Thoroughbred Labs is one of the third-party brands sold through Muscle Market alongside our own Free Muscle range. This collection lists every Thoroughbred Labs product we currently hold: seven single-compound capsule listings and two two-compound packs the manufacturer calls Research Systems. Every pack in our data contains 60 capsules. The range spans peptide-class compounds, a SARM, a growth hormone secretagogue, a PPAR-delta agonist and two newer metabolic research compounds, and each compound has its own collection page where brands are compared side by side.

How to compare listings
Where a per-capsule strength is stated, multiply it by 60 for the total content of the pack and compare cost per milligram against the same compound from another brand. Where the strength is not stated on the listing, the pack cannot be compared on that basis, and the batch certificate becomes the more important document. The method is set out in our price per milligram article.
Batch testing and certificates of analysis
Thoroughbred Labs is a third-party manufacturer, so its batches are not covered by the Janoshik Analytical programme that tests every Free Muscle batch. For Thoroughbred Labs products, a certificate of analysis is shown only where the manufacturer supplies one for the specific batch we hold. Where no certificate is available, the listing does not claim one. A batch certificate should carry the batch number, the tested identity of the compound and its measured purity; a generic PDF without a batch number does not tell you anything about the pack in your hand. Our lab tests page explains what is available for each brand.
Legal status in the UK
None of these compounds is a licensed medicine, none has been assessed by the MHRA, and none is an authorised food supplement. They are supplied to adults aged 18 or over for laboratory research only and are not for human consumption. RAD-140, MK-677 and GW-501516 are named on the World Anti-Doping Agency prohibited list, TB-500 is listed as a thymosin beta-4 derivative, and BPC-157, SLU-PP-332 and 5-Amino-1MQ fall under the category for substances with no current approval for human use, so all are prohibited at all times. Our SARMs research guide gives background on the SARM class.
Delivery and returns
Every order ships with free tracked UK delivery in plain packaging. Orders placed before 2pm Monday to Friday are processed the same working day. EU delivery takes 3 to 7 working days.

Frequently asked questions
Does Thoroughbred Labs supply a certificate of analysis?
Only where the manufacturer provides one for the batch we hold. Thoroughbred Labs batches are not part of the Janoshik Analytical testing applied to the Free Muscle brand, so a certificate cannot be promised for every pack. Where one is available it is shown on the listing and should carry the batch number, the compound identity and the measured purity.
Are Thoroughbred Labs peptides legal in the UK?
BPC-157 and TB-500 are not licensed medicines, have not been assessed by the MHRA and are not authorised food supplements. They are sold in the UK to adults aged 18 or over for laboratory research only and are not for human consumption. Both are prohibited in sport at all times: TB-500 is listed by the World Anti-Doping Agency as a thymosin beta-4 derivative and BPC-157 falls under its category for substances with no approval for human use.
What is the difference between BPC-157 and TB-500?
Both are peptides studied mainly in animal models, but they are unrelated molecules. BPC-157 is a synthetic 15-amino-acid sequence derived from a gastric protein. TB-500 is a synthetic fragment of thymosin beta-4, an endogenous 43-amino-acid protein involved in actin binding. Thoroughbred Labs supplies each separately and as a two-compound Research System pack.
What is a Thoroughbred Labs Research System?
It is the manufacturer's name for a pack containing two compounds, either BPC-157 with TB-500 or SLU-PP-332 with 5-Amino-1MQ, in a 60-capsule format. The pairing is how the product is supplied and is not a protocol suggestion. We do not advise on selection or use; both packs are sold for laboratory research only.
How is a Thoroughbred Labs order shipped and can it be returned?
Orders ship with free tracked UK delivery in plain packaging. Orders placed before 2pm Monday to Friday are dispatched the same working day, and EU delivery takes 3 to 7 working days. Unopened items can be returned within 30 days under our guarantee; opened research materials cannot be accepted back. Buyers must be 18 or over.
