At Puffin Peptides, our research peptides are sourced from Canada’s largest premium peptide manufacturer, then packaged and shipped here in Canada. Keeping production close to home gives us greater oversight of quality, consistency, packaging, and every batch that leaves our facility.
Working with an established Canadian manufacturer gives us clearer control from sourcing through fulfilment. The result is a more transparent, dependable source for high-quality research peptides, backed by batch documentation and responsive local support.
From sourcing to delivery, our focus is simple: premium Canadian research products, reliable service, and a standard of quality researchers can trust.
Unlock deeper recovery with CJC-1295, a long-acting peptide that encourages the body’s natural release of growth hormone. It is often explored for supporting restful sleep, lean muscle development, fat metabolism, tissue repair, and overall physical performance.
CJC-1295 (NO DAC) is supplied as 5 mg of lyophilized powder in a sealed glass vial for laboratory research. Confirm the selected vial and batch details before use.
Most vials are prepared using 2 mL bacteriostatic water unless otherwise noted.
Slowly add the water down the inside wall of the vial and gently swirl until dissolved.

CJC-1295 without DAC is a GHRH analogue studied in short-acting growth-hormone release and pituitary signalling models. The no-DAC format is useful when shorter-duration signalling is the comparison point.
Researchers may use time-course sampling to characterize short-acting GHRH-receptor signalling and pituitary GH release. They may also compare directly with sermorelin when the question is how sequence substitutions change stability or response. They may also keep the no-DAC material separate from CJC-1295 with DAC in labels, protocols, and evidence summaries.
It activates GHRH receptors on pituitary cells and can prompt growth-hormone release. Because it lacks the drug-affinity-complex extension, it does not use albumin binding to create the prolonged exposure associated with true CJC-1295 with DAC. Modified GRF(1–29) is not an approved medicine. Direct human evidence is limited, and it should not inherit the prolonged pharmacokinetic claims or clinical data reported for CJC-1295 with DAC.
“No DAC” usually means modified GRF—not CJC-1295 minus one accessory. The shorthand is common in research catalogues but chemically imprecise. Sequence confirmation is the cleanest way to know which 29-amino-acid GHRH analogue is actually being studied. Sermorelin, modified GRF, and CJC-1295 DAC differ. All target the GHRH receptor, but they use different sequence modifications and exposure strategies. Evidence and time-course expectations should stay attached to the exact construct. Direct no-DAC human data are limited. Human pharmacokinetic findings for albumin-binding CJC-1295 should not be used to fill the evidence gap for a short modified-GRF preparation.

Reviews are checked before publication. Your email is never displayed.
BPC-157 arrived clean and well protected. The 10 mg label was easy to read, and I found the batch details without having to hunt for them.
Quick update on the Tirzepatide: ordering was simple, tracking appeared after the first scan, and everything in the mailer looked tidy.
This was my first time ordering Semaglutide. The strength options were clear and the storage notes were right where I expected them to be.
Short and sweet—Retatrutide was well packed, clearly labelled and exactly as listed.
I took a minute to compare the TB-500 options before choosing 10 mg. The page made that easy, and the parcel arrived in good condition.
Product, documentation, shipping and support answers—without making you hunt through the site.
Yes. Puffin Peptides sources its research peptides from Canada’s largest premium peptide manufacturer, then labels, packages, and ships them from Canada. Product and batch information remains tied to each vial.
No. All Puffin Peptides products are supplied strictly for laboratory research and analytical use. They are not for human or veterinary consumption and are not represented as medicines, treatments, supplements, or substitutes for approved products.
Yes. Batch-specific documentation is published for the applicable product strength and lot when available. Open Batch details on the product page; if a document has not yet been published, contact support with the product name, strength, and lot number.
A lyophilized peptide is a peptide that has been freeze-dried into a powder by removing water under controlled low-temperature and vacuum conditions. This format supports stability during storage and allows the material to be prepared according to the product label and research protocol.
Always follow the storage instructions for the exact product and lot. Unless otherwise stated, keep unprepared lyophilized vials cool and dry, away from heat, moisture, and direct sunlight. Refrigerate prepared vials at 2–8°C and avoid repeated freeze-thaw cycles.
No. The correct diluent, volume, and preparation method can vary by product. Most Puffin lyophilized vials use 2 mL of bacteriostatic water unless the product page or vial label says otherwise. Add liquid slowly down the inside wall, gently swirl, and never shake the vial.
Select the vial strength, enter the planned water volume, and add a target amount if you want a measurement-volume result. The calculator displays the resulting concentration and measurement for laboratory planning only. Confirm the vial label and research protocol before preparation.
