Question 1

What purity level are your peptides?

Accepted Answer

≥99%, measured by HPLC. The actual number for the batch you receive is on the CoA, along with molecular weight and identity confirmation.

Question 2

Where do your compounds come from?

Accepted Answer

We source from accredited UK and European facilities that operate under ISO 17025 conditions using Fmoc SPPS. Every batch is independently tested before we stock it.

Question 3

How do I obtain a Certificate of Analysis (CoA)?

Accepted Answer

Email info@buy-peptidesuk.com with your order number. We'll send the batch CoA back, usually same day.

Question 4

What is the difference between a peptide and a SARM?

Accepted Answer

Peptides are short amino acid chains that bind to receptors and trigger signalling responses. SARMs are small synthetic molecules that bind androgen receptors but only act on certain tissues. Both are research-only here.

Question 5

What does 'lyophilised' mean?

Accepted Answer

Freeze-dried. The compound is frozen under vacuum so all the water sublimes off, leaving a stable white powder that holds up much better in long-term −20°C storage than a liquid would.

Question 6

What payment methods do you accept?

Accepted Answer

UK bank transfer (BACS) and card via a secure payment link issued with your order. Bank details show up at checkout if you pick that option.

Question 7

How quickly will my order be dispatched?

Accepted Answer

Order before 2PM on a working day and it goes out the same day. After 2PM or on weekends, it ships the next working day. Tracking number lands in your email as soon as it's collected.

Question 8

Can I place a bulk or wholesale order?

Accepted Answer

Yes - 10+ vials of the same compound qualifies for volume pricing. Email info@buy-peptidesuk.com with what you need.

Question 9

Is there a minimum order value?

Accepted Answer

No minimum. Free tracked shipping kicks in past a threshold shown at checkout.

Question 10

Which couriers do you use?

Accepted Answer

Royal Mail Tracked 24/48 for standard, DPD Next Day for express. Tracking goes to the email on your order.

Question 11

How are compounds packaged for shipping?

Accepted Answer

Plain, tamper-evident outer packaging - nothing on the outside that says what's inside. Lyophilised peptides hold up at room temperature in transit, so most orders ship that way; cold packs only when the compound actually needs them.

Question 12

Do you ship internationally?

Accepted Answer

Right now, UK only. If you're at a research institution outside the UK, get in touch and we'll see what we can do.

Question 13

Are your compounds legal to purchase?

Accepted Answer

Sold for in-vitro and lab research only. Not licensed for human use, veterinary use or as a supplement. Whether they're legal to import or hold in your country is on you to check before ordering.

Question 14

Who can purchase your products?

Accepted Answer

Adults (18+) buying for legitimate research. Placing an order is your confirmation that you meet that.

Question 15

How should I store peptides and SARMs?

Accepted Answer

Powder form: −20°C, dry, dark - good for 12-24 months. Once reconstituted, drop it to 4°C and use within 28 days. The CoA has the specific storage guidance for that compound if it differs.

Question 16

What is the recommended solvent for reconstitution?

Accepted Answer

Sterile or bacteriostatic water works for most peptides. Hydrophobic ones might need a touch of 0.1% acetic acid or DMSO. The CoA tells you what was used during testing - that's usually a good place to start.

Question 17

What is your returns policy?

Accepted Answer

We can't take back opened vials - that's standard for research chemicals. If something arrives damaged, missing or just wrong, email info@buy-peptidesuk.com within 7 days with a photo and your order number and we'll sort it.

Question 18

How do I contact customer support?

Accepted Answer

Email info@buy-peptidesuk.com, or use the chat widget on the site. Replies usually go out within a few hours during UK working days.
