# Peptide Crafters Review 2026: Lab-Grade Lyophilized Peptides, Acetate Salt Standards, and GLP-1 Availability
Peptide Crafters is a research peptide supplier with 92 active listings across 12 product categories. Their platform description is notably precise about intended use: "certified purity reference standards... supplied as lyophilized powders (acetate salts) intended for non-clinical laboratory applications, chemical structure elucidation, and in-vitro method development."
This explicit specification of acetate salt form and lyophilization is meaningful for researchers with specific formulation requirements. Peptide Crafters positions itself firmly in the research-instrument tier rather than the general peptide supply market.
This review is based on verified platform listing data as of July 2026.
All compounds discussed are intended strictly for laboratory and preclinical research purposes.

Company Background
Peptide Crafters differentiates itself through its product specification language. Where most suppliers describe peptides in terms of health benefits or broad research applicability, Peptide Crafters anchors their positioning in laboratory methodology: 'chemical structure elucidation' and 'in-vitro method development' signal an audience of analytical chemists and cell biologists rather than general research end-users.
The 'certified purity reference standard' claim suggests COA documentation practices that align with analytical chemistry requirements. Researchers should confirm batch-level certification details directly with the supplier before ordering for protocol-critical applications.
Their 92-listing catalog across 12 categories places them in the upper tier of platform suppliers by breadth, with strong coverage across healing, cognitive, anti-aging, and metabolic research categories.

Lyophilized Acetate Salt Specification
Peptide Crafters' specification that products are supplied as "lyophilized powders (acetate salts)" is a quality indicator worth unpacking for researchers unfamiliar with peptide salt forms.
Lyophilization (freeze-drying) removes water while preserving peptide structure, extending shelf life and improving stability compared to liquid formulations. Properly lyophilized peptides stored at -20C can maintain stability for years, whereas liquid formulations typically degrade faster and require refrigerated cold-chain shipping.
Acetate salt form is the standard counterion form for synthetic peptides produced via solid-phase peptide synthesis (SPPS). During HPLC purification, the trifluoroacetate (TFA) counterion from the synthesis process is typically exchanged for acetate via ion-pair chromatography. The resulting acetate salt form is:
- •More physiologically compatible for cell culture work (TFA can be cytotoxic at higher concentrations)
- •Better suited for mass spectrometry applications (TFA ionization suppression is eliminated)
- •More appropriate for in-vivo studies in animal models
The explicit acetate-salt statement distinguishes Peptide Crafters from suppliers who may not specify formulation chemistry, giving researchers greater confidence in reconstitution reproducibility and experimental cross-comparability.

GLP-1 Agonist Coverage
Peptide Crafters includes GLP-1 receptor agonist compounds with a noteworthy multi-vial pack format:
- •GLP-1 (Sema) 10mg — 10 Vial Pack at $60 — reducing per-vial cost for labs running longer or multi-subject studies
The 10-vial pack at $60 represents $6 per 10mg vial, which is among the more accessible entry points for semaglutide analog research on the platform. This format suggests Peptide Crafters is calibrated for laboratory environments with ongoing compound consumption rather than single-experiment researchers.
For labs running longitudinal metabolic studies or multi-subject in-vivo protocols with semaglutide analogs, the pack format reduces both per-unit cost and procurement overhead.
---
Bioregulator Panel
Peptide Crafters carries 5 bioregulators at a uniform $55 price point:
| Bioregulator | Target Tissue | Price |
|---|---|---|
| Cardiogen | Cardiac tissue | $55 |
| Prostamax | Prostate | $55 |
| Testagen | Testes | $55 |
| Pinealon | Brain / pineal | $55 |
| Cartalax | Cartilage | $55 |
The consistent $55 pricing across all bioregulators simplifies procurement planning for labs running multi-bioregulator studies. Testagen — a tetrapeptide studied for testicular function regulation and reproductive endocrinology — is a less-common bioregulator not carried by all platform suppliers, adding catalog differentiation for researchers in that specialty.
Cardiogen is similarly uncommon: a tetrapeptide studied for cardiac tissue regulation that complements research on peptide-based cardiovascular protective agents.

