Recommended use: 1 Ostarine capsule + 1 MK-677 capsule + [X] Ashwagandha gummies per day. Do not exceed the stated daily serving for each product.

What is the Summer Stack 2026?

The Summer Stack combines three of our most popular compounds — Ostarine (MK-2866), MK-677 (Ibutamoren) and Ashwagandha — in one cycle. Together they support lean muscle growth, faster recovery and better stress management, making it an ideal stack for building a lean, defined summer physique.

Who is the Summer Stack for?

It's built for anyone focused on recomposition — building lean muscle while leaning out — rather than heavy bulking. Ostarine is one of the mildest, most beginner-friendly SARMs, so the stack suits both first-time users and those wanting a cleaner, recovery-focused cycle over the summer.

How do I take the Summer Stack?

Take 1–2 Ostarine capsules per day with breakfast, 1–2 MK-677 tabs per day (ideally before bed to align with your natural growth hormone cycle), and 2 Ashwagandha gummies daily. The recommended cycle length is 8–12 weeks.

Does the Summer Stack require a PCT?

No. None of the three compounds suppress your natural hormones to the degree that post-cycle therapy is required. Ostarine works selectively on muscle and bone tissue, MK-677 is a growth hormone secretagogue rather than an androgen, and Ashwagandha is a natural adaptogen — so you can run this stack without a dedicated PCT.

LEAN MUSCLE & RECOMPOSITION

Ostarine (MK-2866) selectively binds to androgen receptors in muscle tissue, supporting lean muscle growth and helping preserve mass — without the harsher androgenic effects associated with traditional compounds. A popular choice for recomposition: building lean muscle while leaning out.

ELEVATED RECOVERY

MK-677 (Ibutamoren) stimulates the release of growth hormone and supports higher IGF-1 levels, aiding faster recovery, better sleep and improved body composition. Many users also notice fuller muscles and increased appetite, helping fuel training and growth.
