Peptide questions, answered plainly
Dosing maths, syringe units, mixing, storage life, GLP-1 titration, vendor quality and how to get 20% off your order. Every answer is educational, never medical advice.
Dosage Calculator
What does the Peptide Clarity dosage calculator do?
It converts a vial size and the amount of bacteriostatic water you add into the exact number of insulin syringe units for your target dose. You pick the peptide, enter the vial strength in milligrams, enter the water volume in millilitres, then enter the dose you want in micrograms or milligrams. The calculator returns the concentration and the unit mark to draw to on a standard U-100 syringe.
Is the peptide calculator free to use?
Yes. The calculator is free. You confirm your email and date of birth once to show you are 21 or older, and then you have access. There is no card required and no trial period.
How do I sign up for the calculator?
Open the calculator page, enter your email and date of birth to confirm you are 21 or older, and you are in. Creating a free account additionally saves your peptides, reconstitution records, protocol calendar and dose history between visits.
How do I calculate insulin syringe units for a peptide dose?
Divide the vial strength by the water volume to get concentration per millilitre, then divide your target dose by that concentration to get millilitres, then multiply by 100 to get units on a U-100 insulin syringe. Example: a 5 mg vial with 2 ml of water is 2.5 mg per ml, so a 250 mcg dose is 0.1 ml, which is 10 units. The calculator does this for you and shows the working.
How much bacteriostatic water should I add to a vial?
There is no single correct volume. More water means a larger, easier to read draw on the syringe. Less water means a smaller injection volume. Common choices are 1 ml, 2 ml or 3 ml per vial. Run a couple of options through the calculator and pick the one that puts your usual dose on a clean, easy to read unit mark.
Does the calculator work on a phone?
Yes. It is built to work on a phone screen, and you can add Peptide Clarity to your home screen from the install page so it opens like an app.
Can I track doses and reconstitution dates too?
Yes. A free account gives you a fridge log with reconstitution dates and expiry tracking, a protocol calendar with dose logging, injection site rotation, weight and measurement tracking, and progress photos.
Discount Code & Buying
Is there a discount code for peptides?
Yes. Use code VIP20 at SuperNovaSciences.com for 20% off your order. It works on the whole site, and you can reuse it on repeat orders.
How do I use the VIP20 code?
Add your items at SuperNovaSciences.com, then type VIP20 into the discount or promo field at checkout. The 20% comes off before you pay. If the field does not appear, look for a "have a code?" link on the payment step.
Does the VIP20 code expire?
It is an ongoing code for Peptide Clarity readers rather than a limited-time sale. If it ever stops working, ask us and we will confirm the current code.
How do I tell a good peptide vendor from a bad one?
Ask for batch-specific certificates of analysis from an independent lab, covering both identity and purity. Be wary of vendors selling pre-mixed ready-to-inject solutions, vendors making medical claims about treating disease, and vendors who cannot show recent testing. Consistent lot numbering and clear storage instructions are good signs.
What supplies do I need besides the peptide?
Bacteriostatic water, alcohol swabs, insulin syringes in the size you prefer, a sharps container, and fridge space. Our supplies page lists the exact items we use with links.
Storage & Handling
How should I store peptide vials?
Keep lyophilised (powder) vials in the fridge, or the freezer for long storage, away from light. Once mixed with bacteriostatic water, keep the vial refrigerated at roughly 2 to 8 degrees Celsius and avoid shaking it.
How long does a peptide last after mixing?
Most reconstituted peptides are considered usable for about 28 to 30 days refrigerated when mixed with bacteriostatic water, which contains a preservative. Plain sterile water has no preservative and is a much shorter window. Stability varies by peptide, so log your mix date. The fridge tracker does that for you.
Can peptides go bad?
Yes. Heat, light, repeated freeze-thaw cycles and vigorous shaking all degrade peptides. Cloudiness, visible particles or a colour change after mixing mean the vial should not be used.
How do I mix a peptide vial correctly?
Swab both stoppers, draw your bacteriostatic water, and aim the stream slowly down the inside wall of the vial rather than straight onto the powder. Let it dissolve on its own or swirl gently. Never shake.
GLP-1 & Metabolic
What is the difference between semaglutide and tirzepatide?
Semaglutide acts on the GLP-1 receptor. Tirzepatide acts on both GLP-1 and GIP receptors, and in head to head trials produced larger average weight reduction. Tirzepatide also tends to need a slower titration for tolerability.
Why do GLP-1 doses start so low?
Nausea, reflux and constipation are dose related. Starting low and stepping up every four weeks gives the gut time to adapt, which is why almost every protocol uses a titration schedule rather than jumping to a maintenance dose.
How do I avoid losing muscle on a GLP-1?
Keep protein high, roughly 1.2 to 1.6 grams per kilogram of body weight per day for most adults, train against resistance two to three times a week, and avoid very aggressive calorie cuts. Weight dropping fast with no strength work usually means lean mass is going with it.
What should women over 50 know about tirzepatide?
Muscle and bone loss accelerate after menopause, so protein intake, resistance training and bone health matter more than the number on the scale. Hydration, fibre and slower dose increases also reduce the gut side effects that are common in this group. We have a full article on this in the blog.
Safety & Legal
Is Peptide Clarity medical advice?
No. Everything here is educational. We are not prescribing, diagnosing or treating anything. Talk to a licensed healthcare provider before starting any peptide, prescription medication or injectable.
Do I have to be 21 to use this site?
Yes. Our tools and articles are restricted to adults 21 and older. You confirm your date of birth once before the tools and articles open.
Are peptides legal?
It depends on the compound and your country. Many research peptides are sold for laboratory research only and are not approved for human use. Some, like semaglutide and tirzepatide, are approved medications that require a prescription. Check your local rules and speak with a clinician.
Why is retatrutide content restricted here?
Retatrutide is investigational and not approved for human use, so our coverage of it is limited. Some articles are shortened, published without dosing detail, or removed, and availability can change.
About Peptide Clarity
How long has Peptide Clarity been around?
Peptide Clarity started in the fall of 2024, first as a dosage calculator and a handful of notes, then as a full library. The peptide space keeps moving, so the site keeps growing with it: new compounds, updated research, and new tools added as we learn them.
What is Peptide Clarity?
Peptide Clarity is a free peptide education site with a dosage calculator, reconstitution and fridge tracking, a protocol calendar, an AI assistant, and a library of plain-English articles. It is built for people who want the maths done correctly and the research explained without hype.
Does Peptide Clarity sell peptides?
No. We do not sell peptides. We point to vendors we have used, and we earn a commission on some links, including the SuperNovaSciences code VIP20 and Amazon supply links.
Can I ask a question and get an answer?
Yes. Use the Ask a Question form. Selected questions get answered in full articles, and you can also book a private consultation through the coaching page.
Is there a custom GPT for peptide questions?
Yes. The Peptide Clarity Quick Info Sheet GPT is available in ChatGPT and is linked from the top of every page.
