BioLab

BioLab is the brand behind the Biolab Shop web shops, which sell to customers in the UK, across the EU and in North America. Its catalogue spans food supplements, sports nutrition, nootropics and cosmetics, with a separate line of peptides and other compounds that it labels for laboratory research only. Free Muscle stocks four of those research listings through Muscle Market: Metabolic Boost, BioLab's product name for SLU-PP-332 capsules, at 100, 200 and 500 mcg, and BPC-157 as the hydrochloride salt at 200 mcg, each in a tub of 60 capsules.

About BioLab

BioLab says its catalogue runs to more than 400 products and that it has more than six years of experience in supplementation (home and About pages, checked 2 October 2026). On its Lab Tests page it separates its dietary supplements from what it calls preparations for laboratory testing: concentrated substances that, by its account, are for research and laboratory work only, not for consumption, and of which BioLab is only the distributor. It does not name their maker, so we call BioLab the brand of the capsules listed here, not their manufacturer.

Its research product pages add a notice that the product is neither a drug nor a food and belongs with qualified people in a laboratory. Several unrelated companies and shops trade under similar names, so the tub itself is the practical way to recognise BioLab stock.

How BioLab labels its tubs

BioLab research tubs are purple-blue with a black cap, a BIOLAB band and a white tiger-head emblem. The name bar reads BPC-157 HCL (pink trim) or METABOLIC BOOST over SLU-PP-332 (orange trim), and arrow tags give the strength per capsule and the count, such as 200 MCG/CAPS and 60 CAPS. Our photos show the front only, so look elsewhere on the label for a lot number and expiry date.

What is in the BioLab range

• SLU-PP-332, sold by BioLab under its product name Metabolic Boost, in three strengths: 100 mcg, 200 mcg and 500 mcg, each 60 capsules. SLU-PP-332 is an experimental oestrogen-related receptor (ERR) agonist studied in rodent models; it has no human trial data and no approval anywhere. All brands are compared on the SLU-PP-332 collection.
• BPC-157 HCl, 200 mcg, 60 capsules: BioLab BPC-157 HCl 200 mcg. BPC-157 is a synthetic 15-amino-acid peptide derived from a gastric protein sequence; published work is largely in animal models. See the BPC-157 collection for the other brands we stock.

BioLab's own shop lists more than we stock: a fourth SLU-PP-332 capsule, in a 30-capsule tub under a different name, BPC-157 capsules in arginate (ARG) as well as HCl form at 100 and 200 mcg, and 5 mg, 10 mg and spray listings of BPC-157.

How to compare listings

Because BioLab states strength in micrograms, multiply the per-capsule figure by 60 to get the total content of the pack, then divide the price by that number to compare cost per microgram with another brand or strength. The three SLU-PP-332 listings contain 6 mg, 12 mg and 30 mg per pack respectively. Our article on price per milligram covers the method. Strength is a product fact for laboratory selection, not a recommendation.

Batch testing and certificates of analysis

BioLab is a third-party brand, so its batches are not part of the Janoshik Analytical testing programme that covers the Free Muscle brand. For BioLab products, a certificate of analysis is shown only where BioLab supplies one for the specific batch we hold. Where no certificate is available for a batch, the listing does not claim one. A certificate should carry the batch number, the tested identity of the compound and the measured purity; a generic document with no batch number is not a batch certificate. Our lab tests page explains how to read one and what we can and cannot provide for each brand. Buyers who need certificate-backed batches for every product may prefer the Free Muscle range.

What BioLab says about testing

BioLab says it commissions content tests from independent laboratories, measuring how much of a substance a product holds and not only its purity, and that it keeps more than 500 laboratory reports on the substances it uses. It says each product's current report sits in the product's photo gallery and under a Tests tab on its own shop, and that customers can ask it for the latest.

The BioLab reports on our listings

Listing	Laboratory and date	Label strength	Measured content
BPC-157 HCl 200 mcg	Analiza Białek, Wrocław, September 2022	200 mcg per capsule	195 mcg per unit
Metabolic Boost 100 mcg	Analiza Białek, Wrocław, October 2024	100 mcg per capsule	118.34 mcg per capsule

Both reports name the client as BIOLAB CENTER, used HPLC, and identify the sample by the laboratory's order number and a photograph of the tub instead of a batch number; BioLab quotes the same 118.34 mcg figure on its own product page. Analiza Białek sp. z o.o. is entered in the Polish National Court Register (KRS 0000966168) as a technical testing company, and the tax and statistical numbers on the reports match that entry. Neither report states a purity figure, and with no batch number neither can be tied to the tub you receive. The 200 mcg and 500 mcg Metabolic Boost listings carry no BioLab report.

How to check a BioLab batch

1. Note any lot number and expiry date on your tub, and keep it in its original packaging.
2. Read the report in the product gallery: laboratory, date, label strength, measured content, and whether purity and a batch number are given.
3. Compare dates: a 2022 or 2024 report describes the sample tested then, not necessarily a later lot.
4. Look up the laboratory's KRS number in the Polish National Court Register.
5. Send the product name and lot number via our contact page to ask what BioLab has supplied for that lot. BioLab says it also sends its current report on request.

Where to buy BioLab in the UK: how to check a supplier

Whichever shop you buy BioLab from, check these five points before you order:

1. A batch number and a certificate for that batch. The pack should carry a batch number, and the seller should be able to show a certificate of analysis for that same batch from a named laboratory, with the test date. For BioLab, a certificate is shown where the brand supplies one for the batch we hold.
2. The strength per capsule and the capsule count. With both figures you can work out the total milligrams in the pack and the price per milligram; the comparison table above does this for every listing here that states both. If a listing does not state one of them, ask the seller before you order.
3. Research-use labelling and an age check. A research compound should be sold for laboratory research use only, not for human consumption, to adults aged 18 or over, with no dosing or usage advice. That is how every listing here is sold.
4. Prices in pounds sterling and tracked UK dispatch. UK delivery from us is free and tracked on every order, with no minimum spend, and usually arrives 2-3 working days after dispatch; orders placed before 2pm Monday to Friday are processed the same working day.
5. A clear returns policy. Unopened items can be returned to us within 30 days.

Other brands we stock: Free Muscle, iMuscle, Thoroughbred Labs and Yakka Strength. Compare them side by side in the Muscle Market.

Legal status in the UK

They are supplied to adults aged 18 or over for laboratory research only and are not for human consumption. In sport, both fall under the World Anti-Doping Agency category for substances with no current approval for human use and are therefore prohibited at all times.
