Before looking at discounts, it helps to know what sits in the catalogue. Trulab Peptides is a US-based online supplier of research peptides sold for laboratory research use only, aimed at qualified purchasers and researchers. The compliance category is research compounds, not consumer supplements, and the terms state plainly that products are sold strictly for laboratory research use.
The catalogue covers common research compounds along with supporting items. BPC-157, for example, is sold in a 5 mg lyophilised vial. Bacteriostatic water, used for reconstitution, is sold separately rather than bundled with a vial, so a first order usually contains at least two line items.
Vials arrive lyophilised, meaning freeze-dried, which is why bacteriostatic water is a common companion purchase. Trulab holds vials in cold storage to prevent degradation before dispatch.
On quality, the company runs an in-house lab and tests batches by UHPLC, publishing certificates of analysis. Samples are analysed to verify sequence signatures, purity, quantification and sterility, and the company claims 99%+ purity with lab-verified certificates. Per-product storage specifics are listed on each product page and on the relevant COA, so a newcomer should read those pages rather than assume a single standard applies across the range.
The store runs on a standard WooCommerce-style setup, which means the coupon mechanism will look familiar if you have shopped on similar sites. The code is PCT10, and it gives a 10% discount.
There are two places to enter it. The first is the coupon field on the cart page, usually presented as a link reading 'Have a coupon? Click here to enter your code'. The second is the coupon box at the top of the checkout screen. Either works; the cart page is easier for a beginner because you can see the subtotal change before committing to the checkout flow.
Open the shop at trulabpeptides.com and browse by compound.
Add products to the cart, including bacteriostatic water if you need it for reconstitution.
Open the cart and enter PCT10 in the coupon field, then press Apply.
Confirm a discount line appears above the order total.
Fill in shipping details, choose payment, and place the order.
Step four is the one beginners skip. A code that has been typed but not applied does nothing, so the visible discount line is your confirmation.
The 10% applies to the cart subtotal, not to shipping or taxes. Codes on the platform are usually case-insensitive, so capitalisation should not be the reason an entry fails.
Shipping has its own threshold: US orders over $100 ship free, and international shipping rates start at $20. One point is genuinely unresolved in the available information — whether free US shipping remains in place after PCT10 lowers the subtotal below $100. If your pre-discount total sits just above the line, check the totals on the cart page before completing the order, because the answer is not stated anywhere official.
Bulk enquiries are handled by email, and bulk pricing is not normally combined with PCT10. If you are buying at volume, the email route and the coupon are effectively alternatives rather than a stacked saving.
Checkout is card-based with secure processing. Which alternative payment methods exist is not specified in advance; they are shown at the payment step, so you will see the options once you reach it.
Orders ship next day, and orders placed before 7am ship the same day. Domestic delivery goes via USPS Priority in 2-3 business days. International customers pay from $20 upward depending on destination.
For someone new to the category, a workable approach is to choose one compound, add bacteriostatic water if the protocol calls for it, apply PCT10 on the cart page, and confirm the discount line before moving on. Read the product page and COA for storage guidance, and remember the eligibility condition attached to everything on the site: laboratory research use, qualified purchasers only.
