Questions

FAQ

Yes. Research peptides are legal to purchase in the UK for legitimate research purposes. They are not licensed medicines and are sold strictly as research chemicals. It is the buyer's responsibility to ensure compliance with all applicable laws in their jurisdiction. All purchases from Clyde Peptides are made under the explicit understanding that products are for in-vitro research use only and are not intended for human or animal consumption.
Use our Reconstitution Calculator above for exact measurements. As a general guide: use bacteriostatic water (bac water), inject it slowly down the inside of the vial wall, do not shake — swirl gently. Store reconstituted peptides refrigerated at 2–8°C and use within 28 days. Lyophilised (unmixed) vials should be stored in a freezer until needed.
It depends on how much bac water you added. Use the Reconstitution Calculator for your exact figures. As an example: 30mg peptide mixed with 3ml bac water = 10mg/ml. On a standard 60-unit pen, 1 click = 0.0167ml = 0.167mg. So 1mg = 6 clicks. Always double-check using the calculator above.
All orders are dispatched in plain, discreet outer packaging with no branding, company name, or product descriptions visible externally. Vials are individually sealed and protected. The sender name on the label will be a neutral business name.
UK orders are dispatched within 48 hours of payment confirmation and typically arrive within 2–3 working days via tracked courier. International orders take 5–7 working days. A tracking number will be emailed to you upon dispatch.
Every batch is independently purity tested by Janoshik Laboratory using HPLC analysis before we stock it. The test confirms compound identity and purity percentage.
