GLP-1 Research Starter Kit (Semaglutide 5 mg · Bac Water · Syringes · Pads)
Semaglutide 5 mg with bacteriostatic water, 31G syringes and prep pads
Overview
The GLP-1 Research Starter Kit puts a complete first setup for incretin work on a single order: one 5 mg vial of research-grade semaglutide, a vial of bacteriostatic water for reconstitution, 31G one-millilitre insulin syringes with fixed needles, and individually wrapped 70% isopropyl alcohol prep pads. Buying the four separately is the usual stumbling block for a laboratory starting GLP-1 experiments, and this bundle removes it.
The peptide component is the same semaglutide we supply on its own: an acylated 31-residue GLP-1 receptor agonist analog, CAS 910463-68-2, formula C187H291N45O59 at 4113.58 g/mol, with Aib at position 2 and a gamma-Glu-(AEEA)2-C18 diacid chain conjugated at Lys26. It is solid-phase synthesised, purified by reversed-phase HPLC to at least 99% and covered by a lot-matched certificate of analysis.

Diluent volume and concentration
How much of this you add is the whole of the concentration question: the same vial of peptide made up with 1 mL or with 3 mL gives three-fold different numbers. Work it out with the reconstitution calculator before the first vial is pierced.
Certificate of analysis
Every lot of GLP-1 Research Starter Kit (Semaglutide 5 mg · Bac Water · Syringes · Pads) is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Peptide purity: ≥99% by HPLC — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about GLP-1 Research Starter Kit (Semaglutide 5 mg · Bac Water · Syringes · Pads)
What comes in the kit?
A 5 mg vial of research-grade semaglutide, a vial of bacteriostatic water for reconstitution, 31G one-millilitre insulin syringes with fixed needles, and individually wrapped 70% isopropyl alcohol prep pads — everything needed to bring the lyophilized peptide into solution.
Is the semaglutide the same as the standalone vial?
Yes. It is the same solid-phase synthesised, HPLC-purified material we list separately: CAS 910463-68-2, C187H291N45O59, 4113.58 g/mol, tested to at least 99% with a lot-matched certificate of analysis available on request.
Why 31G syringes specifically?
A 31 gauge needle is fine enough to pass through a rubber stopper cleanly without coring it, and the 1 mL barrel with 0.01 mL graduations lets researchers measure the small diluent volumes that determine final peptide concentration accurately.
How much diluent should be added?
That depends entirely on the concentration a given protocol requires, and it is a decision for the investigator designing the study. The kit supplies the tools and documentation; it does not include or imply any preparation protocol, dosing scheme or administration guidance.
Is a certificate of analysis included?
A COA matched to the lot number on the semaglutide vial is available on request at any time before or after purchase, covering HPLC purity and mass-spectrometric identity. The supply components are documented for sterility and specification separately.
