Research peptides are synthesised under controlled laboratory conditions, with independent purity verification on every batch. Where a Janoshik report is not yet available, we provide results from other recognised testing centres when available. If no third-party report can be shown yet, the batch is already being tested by Janoshik — samples sent by us — and this page will be updated once further testing has been completed.

  • Correct dosage — what you pay for is what you get

    If you are paying for 60mg, it should be 60mg (or 59mg at worst). As competitor reports show, many peptide brands do not supply the labelled dose. We do not accept that, and we are open about it so you can compare.

  • Why are we telling you this?

    Because we were once in your position. We do not agree with under-dosing or sales tricks that make a product look better than it is.

  • No two-pen extra-value gimmicks

    Some boxes include two pens so it looks like double value. A correct mix belongs in one pen for the proper dose. Splitting across two pens is a sales gimmick — not more product.

  • A 60mg pen that actually lasts

    A 60mg pen from us is typically enough for around 15 weeks at 2mg per week. Many competitor pens only last about a month, and you may need higher amounts simply because you are not receiving what was advertised.

  • Sample mg should match results mg

    The milligram amount on the product should match what testing shows. Label and results should line up.

  • Made to order and stored correctly

    Our pens are made to order at the time of purchase and held in the correct conditions (freezer) until dispatch.

  • Ready-mixed in the box, with Hospira (Pfizer) only

    Every pen arrives already mixed in its box, ready for research use — no preparation needed. Prepared only with Hospira, the gold standard bacteriostatic water, so our pens can be kept for up to six months under correct fridge storage.

Testimonials

What Researchers Say

“Ordered on a Monday morning and it was with us the next day. Plain outer packaging, and the batch COA matched what was listed on the site. Exactly what we needed — will be reordering.”

Daniel R.

Research Scientist

“The COA confirmed the purity stated on the label, and the pricing is fair for the quality. A supplier I feel confident recommending to colleagues.”

Charlotte B.

University Lab Manager

“I've used Swiss Labs Pharma for around two years now. Batch after batch the purity has been consistent, which makes planning repeat experiments far easier.”

Dr. Priya S.

Independent Researcher

“Several orders in now and every one has been dispatched the same day. When I've had a question, support replied quickly and actually knew the products.”

Andrew M.

Biochemistry Researcher

“Clear batch documentation and high purity standards throughout. When accuracy matters in your work, that kind of transparency counts for a lot.”

Dr. J. Thompson

Pharmaceutical Research

“Dispatch was quick and everything was packed properly. Having the certificate of analysis available made adding the batch to our lab records simple.”

Tom W.

Laboratory Technician
