Question 1

Are PeptOnline products for human consumption?

Accepted Answer

No. All PeptOnline products are supplied strictly for in-vitro and laboratory research purposes only. They are not medicinal products, are not licensed for human or veterinary administration, and must not be consumed, injected, or otherwise administered to humans or animals. By purchasing, you confirm that you are a qualified researcher and will handle these materials exclusively in an appropriate laboratory environment.

Question 2

What does 'research use only' mean?

Accepted Answer

'Research use only' (RUO) means our peptides are intended for laboratory investigation, analytical reference, and controlled scientific study only. They are not intended for therapeutic, diagnostic, or prophylactic use. Any application outside a certified research laboratory is strictly prohibited and violates our terms of sale.

Question 3

How should I store my research peptide pens?

Accepted Answer

All PeptOnline pre-loaded pens must be refrigerated at 2–8°C immediately upon receipt. Protect from direct light and do not freeze. Freezing can degrade peptide integrity and compromise research outcomes. If a pen has been exposed to temperatures outside this range for an extended period, do not use it for critical research—contact us for a replacement.

Question 4

What safety equipment should I use when handling peptides?

Accepted Answer

Always wear nitrile gloves, safety goggles, and a lab coat when handling peptide compounds. Work in a fume hood or well-ventilated laboratory area. Avoid inhalation, skin contact, and eye exposure. Dispose of any unused material and packaging in accordance with your institution's hazardous-waste protocols. Do not eat, drink, or apply cosmetics while handling research chemicals.

Question 5

What is the origin of PeptOnline peptides?

Accepted Answer

Every PeptOnline peptide is synthesised, blended (where applicable), and assembled in the United Kingdom under controlled laboratory conditions. We do not import raw materials from unverified sources. Each batch is released only after independent HPLC (≥99% purity), mass-spectrometry verification, and endotoxin testing.

Question 6

Can I travel with research peptide pens?

Accepted Answer

Research peptides are not medicines and should not be transported across borders without appropriate documentation and customs declarations. If you need to move materials between laboratories, consult your institution's biosafety officer and the relevant customs authority. PeptOnline is not responsible for items seized or detained during transit.

Question 7

What do I do if a pen leaks or is damaged in transit?

Accepted Answer

Do not attempt to open, repair, or use a damaged or leaking pen. Place it in a sealed biohazard bag and store it refrigerated. Contact PeptOnline within 48 hours of delivery with photographic evidence. We will replace damaged goods at no cost, provided the damage is reported promptly and the product has not been tampered with.

Question 8

How much is delivered per click on each pen?

Accepted Answer

Retatrutide (30 mg pen): each click delivers 0.1 mg, so 10 clicks equals 1 mg, with 30 mg total per pen. Wolverine Recovery (30 mg pen — BPC-157 10 mg, KPV 10 mg, TB-500 10 mg): each click delivers 0.1 mg, so 10 clicks equals 1 mg, with 30 mg total per pen. NAD+ (500 mg vial): each click delivers 1.66 mg, so 30 clicks equals the standard 50 mg increment, with 500 mg total per vial. Always attach a fresh needle and prime the pen as directed before dialling. For research purposes only.

Question 9

How long are peptide pens stable once received?

Accepted Answer

When stored correctly at 2–8°C and protected from light, unopened PeptOnline pens remain stable for the duration indicated on the batch label—typically 12–24 months from synthesis date. Do not use pens past their labelled expiry date. Stability data is batch-specific and available on request.
