FAQ
Got questions? Here's a list of the most common questions we get about peptides. If you have any other questions, feel free to contact us directly.
What makes your peptides different from others?
We offer peptides sourced from Europe’s only EMA-regulated tissue bank and GMP-certified facility. They are a certified and regulated lab - everything they do is tested and to the quality and concentrations they state. They are actually the testing lab to satisfy regulators so we are guaranteed they cannot cut any corners.
Typically, with other injectable peptides in the market, you would have to buy 5mg of powder separately to mix yourself with water, whereas we provide a 15mg vial (3ml volume) ready to inject—which is three times the amount upfront.
Ours require no mixing, are not made in China or India, and come from a high-quality, accredited lab in Europe. It also comes in an insulin pen-style with a tiny needle, ready to inject. Our pens come with about 30-40 doses in each vial so depending on the frequency you are using them, they can last for months. Our peptides can last up to 2 years either in or out of the fridge as they are great for travel as well. Each pen comes with 3 attachable needle heads - each good for up to 10 pricks. You can purchase more in bulk at your nearest Shoppers Drug Mart.
Summary of our product:
1) Our Peptides are sourced directly from Europe’s only EMA-regulated tissue bank and GMP-certified facility — the same source trusted by clinics and compounding pharmacies worldwide.
2) No fillers / preservatives/ hidden additives and guaranteed potency/shelf stable for 2years when refrigerated.
3) Our peptides are pharmaceutical-grade, pre-mixed sterile vials (no powders) and ready to inject in a pen format.
4) purity 99% and manufactured in-house at the lab.
5) volume is 3x more than normal so ours last 4-6 weeks on a cycle.
Are your peptides safe and tested?
Absolutely. Every vial is lab-certified, batch tested, and produced in an EU-regulated cleanroom environment. There are no preservatives or contaminants, and each batch comes with full documentation. This is a major step above unregulated peptides from China, India, or Taiwan, where safety and quality controls are often lacking or non-existent.
Do I need to mix these peptides myself?
No. Our peptides come pre-mixed and ready to use. No measuring, mixing, or handling raw powders. Just store in the fridge and use as directed. This reduces the risk of contamination or dosing errors, and it means you get maximum efficacy without the hassle.
What conditions can peptides help treat?
Peptides are used for a wide array of indications including:
* Anti-aging & longevity (e.g. Epitalon, MOTS-c)
* Tissue repair and regeneration (e.g. BPC-157, TB-500)
* Metabolic disorders (e.g. MOTS-c, FGF21)
* Sexual dysfunction (e.g. PT-141)
* Immune modulation (e.g. Thymulin, Thymosin alpha-1)
* Neurodegenerative support (e.g. Cerebrolysin, Selank)
How are peptides administered?
Most therapeutic peptides are administered via subcutaneous or intramuscular injections. Some formulations are available for topical or intranasal use depending on the peptide's structure and intended function.
Are peptide therapies safe?
Yes, when manufactured under GMP conditions and administered correctly, peptides are generally safe with low immunogenicity. Augmented peptides from RBT or Neo7Bioscience are specifically engineered to be more stable, less toxic, and longer-lasting.
How long before I see results from peptide therapy?
Depending on the peptide and the condition being treated, most users begin to see effects within 2–4 weeks, with optimal results often achieved after 8–12 weeks. Protocols typically involve 3 injections per week over a 12-week period followed by a 3-week pause.
Can peptides help with anti-aging?
Yes. Peptides such as Epitalon, GHK-Cu, MOTS-c, and Thymosin beta-4 have demonstrated anti-aging benefits including telomere extension, improved mitochondrial function, reduced inflammation, and enhanced cellular repair.
Are the peptides natural or synthetic?
Most therapeutic peptides are synthetic analogues of naturally occurring peptides. They are custom-designed and enhanced (e.g., PEGylated or linked to cell-delivery scaffolds) for increased potency, stability, and bioavailability.
How do I know which peptide is right for me?
Peptide selection is based on individual biomarker profiles, genetic data, clinical history, and specific health goals.
Do peptides have any side effects?
Side effects are usually minimal and may include injection site irritation, mild flu-like symptoms, or temporary hormonal fluctuations. Proper dose escalation helps mitigate risks.
Are peptide therapies legal and regulated?
Peptides used in clinical settings must comply with national and EU regulatory frameworks (such as EMA for ATMPs and peptide therapies). At Longevity Diva, all peptide treatments are produced in GMP-certified facilities, ensuring high standards of safety and quality.
