Keep the material identity alongside the size
A presentation is the labelled quantity and composition of the material offered. Match the compound name, relevant sequence/form and presentation before comparing catalogue records. A shared milligram figure does not make two products equivalent.
Use the currently configured product-page selector and the same selected presentation in your cart. Confirm availability and the final total with the team.
Total blend mass versus component mass
For a label stating 5 mg BPC-157 + 5 mg TB-500, the total labelled peptide mass is 10 mg. A 20 mg total label does not, by itself, tell you the split between constituents. Ask for the component amounts instead of assuming a ratio.
These are label-reading examples, not results from testing our batches. A blend certificate should be read for the identified constituents and the measurements actually reported.
Watch decimal values and units
One milligram equals 1,000 micrograms. A 0.1 mg presentation is one tenth of a 1 mg presentation. Millilitres are a volume unit and cannot be compared with milligrams without a stated concentration.
The quantity on a material label is not an administration instruction. This guide explains catalogue units, not how to prepare or use a material.
CJC-1295 DAC versus No DAC
No DAC and without DAC are equivalent catalogue descriptions here. They are not the same as a long-acting DAC-linked CJC-1295 material. Keep the form explicit in the product record and in any literature comparison.
The long-acting study by Teichman and colleagues reports endocrine responses for the material studied there. Its duration cannot be assigned to a No DAC product simply because both names include CJC-1295.
Common blend labels explained
BPC-157 + TB-500 (often called the Wolverine Stack) is listed as 10 mg total: 5 mg BPC-157 + 5 mg TB-500. CJC-1295 No DAC + Ipamorelin is listed as 10 mg total: 5 mg of each. GLOW combines BPC-157, TB-500 and GHK-Cu, and KLOW adds KPV as a fourth constituent.
For GLOW and KLOW, read the stated milligrams for every constituent on the label or product record. Names do not standardise the split between suppliers.
Comparing prices fairly
Divide the INR price by the labelled milligrams of the compound you need. For a blend, divide by the amount of each constituent. A 10 mg two-component blend contains 5 mg of each compound, so its price per milligram of either compound is double its price per milligram of total mass.
Product pages on The Peptide Co. show current INR prices for each listed presentation. Delivery is ₹150 standard (3–5 days) or ₹350 express (2–3 days), with cash on delivery ₹150 extra, so include delivery when comparing totals.
Reconstitution arithmetic for single vials and blends
Concentration equals the labelled peptide mass divided by the diluent volume. A 10 mg single vial with 2 mL of diluent gives 5 mg/mL. For a 5 mg + 5 mg blend in 2 mL, each constituent is at 2.5 mg/mL.
The peptide calculator performs this conversion and shows the corresponding U-100 or U-40 syringe units for laboratory measurement. It is arithmetic for research preparation, not administration guidance.
Vial size, fill and labelling
Vial glass size and the visual volume of lyophilized powder vary between batches and do not indicate the amount of peptide. Rely on the labelled mass and the batch documentation, not on how full a vial looks.
Check that the cap, seal and label are intact and that the label states the compound, amount, lot and research-use-only wording.
When to choose single vials
Single vials suit protocols that need to vary or record each compound independently, or that need only one constituent. Blends suit protocols that require a fixed ratio of constituents from one batch. Our comparison guides cover BPC-157 vs TB-500 vs the Wolverine Stack, KLOW vs GLOW and CJC-1295 + Ipamorelin blend vs single vials.
Worked example: comparing a blend with single vials
Suppose a protocol needs equal amounts of BPC-157 and TB-500. Option A is one 10 mg BPC-157 + TB-500 blend (5 mg + 5 mg). Option B is one 10 mg BPC-157 vial plus one 10 mg TB-500 vial. Option B supplies twice as much of each compound in two separate lots; option A supplies both compounds in one lot at a fixed 1:1 ratio.
To compare cost, divide each option’s INR total by the milligrams of each compound it supplies. Then add delivery once per order, not once per vial, because a single order ships together.
Labels that need a question
Ask the supplier before ordering when a label shows only a blend name with no milligrams, a total with no component split, a size that differs from the product page, units that mix mg and mcg inconsistently, or no lot identifier. These are documentation gaps, not proof of a problem, but they make the material difficult to verify.
Recording the exact label wording in your research notes helps when you reorder, compare a new lot or discuss a purity concern with the supplier.
Micrograms, milligrams and international units
Some materials are labelled in micrograms (mcg) and others in milligrams (mg); 1 mg equals 1,000 mcg. A few materials, such as some hormone-related products, may be labelled in international units (IU), which are defined by biological activity rather than mass and cannot be converted to milligrams without a compound-specific factor.
When a label uses IU, do not compare it directly with a milligram label. Ask for the stated mass or the conversion basis used for the batch.
Bacteriostatic water and other diluents
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol as a preservative, commonly used as a laboratory diluent for reconstituting lyophilized peptides. The Peptide Co. lists a 10 mL BAC water presentation alongside its peptides.
The volume of diluent you choose changes the concentration, not the total mass of peptide in the vial. Record the diluent and volume with the batch identifier.
Create a like-for-like comparison
Make a table with the full material name, chemical form, constituent amounts, vial count and total INR cost. Keep delivery charges separate until the complete order total is known.
If the seller lists only a combined mass, mark constituent amounts as unknown. Do not treat an assumed split as a product specification.
A protocol needs more than an attractive label
A blend can add experimental variables that a single-compound protocol does not contain. A material form change can also affect how a cited experiment relates to the sample. Record the reason for selecting a presentation before comparing prices.
Keep the label, certificate and quotation aligned. If one record says No DAC and another says DAC, seek clarification rather than accepting the shared CJC name as sufficient.
Preserve the selected size through checkout
Review the cart line after selecting a presentation: the size, price and quantity should match the product controls. The WhatsApp enquiry carries the requested items, while the final stock and delivery confirmation come from the team.
If a listed presentation changes between visits, use the current product page and request a fresh quotation. A cached screenshot is not a current stock commitment.
