Independently verified
Each peptide in this stack is analyzed by an accredited US third-party laboratory before it ships.
Identity and purity confirmed by MZ Biolabs (Tucson, AZ), a US DEA-licensed analytical facility, via HPLC purity analysis and mass-spectrometry identity confirmation under GLP standards.
Our third-party certificates of analysis are published on our website — no login required.
BPC-15799.43% pure
TB-500 (Thymosin β4)99.42% pure
Storage & handling
Peptides are photo- and temperature-sensitive; handle per standard laboratory practice.
- Lyophilized storage: Keep the sealed vials cool, dry, and protected from light. For longer-term storage, freezing is standard practice for lyophilized peptides.
- After reconstitution: Refrigerate (approximately 2–8 °C) and follow your institution’s SOPs for aliquoting, handling, and disposal. Avoid repeated freeze–thaw cycles.
- Diluent not included: Suitable laboratory diluent and reconstitution supplies are not provided with this product.
- UV-resistant glass vials to help protect photo-labile peptides during storage.
- Tamper-evident seals to support chain-of-custody and inventory controls.
Why source this stack from Sports Technology Labs
Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products. Independent verification of identity and purity is essential for reproducible research.
Both peptides verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.
Freeze-dried into sterile, UV-resistant glass vials and packaged in the USA.
Supports chain-of-custody, label transparency, and batch-linked traceability.
Transparent business, standard payment methods, no misrepresentation.
What is in the Wolverine stack?
This stack, colloquially called the “Wolverine stack,” pairs two research peptides — BPC-157 and TB-500, supplied as separate lyophilized vials. The two are distinct molecules with different structures, described below by identity only.
BPC-157
BPC-157 is a synthetic pentadecapeptide (15 amino acids). Its sequence corresponds to a partial fragment of Body Protection Compound (BPC), a protein identified in human gastric juice. It is used as a research chemical to investigate this peptide in experimental models.
TB-500 (Thymosin β4)
TB-500 is a synthetic peptide analog of thymosin β4, a naturally occurring 43-amino-acid peptide present in many mammalian tissues. Thymosin β4 is characterized biochemically as an actin-sequestering peptide (it binds monomeric G-actin). It is used as a research chemical to investigate thymosin β4 biology in experimental models.
These compounds are supplied strictly as research chemicals for laboratory research. Sports Technology Labs makes no claims regarding their effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
Both peptides are investigational research chemicals. They are not approved by the FDA and are not drugs, foods, dietary supplements, or cosmetics. Marketing them for human use is unlawful.
BPC-157 has no approval from any governmental regulatory health authority for human therapeutic use, and as such falls under WADA category S0 (Non-Approved Substances), prohibited at all times (ref. 4).
Thymosin β4 (TB-500) is associated with WADA category S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics), under growth factors affecting regenerative capacity. Athletes should consult the current WADA Prohibited List (ref. 4).
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
