Frequently asked questions
Everything you need to know about Klarovel, peptide protocols, and how the platform works.
Answers maintained by the Klarovel team, last updated 26 September 2026. Questions or corrections: support@klarovel.com. How every protocol is checked.
Klarovel is a research-first protocol-intelligence platform for adults exploring peptide therapy. The questions below cover what the engine does and does not do, how cycles are structured, what bloodwork unlocks, how pricing works, and where Klarovel's role begins and ends. Every protocol is screened against contraindications, drug interactions, biomarker thresholds, and current regulatory status before any recommendation reaches the user. Klarovel does not sell, source, or fulfil peptides; obtaining them is the user's own responsibility. If your specific question is not answered below, the health assessment is the fastest way to surface what the engine would recommend for your context.
What are peptides?
Peptides are short chains of amino acids that act as signaling molecules in the body. Different peptides trigger different biological responses, from stimulating growth hormone release to accelerating tissue repair, improving sleep quality, or supporting immune function. They are used in longevity medicine, sports recovery, cognitive enhancement, and anti-aging protocols.
How does Klarovel create my protocol?
Klarovel uses a deterministic rules engine (not a chatbot) to evaluate your health profile. The engine checks for contraindications with your health conditions and medications, matches peptides to your specific goals, sets dose bounds from your profile (refined by biomarkers when you have blood work), designs cycling schedules, and generates monitoring plans. Its rules are covered by automated tests that run on every change. An AI then translates this structured output into a clear, actionable protocol report.
How is Klarovel different from a peptide telehealth clinic?
Most telehealth peptide clinics are sales channels for a small set of compounds, and the consultation is a short form. Klarovel does not sell peptides at all, and earns nothing on what you buy elsewhere, so there is no compound we have a commercial reason to steer you toward. Our deterministic engine generates a protocol based on your full health profile, goals, contraindications, drug interactions, and (optionally) bloodwork. We are not in the supply chain.
Do I need bloodwork?
Bloodwork is strongly recommended but not required for your first protocol. Without biomarker data, the engine uses conservative standard dosing based on your experience level and body weight. With bloodwork, your doses are precisely calibrated to your IGF-1, metabolic markers, hormonal profile, and more. We accept blood test results from any lab worldwide.
Can I upload my own bloodwork?
Yes. Bloodwork is optional but it makes the protocol significantly more precise. The OCR engine reads PDF lab reports from Norwegian and most international labs. Key biomarkers like IGF-1, HbA1c, fasting glucose, fasting insulin, lipids, TSH, and testosterone modify dose envelopes and unlock or block specific peptides.
Is my data safe?
Your health data is stored in a GDPR-compliant database with row-level security. Your data is never shared with third parties. All connections are encrypted. We take health data privacy seriously. It is a fundamental requirement for a platform handling sensitive health and wellness information.
Will my doctor or GP see this?
No, unless you choose to share it. Klarovel does not contact your healthcare providers. Your protocol PDF is yours to bring to a GP, endocrinologist, or sports physician for a second clinical opinion before starting a cycle, which we genuinely recommend.
Does Klarovel sell peptides?
No. Klarovel does not sell, distribute, or manufacture peptides, does not refer you to suppliers, and takes no commission on anything you buy anywhere. We are a protocol intelligence platform: we help you design a protocol from your health data, and the protocol is the only thing we charge for. The protocol is the product, not the peptides.
Does Klarovel sell or supply the peptides?
No. Klarovel does not sell, source, or fulfil peptides. Klarovel curates the protocol layer (dose math, cycling, titration, monitoring) and the assessment layer (questionnaire, biomarker review); where you obtain anything is your own arrangement, and Klarovel takes no commission on it. Pen versus vial preference is captured in the assessment so the protocol matches what you're comfortable injecting.
Does Klarovel ship peptides?
No. Nothing is shipped from Klarovel, because nothing is sold by Klarovel. There is no order flow, no supplier we send you to, and no delivery window for us to quote. Sourcing is entirely your own arrangement, and it happens outside this platform.
What am I paying for?
Your protocol, and only your protocol. $99 one time covers the assessment, the engine, your personalized 12-week protocol, and the AI assistant, lab upload and tracking while it runs. Each renewal is another $99. You never pay Klarovel for a peptide, because Klarovel does not sell them, and we take no commission on anything you buy anywhere else.
How much does it cost?
$99 one time per protocol. Previously $179 a year. There is no subscription and no monthly plan: a protocol runs for 12 weeks, and each renewal (your next cycle) is another $99, bought only if you want it. The price covers an engine-screened peptide protocol built from your health profile, dosing that sharpens when you add blood work, cycle 2+ recalibration when you renew, and the AI protocol assistant, lab upload and tracking while the protocol runs. Peptides themselves are not included, and Klarovel does not sell, source, or fulfil them.
Is there a subscription to cancel?