Key Value Products
GHK-Cu (100mg) in 8mL Vial at $45 is an exceptionally strong value proposition. Copper tripeptide in 100mg quantities typically commands $80–$150 at most suppliers. The large-format vial reduces per-milligram cost significantly for labs using GHK-Cu in wound healing, skin regeneration, or collagen synthesis studies.
SNAP-8 10mg at $30 is competitively priced for the cosmetic peptide category. SNAP-8 (an 8-amino acid fragment of SNAP-25) inhibits catecholamine release at neuromuscular junctions in in-vitro models, with potential applications in expression line research.
NAD+ 1,200mg buffered in 8mL vial shows discounted pricing in multiple variants:
| NAD+ Format | Original Price | Discounted Price |
|---|---|---|
| 1,200mg buffered 8mL vial | $95 | $75 |
| 1,200mg buffered 8mL vial | $125 | $95 |
| 1,200mg buffered 8mL vial | $125 | $105 |
The buffered, large-vial NAD+ at $75 (discounted) is a competitive offering for labs with high NAD+ consumption. The buffered formulation aligns with the lab-focused positioning.

Anti-Aging Compound Pricing
- •L-Glutathione at $40–$80 (size-dependent)
- •Epitalon at $115 — priced above average, possibly reflecting reference-grade specification or larger vial size
- •FOXO4-DRI at $165 — the highest listed price on the platform for this senolytic; the larger format or higher purity specification likely accounts for the premium
Researchers for whom Epitalon or FOXO4-DRI is a core compound may find better pricing elsewhere. Peptide Crafters is stronger on GHK-Cu, NAD+, SNAP-8, and the bioregulator lineup.
---
Cognitive Peptide Pricing
The cognitive category is lean but well-priced:
- •DSIP 5mg at $30 — market rate; the delta sleep-inducing peptide is a useful sleep regulation and stress response research tool
- •Selank at $35–$45 — anxiolytic heptapeptide with GABA modulation and serotonin turnover effects in animal models
- •Semax at $35–$45 — ACTH-derived neuroprotective heptapeptide with the most extensive Russian clinical data set of any cognitive research peptide; multiple vial sizes available
The price spread across multiple Selank and Semax variants reflects size-based pricing rather than quality tiers, giving researchers flexibility to match order size to protocol requirements.
---
Healing and Recovery Compounds
Peptide Crafters includes the core healing peptides alongside combination formats:
- •BPC-157 — the pentadecapeptide body protection compound; among the most widely studied synthetic peptides for gastrointestinal, tendon, bone, and muscle tissue repair in rodent models
- •TB-500 (Thymosin Beta-4 fragment) — studied for wound healing acceleration, angiogenesis promotion, and actin polymerization effects on tissue repair
- •GHK-Cu (100mg) in 8mL Vial at $45 — the copper tripeptide at exceptional large-format value for wound healing, collagen synthesis, and skin regeneration research
The availability of GHK-Cu in 100mg / 8mL format is particularly notable: this is enough compound for extended multi-arm tissue culture or topical application studies without requiring frequent reordering. Copper peptide at this scale and price point is rarely found on the platform.

Supplier Credibility Signals
Peptide Crafters' platform description includes specific language around compound specification that signals technical awareness of research requirements. The terminology — 'certified purity reference standards', 'lyophilized powders (acetate salts)', 'in-vitro method development' — is precise in ways that vague quality claims are not.
Researchers evaluating suppliers should look for this kind of specificity: suppliers who can name their formulation chemistry and articulate the intended use context tend to maintain more consistent quality standards than those using generic language. The acetate-salt specification in particular demonstrates familiarity with the downstream use cases for research peptides in cell-based assays.
