published studies informing our protocol library. Full citations are available in the Peptide Guide.
24.2% mean body weight reduction at 48 weeks in phase 2 clinical trial — the largest reduction reported for any obesity medication at the time of publication.
Accelerated tendon outgrowth and fibroblast proliferation in connective tissue repair models, with documented angiogenic and anti-inflammatory activity.
SURMOUNT-1: 20.9% mean weight loss vs 3.1% placebo at 72 weeks. 91% of participants lost ≥5% body weight. Dual GIP/GLP-1 mechanism.
Dose-dependent GH increases with no significant changes in cortisol, prolactin, or ACTH — a clean GH pulse profile with minimal off-target effects.
Annual courses associated with lower all-cause mortality over a 12-year follow-up in aging adults vs untreated controls. Telomerase activation documented in vitro.
Significantly increased wound healing rate and collagen deposition in full-thickness dermal wound models. Copper peptide declines with age; topical and injectable forms studied.
Research notice. The studies referenced above are provided for informational context and reflect the scientific literature informing our protocol selection. Peptide research is ongoing and evolving. Individual results will vary. Nothing on this page constitutes medical advice or a guarantee of outcome. All protocols require physician review and a valid prescription prior to dispensing.
