UK Alternative
A UK Alternative to Proforma Peptides
Made in the UK and supplied in solution, so your vials arrive as pre-mixed liquid rather than powder.
Researchers comparing UK suppliers often search for Proforma Peptides, and MY PEPTIDES is worth assessing alongside it. We synthesise and dispatch research compounds from our own UK facility and supply them as pre-mixed liquid vials rather than lyophilised powder, packed cold in a sealed foil pouch. Proforma Peptides is named here only as the term being compared, and we make no claims about it; the sections below describe our own supply format and the questions worth asking any supplier. All compounds are supplied strictly for in-vitro laboratory research use only.
Our research-supply standards
99%+ HPLC Purity
Every batch is verified by high-performance liquid chromatography. The measured purity figure is recorded on the batch COA — not a marketing claim.
COA With Every Order
A batch-specific Certificate of Analysis ships with every order. Sample COAs are accessible from the COA library before you order.
UK Dispatch
Orders confirmed before the daily cut-off ship the same working day from our UK facility, with tracked next-working-day UK delivery as standard.
Research-Only Supply
All compounds are supplied strictly for in-vitro laboratory research. Documentation, labelling and packaging reflect that restriction.

What arrives in the box
When suppliers are compared, the conversation usually starts with the compound and skips the form it arrives in. The form matters, because it decides what has to happen at the bench before any work can begin. Our compounds are synthesised at our own UK facility and supplied in solution, as pre-mixed liquid vials rather than lyophilised powder, so there is no reconstitution step before use. A batch Certificate of Analysis travels with the order, and recent certificates can be viewed in our COA library before you buy. Because a solution is more temperature-sensitive than a dry powder, every order is sealed in a foil pouch with ice packs, boxed plainly, and sent out the same day if it is placed before 3pm on a weekday. All compounds are supplied strictly for in-vitro laboratory research use only.
Solution or powder: what changes at the bench
A lyophilised peptide tolerates room temperature for a while and travels easily, but it has to be reconstituted before it can be used, and reconstitution comes with its own choices: the diluent, the volume, the technique and the record of what was done. Each of those is a point at which two laboratories starting from the same nominal material can end up with different solutions.
A pre-mixed vial moves that step upstream. The compound is already in solution when it arrives, so bench work starts from a defined vial rather than from a preparation step. The trade-off is handling: a solution is more sensitive to temperature than a dry powder, so the chain from dispatch to refrigerator matters more. That is why our vials travel chilled, why orders that come in before the 3pm cut-off leave on the day they are placed, and why the storage instructions on each product page are worth reading before the parcel arrives.
Format questions to put to any supplier
Questions about format are easy to overlook and quick to answer, so they are worth asking before a first order. Is the compound supplied as powder or in solution? If it is powder, what does the supplier advise about reconstitution, and does anything needed for it come with the order or have to be sourced separately? If it is a solution, how is it kept cold in transit, and for how long does the packaging hold temperature? What documentation arrives with the vial, and can you see an example before ordering?
Our answers are on this page and on each product page: in solution; chilled in a sealed foil pouch with ice packs that hold temperature for roughly seven days; dispatched the same day for orders placed before 3pm, Monday to Friday; and supplied with a batch Certificate of Analysis, with recent certificates published in the COA library. Asking every supplier on your shortlist the same questions is the simplest way to compare them fairly.
Frequently asked questions
- Is MY PEPTIDES a good alternative to Proforma Peptides?
- That depends on what your laboratory needs, so we set out the details rather than ask you to take them on trust. MY PEPTIDES makes its compounds in the UK, supplies them in solution as pre-mixed liquid vials, dispatches orders placed before 3pm, Monday to Friday, the same day, and includes a batch Certificate of Analysis with the order. Put the same questions to every supplier you are considering and decide on the answers.
- Is MY PEPTIDES affiliated with Proforma Peptides?
- No. MY PEPTIDES is a separate, independent UK company and is not affiliated with, endorsed by or associated with Proforma Peptides in any way. We use the name only because researchers search for it when comparing suppliers, and any related names or marks belong to their respective owner.
- What does a pre-mixed vial mean?
- The compound arrives already in solution in a sealed vial, rather than as freeze-dried powder that has to be reconstituted before it can be used in an experiment. That removes a preparation step at the bench, and with it the measuring and mixing choices that step involves. It also makes the vials temperature-sensitive, which is why they travel chilled.
- How should pre-mixed vials be stored when they arrive?
- In a refrigerator at 2–8 °C, as soon as the parcel is opened. Each product page carries its own storage instructions, and our storage guide covers the general principles for keeping peptide solutions stable in the laboratory.
- How do the vials stay cold on the way?
- Each order is packed in a sealed foil pouch with ice packs inside a plain outer box, which holds temperature for roughly seven days in transit. Orders placed before 3pm, Monday to Friday, leave the same day on a tracked UK service, so the parcel spends as little time as possible in the post.
