The peptides we carry.

What each one is, what the research actually investigated, and what still isn’t established. Plain language, sources linked.

BPC-157

often called the “Wolverine peptide” online
In stock
What it is
A synthetic chain of 15 amino acids, based on a sequence identified in human gastric juice. “BPC” stands for Body Protection Compound — a name given by the original research group, describing what they set out to investigate rather than a proven conclusion.
Notable
Unusually stable in stomach acid. Published reviews describe it remaining intact in gastric juice beyond 24 hours, where most peptides break down in minutes. That single property is the reason an oral capsule format is viable at all.
What research looked at
Investigated primarily in rodent models since the early 1990s, with study endpoints focused on the gastrointestinal tract, and on soft-tissue and tendon repair. One 2024 review collected over 130 published papers.
Evidence
Animal research — extensiveHuman trials — very limited
Not established
Long-term human safety, effective human dosing, and how much of an oral dose reaches the bloodstream have not been established. Its proposed mechanism involves promoting new blood vessel growth, which is also relevant to tumour growth — raised in the literature as a theoretical caution, not a demonstrated effect.
Where the name comes from
The nickname came from animal tissue-repair studies, amplified by podcasts and forums. It is not a scientific term.
Formats we carry
Two formats of the same sequence. Oral capsules rely on the acid-stability described above and are the simpler starting point — nothing to prepare. The lyophilised vial is the injectable research format: a sealed vial of freeze-dried peptide that a lab reconstitutes itself with bacteriostatic water before use (sold separately), delivering the peptide directly rather than through the digestive tract. Neither format changes what is or isn’t established about the compound itself.

GHK-Cu

the copper peptide
In stock
What it is
A copper-binding tripeptide (glycyl-L-histidyl-L-lysine bound to copper) that occurs naturally in human plasma. Plasma levels decline with age, which is part of why it drew research interest.
Notable
Of the compounds we carry, this one has the most human data — largely from dermatological and cosmetic research, where copper peptides have been studied topically for decades and appear in commercial skincare.
What research looked at
Study endpoints have included skin appearance, wound repair, and collagen-related markers. Much of the human work is topical rather than injected.
Evidence
Animal research — yesHuman data — topical, real
Not established
Injected use is far less studied than topical. Dosing, long-term effects, and outcomes outside of skin research are not established.
Where the name comes from
Named simply for its structure — GHK is the amino acid sequence, Cu is copper.

CJC-1295 No DAC + Ipamorelin

commonly sold as a paired blend
In stock
What it is
Two separate compounds sold together. CJC-1295 No DAC is an analogue of growth hormone releasing hormone. Ipamorelin acts on the ghrelin receptor pathway. Both were investigated for their effect on the body’s own growth hormone release rather than supplying hormone directly.
Notable
They are paired because they act through two different pathways, and early research suggested the combination produced a larger signalling response than either alone.
What research looked at
Study endpoints centred on growth hormone and IGF-1 levels in blood. Some early-phase human pharmacology work exists for each compound individually; the combination as sold is far less studied.
Evidence
Animal research — yesCombination in humans — limited
Not established
Long-term safety, optimal dosing, and whether the paired blend behaves as the individual studies suggest have not been established.
Where the name comes from
CJC-1295 no DAC is a development code from the company that first synthesised it — “no DAC” distinguishes it from a longer-acting version of the same molecule that isn’t what’s sold here. Ipamorelin follows peptide naming convention.

PT-141

also known as bremelanotide
In stock
What it is
A melanocortin receptor agonist, originally derived from research on a different peptide that was being studied for skin pigmentation. It acts on receptors in the central nervous system rather than on blood flow.
Notable
This is the only compound in our catalogue with an approved pharmaceutical counterpart. Bremelanotide was approved by the FDA in 2019 under the brand name Vyleesi for a specific indication in premenopausal women. That approval is not a Health Canada authorisation, and it does not extend to research-grade material.
What research looked at
Went through formal clinical development, so the human data here is more substantial than for most research peptides. Study endpoints related to central nervous system signalling.
Evidence
Human clinical trials — yesAnimal research — yes
Not established
Research-grade material is not the approved pharmaceutical product, is not equivalent to it, and carries none of its regulatory oversight. Dosing and safety outside the approved context are not established.
Where the name comes from
PT-141 is the development code. Bremelanotide is the assigned generic name.

Bacteriostatic Water

not a peptide — a laboratory accessory
In stock
What it is
Sterile water containing a small amount of benzyl alcohol (typically 0.9%), which suppresses bacterial growth. This is what makes a multi-dose vial usable more than once rather than single-use.
Notable
It is a solvent, not an active compound. It has no biological activity of its own and nothing is claimed for it.
What research looked at
Not applicable — this is a standard laboratory reagent.
Not established
Not applicable.
Where the name comes from
“Bacteriostatic” means it stops bacteria multiplying, as opposed to “bactericidal” which kills them.
