leanlab.la
Link authority for leanlab.la (registrable domain: leanlab.la) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Web-graph authority (0-100)
Domain scores measure leanlab.la as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname leanlab.la. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

We provide a personalized nutrition guide and lifestyle recommendations with every program."}},{"@type":"Question","name":"How long do I need to stay on the medication?","acceptedAnswer":{"@type":"Answer","text":"Most patients see the best results with a 6–12 month commitment.

It may be ideal for patients who haven't achieved their goals on other medications."}},{"@type":"Question","name":"Do you offer compounded GLP-1 medications?","acceptedAnswer":{"@type":"Answer","text":"Yes. We work with licensed compounding pharmacies to provide high-quality, affordable alternatives to brand-name medications.

Multi-month programs are prepaid and non-refundable after the first visit, but we work with patients on a case-by-case basis if circumstances change."}},{"@type":"Question","name":"Do you accept insurance?","acceptedAnswer":{"@type":"Answer","text":"We are a cash-pay clinic and do not bill insurance directly. However, many patients use HSA/FSA accounts. We can provide itemized receipts for potential reimbursement depending on your plan."}},{"@type":"Question","name":"Do you offer payment plans?","acceptedAnswer":{"@type":"Answer","text":"Yes.

We review your health history before every session."}},{"@type":"Question","name":"What are peptides and how do they work?","acceptedAnswer":{"@type":"Answer","text":"Peptides are short chains of amino acids that act as signaling molecules in the body. They can stimulate growth hormone release, accelerate healing, improve cognitive function, and support fat loss — depending on the specific peptide."}},{"@type":"Question","name":"What peptides do you offer?","acceptedAnswer":{"@type":"Answer","text":"We offer 25+ peptides organized by goal: fat loss (AOD-9604, CJC/Ipamorelin), muscle & recovery (BPC-157, TB-500), cognitive (Semax, Selank), anti-aging (Epithalon, GHK-Cu), and more. Browse by goal on our Peptides page."}},{"@type":"Question","name":"What is BHRT and who is it for?","acceptedAnswer":{"@type":"Answer","text":"Bioidentical Hormone Replacement Therapy (BHRT) restores optimal hormone levels using hormones that are molecularly identical to those your body produces. It's available for women (estrogen/progesterone) and men (testosterone/TRT)."}},{"@type":"Question","name":"What is Enclomiphene and how is it different from TRT?","acceptedAnswer":{"@type":"Answer","text":"Enclomiphene stimulates your body's own testosterone production rather than replacing it externally. It's a great option for men who want to optimize testosterone while preserving fertility and natural hormonal function."}},{"@type":"Question","name":"How do I know if I have low testosterone?","acceptedAnswer":{"@type":"Answer","text":"Common symptoms include fatigue, low libido, brain fog, mood changes, and difficulty building muscle.

Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.
A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.
Backlink counts
Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for leanlab.la and domain-level for leanlab.la with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