No. Each protocol is a one-time $99 purchase, so nothing renews automatically and there is nothing to cancel. You buy the next cycle only if you want it. Your protocols, bloodwork, and conversation history stay in your account, and the data export option in account settings lets you take a copy with you at any time.
Which peptides does Klarovel cover?
The catalog spans GH-axis secretagogues (CJC-1295, ipamorelin, tesamorelin, sermorelin, MK-677), tissue-healing peptides (BPC-157, TB-500, GHK-Cu), GLP-1 class agents (semaglutide, tirzepatide, retatrutide), cognitive peptides (semax, selank, dihexa, cerebrolysin), and longevity-cluster compounds (epitalon, NAD+, DSIP, thymosin alpha-1). Each catalog entry carries a research-grade evidence anchor, dose ranges from published protocols, and a contraindication profile the engine consults before any recommendation is generated.
How do I know if a peptide is the right match for my goals?
The engine scores every catalog peptide against your goals on seven dimensions: goal relevance, safety clearance, biomarker alignment, experience tier, delivery preference, evidence tier, and (for cycle 2+) continuation history. You see the top-scored matches in your protocol, plus overflow candidates the engine considered but held back for a future cycle.
What's the difference between GLP-1 peptides and traditional weight-loss drugs?
GLP-1 peptides like semaglutide, tirzepatide, and retatrutide are themselves the active ingredient in the major prescription weight-loss medications (Wegovy, Zepbound, Mounjaro). They work by mimicking the body's own GLP-1 hormone, slowing gastric emptying and increasing satiety. They are not stimulants, not classical appetite suppressants, and not metabolism boosters.
Can I use this alongside TRT/HRT?
Yes. The health assessment asks about current hormone therapies, and the rules engine accounts for concurrent TRT, HRT, and other hormonal treatments when selecting peptides and calculating doses. Certain peptide-hormone interactions are flagged automatically.
Can I use this if I'm on metformin, SSRIs, or blood thinners?
The questionnaire asks for all current medications. The engine checks documented drug interactions, such as GLP-1 dose adjustments alongside insulin or sulfonylureas, and monitoring rules for SSRIs combined with serotonergic peptides. It either flags the interaction in caution notes or blocks the peptide outright. You see exactly which peptides were blocked and why.
What if I have a medical condition?
The rules engine screens for 10+ health conditions including diabetes, heart disease, cancer history, autoimmune conditions, thyroid disorders, kidney and liver disease, and pregnancy. Conditions can result in peptides being blocked entirely, flagged with caution warnings, or having their doses reduced. The engine prioritizes your safety above all else.
Do I need to inject myself?
Most peptides are subcutaneous injections with a small needle, similar to insulin. If you prefer not to handle vials and syringes, the protocol prioritises peptides available as prefilled pens (semaglutide, tirzepatide, and some GH-axis options). Your knowledge level and form preference are captured in the questionnaire and feed directly into protocol design.
What happens if I miss a dose?
Missed-dose rules are peptide-specific and live in your protocol's daily plan. The short version: for daily peptides under 24 hours late, take it when you remember; if longer, skip it and resume the schedule. For weekly peptides (most GLP-1s), take it within 48 hours of the missed dose or skip and continue the following week. Never double up.
What if a peptide on my protocol doesn't suit me?
Side effects and tolerance are tracked through the side-effect log. At the end of the cycle, the follow-up assessment captures what worked, what did not, and which goals have shifted. The engine uses this to adjust cycle 2: escalate the dose if you responded well, reduce or swap the peptide if not.
How long does a typical cycle last?
Most GH-axis and tissue-healing protocols run on an 8 to 12 week cycle with a 4 week off-period, sometimes followed by a tapered re-entry. GLP-1 class agents (semaglutide, tirzepatide, retatrutide) are continuous-use because cycling them off causes weight regain; the engine schedules a label-driven titration ladder instead of an off-cycle. The protocol document includes a calendar view so you can see every dose, every taper week, and every blood-test checkpoint at a glance.
What happens after my first cycle?
When your active cycle ends, the platform prompts a follow-up assessment covering compliance, side effects, goals achieved, and ideally a fresh bloodwork pull to compare against baseline. The engine then runs cycle 2+ logic: dose escalation (starting to standard to advanced) if cycle 1 was well tolerated and on-target, dose hold if response was partial, or peptide rotation if biomarkers indicate a different lever is more useful. The renewal protocol is generated on the same engine with the new context layered in.
Can I change my goals between cycles?
Yes. The follow-up assessment between cycles lets you update goals, current symptoms, lifestyle, and bloodwork. The cycle 2 engine run weighs continuation candidates against new candidates that better match the updated profile.
Where is Klarovel available?
Yes. Klarovel is a globally accessible platform; the protocol engine, questionnaire, biomarker analysis, and AI translation layer are not locked to any one country. Regulatory status varies by jurisdiction (FDA in the US, for example), and protocols state it plainly where it matters. The platform itself supports English-first with Norwegian as a fallback locale, and additional locales are added based on user demand.
