Your questions, answered
How do I know which amount per vial to choose?
The amount indicated in milligrams represents the quantity of product contained in the vial; it does not, by itself, define the amount a person should use. A larger presentation may be useful when the plan requires more product or greater flexibility, but it does not imply greater efficacy. At LYRN, the choice should be based on the objective, the intended duration, and an assessment of the specific case.
What is the difference between an individual peptide, a blend, and a stack?
A single peptide contains only one compound. A blend mixes several compounds within the same vial, which simplifies use but fixes the ratio between them. A stack combines products in separate vials, allowing each component to be adjusted independently.
Can I combine this product with other peptides?
Some products have complementary mechanisms and appear together in specific blends or stacks. Even so,
combining more tools does not always improve the outcome and can make it difficult to determine what is working.
The combination should address a specific goal and be reviewed within the individual’s overall context.
How should it be stored before and after preparation?
The technical guide indicates that lyophilized vials must be kept refrigerated and protected from heat and direct light. Once reconstituted with bacteriostatic water, they must be stored refrigerated, and their stability is more limited. The product label and specific instructions must always take precedence.
What does it mean for a product to have a purity of over 99%?
Purity indicates the proportion of the analyzed material that corresponds to the target compound versus impurities or synthesis by-products. High purity is a key indicator of quality, but it is not the only criterion; identity, actual quantity, sterility, stability, and batch traceability are also important.
How are the product's quality and composition verified?
The primary reference is the Certificate of Analysis (COA), ideally supported by independent analytical testing. The COA should help verify identity, purity, and—where applicable—the quantity of each component. For blends, it is particularly important to verify the exact composition rather than just the total weight of the vial.
What exactly does my order include?
The order includes the product and the quantity selected on the product page. Bacteriostatic water, auxiliary materials, additional packaging, or accompanying services should only be considered included if expressly indicated during the purchase process. The page must display the exact contents before the order is confirmed.
How long does shipping take?
The technical documents used for this guide do not specify a single delivery timeframe. Delivery time depends on the destination country, order preparation, the carrier, and customs checks. The website must display an up-to-date estimate for each region and clarify that international delivery times may vary.
Do I need an assessment before choosing a product?
This is advisable—particularly for metabolic or hormonal products, complex blends, or cases with a relevant medical history. An assessment makes it possible to verify whether the tool aligns with the objective and whether a simpler option exists. LYRN’s approach is to understand the context first and select the product afterward.
Why is a larger amount per vial not always the best option?
Because the result does not depend on purchasing the vial with the highest milligram count, but rather on the product and format aligning with the plan. A larger quantity can add cost or complexity, or result in excess product. With peptides, “more” does not automatically mean “better”; it simply means a larger quantity is available.
