Peptide guide

Peptide therapy: what Northline prescribes, what it watches, and why that line matters.

Peptide therapy is a broad term, but broad language is exactly what creates confusion. Northline's position should be narrower: explain which peptides are available today, which ones remain on watch, and how legal status and medical review control the menu.

Key takeaways
Peptide therapy is not one treatment category with one evidence standard or one legal status.
Northline should separate available compounds from watchlist compounds every time it publishes on peptides.
Regulatory status matters as much as mechanism or patient demand in this category.
The strongest peptide pages help users understand current access, not just potential future access.

What peptide therapy means on this site

On Northline, peptide therapy should refer to the practice’s peptide-related formulary and tracking pages, not a catch-all promise about every peptide users see discussed online. That distinction matters because some compounds are available under current sourcing and compounding constraints while others are not.

The public site already has the right base structure for this: compound pages, watchlist language, and explicit statements that Northline will not prescribe what cannot be sourced compliantly.

What Northline lists as available today

Semaglutide
GLP-1 support for appetite, weight, and metabolic care
Tirzepatide
Dual-incretin support for appetite, weight, and metabolic care
Sermorelin
GH secretagogue · strength, sleep, recovery
NAD+
Cellular energy, longevity pathway
B12-MIC
Energy, metabolic methylation
Glutathione
Master antioxidant, detox
Methylene Blue
Mitochondrial, cognitive
Lipo-C
Lipid metabolism, weight support
L-Carnitine
Fatty-acid oxidation, performance

What remains on watch

BPC-157
BPC-157 was moved to the FDA 503A Category 2 bulk substances list in 2023, making it ineligible for routine compounding. HHS has signaled intent to review reclassification. Northline does not prescribe Category 2 substances. Members are first notified on any FDA ruling.
TB-500
TB-500 (thymosin beta-4 fragment) is on the FDA 503A Category 2 list. Compounding is currently prohibited. Northline tracks reclassification and will notify members of any change in status.
GHK-Cu
GHK-Cu is listed as a Category 2 bulk substance under the FDA 503A framework, making injectable compounding non-compliant. Topical formulations have a different regulatory standing. Northline monitors reclassification.
Thymosin α-1
Thymosin alpha-1 (Zadaxin) is approved in over 35 countries but not by the FDA for US marketing. It is on the 503A Category 2 list, prohibiting routine compounding. Northline monitors US regulatory developments.
Epitalon
Epitalon has no FDA approval status and sits on the 503A Category 2 list. It is not approved for clinical use in the US. Northline tracks regulatory developments globally.
MOTS-C
MOTS-C is a novel research peptide with no FDA approval and no established compounding status. It falls outside current 503A eligible lists. Northline monitors emerging regulatory frameworks.
Kisspeptin-10
Kisspeptin-10 is not FDA-approved and is on the 503A Category 2 list. Clinical use is limited to research settings. Northline does not prescribe and monitors reclassification.
AOD-9604
AOD-9604 received FDA GRAS status in 2014 as a food ingredient but has no drug approval. It is on the 503A Category 2 list for injectable compounding. Northline does not prescribe and monitors regulatory status.

Those watchlist entries are useful for search and education, but they also need restraint. A watchlist page should help people understand status, not imply that reclassification or future access is guaranteed.

How Northline should evaluate peptide pages

Every peptide page should answer four questions clearly: what the compound is, what users usually look for it to do, whether Northline prescribes it today, and what regulatory or sourcing limits apply. Without those four answers, peptide content turns into hype very quickly.

This is also where internal linking matters. Users coming from a generic peptide query often need to branch into safety, legal status, a specific compound page, or a general explanation of how Northline decides what belongs in the formulary.

Why this topic matters for SEO

Peptide-related search behavior is fragmented. Some users search a compound name directly. Others search broad terms like peptide therapy, recovery peptides, or peptide safety. Northline needs both the hub and the leaf pages to compete in that landscape.

The hub page should frame the category responsibly. The individual compound pages should answer the deeper question. Together they create a cleaner crawl graph and a more credible user path.
