Offer questions
Sale code, 2-for-1 and rewards
What applies today, what is excluded, and what you earn for later.
What is the Solution Peptides discount code for October 2026?
The Solution Peptides coupon code for October 7 to 28, 2026 is AUTUMN. Enter this promo code at checkout for 30% off items outside the 2-for-1 collection. No minimum order is required for this code.
All 2-for-1 products are excluded. The code is valid from October 7 at 12 PM ET through October 28 at 3 PM ET, 2026.
Which products are in the BOGO peptide sale?
BOGO means buy one, get one free. The 2-for-1 collection has 20 eligible products, including Peptide 1 (S), Peptide 3 (R) and Peptide CS. Check each product’s eligible sizes and formats. Add one eligible unit to your cart; the second is included automatically, with no code.
An eligible 10-pack includes a second matching 10-pack: 20 vials total.
No. The 30% code excludes all 2 for 1 products. That includes Peptide 1 (S) and Peptide 3 (R), whose listed sale prices already include the second unit. The extra 5% crypto discount and rewards earning apply to the whole order, including 2-for-1 items.
How does the extra 5% crypto discount work?
Pay with Bitcoin, Bitcoin Cash or Ethereum. The extra 5% discount applies automatically at checkout after the other offers. No extra code is needed.
The percentages apply sequentially. For an eligible $100 item, 30% off gives $70; a further 5% off gives $66.50. These two discounts do not add up to 35% off.
Are rewards an immediate discount?
No. The 5% back is earned in points for a future order. Earn 1 point per $1 spent; 20 points are worth $1 of store credit. This is separate from the extra 5% crypto discount at checkout.
To redeem points, the merchandise subtotal must be at least $100 after discounts, excluding shipping. Pay with Points covers up to 50% of the order. A claimed reward code lasts 24 hours; unused points return to your balance.
Does the headline mean 40% off at checkout?
No. The headline includes savings at checkout and rewards earned for a future order. It is not a flat 40% checkout discount. The 30% code excludes 2-for-1 items, payment discounts apply sequentially, and points have separate redemption rules.
How many vials do the preview prices include?
Peptide 1 (S) 5mg is $39 total for 2 vials, or $19.50 per vial. Peptide 3 (R) 10mg is $99 total for 2 vials, or $49.50 per vial. The optional crypto discount is applied afterward.
The sale runs from October 7 at 12 PM ET to October 28 at 3 PM ET, 2026. The new prices are temporary for this sale. Standard shipping rates apply; free shipping starts at $499. No additional free-gift promotion is included. Products are for laboratory research use only.
