Goal: Support lean muscle development, recovery processes, and fat metabolism research.
- AOD-9604 (studied for fat-loss–specific pathways and accelerated lipolysis)
- BPC-157 (researched for tissue healing, inflammation modulation, and muscle/tendon recovery pathways)
- Tesamorelin (investigated for growth hormone–releasing activity and visceral fat metabolism, particularly abdominal fat)
- CJC-1295 (without DAC) (supports natural growth hormone release pathways tied to muscle development and fat metabolism)
- Ipamorelin (included in growth hormone secretagogue research related to recovery and body composition)
If your goal is clean, lean muscle research with faster recovery and fat-burning benefits, this stack delivers.
CJC-1295 (with or without DAC) triggers natural growth hormone release to support muscle gain and improve metabolism. AOD-9604 and Tesamorelin target stubborn fat while preserving muscle, especially around the midsection.
Paired with BPC-157 for joint, tendon, and soft tissue recovery, this stack helps you train harder, build lean muscle, and recover quicker — without unwanted bulk.
The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.

ALL PRODUCTS OFFERED ARE INTENDED FOR LABORATORY RESEARCH USE ONLY.
All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

The Lean Muscle Optimization Stack is a research-focused bundle designed for labs investigating body composition pathways, growth hormone pulse biology, recovery signaling, and fat metabolism endpoints within controlled experimental frameworks. Rather than studying single compounds in isolation, this stack supports multi-arm study design across three tightly related domains: (1) GH-axis stimulation and secretagogue signaling, (2) tissue integrity and recovery-adjacent pathways, and (3) fat metabolism models often used alongside lean-mass research.
All materials in this stack are provided exclusively for laboratory research use. Any references to “lean muscle,” “fat loss,” or “recovery” describe research endpoints (in vitro markers, animal model observations, or mechanistic hypotheses), not validated clinical outcomes in humans.
The stack consists of:
Important Research Notice: Nordsci peptides are supported by third-party analytical testing (e.g., HPLC and mass spectrometry, as applicable) to validate identity and purity. A Certificate of Analysis (COA) is available per lot to support protocol documentation and internal QC workflows.

In research, “lean muscle optimization” typically maps to a set of measurable, adjacent systems rather than a single pathway. Studies often measure lean mass proxies alongside fat mass proxies, while also tracking recovery markers and endocrine signals that influence adaptation. This stack is organized to support modular study design:
This structure makes it easier to isolate variables: endocrine pulse behavior vs adipose pathway shifts vs tissue integrity signaling. For labs building multi-cohort datasets, that separation reduces noise and improves interpretability.
Lean-mass research frequently intersects with the GH axis because GH release patterns can influence downstream metabolic context and tissue adaptation signals. In this stack, three compounds support GH-axis research design from different angles:
In protocol design, the operational priority is pulse-aware sampling. GH-axis readouts can be timing sensitive, so study windows and collection cadence should be aligned to the model objective.
Body composition studies often track fat distribution endpoints (including visceral fat proxies) alongside lean mass proxies. Tesamorilin is frequently positioned in research discussions around visceral fat metabolism, while AOD-9604 is studied in fat-metabolism–adjacent pathways and adipose signaling models that include lipolysis-related endpoints.
For labs running comparative designs, a practical approach is to separate “endocrine-driven adipose changes” from “direct adipose signaling changes” using distinct arms (e.g., Tesamorilin/CJC/Ipamorelin module vs AOD-9604 module), then evaluate combination arms only after baseline curves are established.
Lean-mass adaptation studies can be confounded by recovery limitations and tissue stress. BPC 157 is researched in preclinical models associated with tissue healing, inflammation-modulation signaling, and muscle/tendon recovery-adjacent pathways. In study design, BPC-157 can be treated as a recovery module to help clarify whether performance or adaptation readouts are constrained by tissue integrity signals.
When investigators use stacks, the objective should be scientific clarity, not maximal intervention. A clean framework is:
This sequencing reduces the risk of ambiguous outcomes and enables clearer attribution of observed pathway shifts.
Reproducible inputs matter when you’re comparing endocrine, adipose, and recovery pathways across cohorts and timepoints.

For institutional research programs, sourcing should prioritize verified identity, repeatable purity standards, and COA access. Nordsci Peptides supports research-grade procurement with third-party testing and lot traceability to help labs run GH-axis and body composition research with consistent inputs.
