PCT10 is a promo code for Trulab Peptides that takes 10% off. The important detail is what that 10% is calculated on: the discount applies to the cart subtotal, not to shipping or taxes. If your cart holds several vials plus a bottle of bacteriostatic water, the code reduces the combined value of those goods, while any postage charge and any tax line are worked out separately and stay as they are.
That distinction matters most on international orders. International shipping rates start at $20, and that $20 or more sits outside the discount. A cart with a modest subtotal and an international shipping charge will therefore see a smaller proportional saving on the final amount payable than the headline 10% suggests.
The code only counts if it is applied before the order is placed. Trulab Peptides runs a standard WooCommerce-style store, so there are two entry points:
The coupon field on the cart page, behind the prompt "Have a coupon? Click here to enter your code"
The coupon box at the top of the checkout screen
Enter PCT10 in either field and press Apply. Codes on this platform are usually case-insensitive, so lower-case entry should not void anything, though typing it exactly as written removes any doubt. Before moving on to shipping and payment, confirm that a discount line has appeared above the order total. If there is no discount line, the code has not attached to the order, and completing checkout at that point means paying full price on the subtotal.
The strictest condition attached to any Trulab Peptides order is not about the code at all. Products are sold strictly for laboratory research use, for qualified purchasers. The audience is researchers buying peptides for laboratory work, and that framing applies to discounted orders exactly as it applies to full-price ones. A promo code does not change the intended use of the goods or who is eligible to buy them.
Bulk enquiries at Trulab Peptides are handled by email rather than through the standard shop flow, and bulk pricing is not normally combined with PCT10. If you are negotiating a larger order directly, treat the 10% code and any bulk rate as alternatives rather than something to add together. For ordinary cart-sized orders placed through the site, the code is applied in the usual way at the coupon field.
The knowledge available does not state a minimum spend for PCT10, a maximum discount value, a limit on how many times one customer may use it, or an expiry date. Those details are not published in the information covered here, so the safe approach is to check the code still applies at the cart stage on the day you order rather than assuming it runs indefinitely.
Trulab Peptides offers free US shipping on orders over $100. Because PCT10 reduces the subtotal, a cart sitting just above that threshold could fall below $100 once 10% is removed. Whether free shipping survives after the discount is applied is not stated and should be checked on site: apply the code, then look at the shipping line before confirming the order.
If free shipping does drop away, the arithmetic is worth a moment's thought. On a cart a little over $100, a 10% discount saves around $10, which may be cancelled out or worse by a reinstated postage charge. Adding a further item, such as bacteriostatic water for reconstitution, can keep the discounted subtotal above the threshold.
Before placing the order, check three things in sequence: the discount line above the total, the shipping line, and the tax line. Checkout is card-based with secure processing; which alternative payment methods are available is shown at the payment step rather than in advance, so any preference there is confirmed only at that stage.
Delivery terms are unaffected by the code. Domestic delivery goes via USPS Priority in 2-3 business days, orders ship next day, and orders placed before 7am ship the same day. Vials arrive lyophilised, having been held in cold storage, with certificates of analysis available from the in-house lab that tests batches by UHPLC. Per-product storage specifics are listed on each product page and its COA.
