Marcus Reid is a functional medicine researcher, data analyst, and peptide specialist, and one of the people who built MyPeptidePal. The platform exists in part because of the years he spent immersed in clinical literature, real-world protocols, and the kind of hands-on experimentation that most textbooks skip entirely. He is not a physician and does not pretend to be. What he is, is someone who has done the work to understand how these compounds actually function at a biological level, what the research actually says versus what the forums claim, and how to explain it in a way that makes sense to anyone willing to learn. At MPP, Marcus contributed to building the knowledge base, the protocol frameworks, and the research systems that power the platform. His work covers tissue repair, metabolic health, hormonal optimization, longevity, cognitive function, and cosmetic applications. When the science gets complicated, his job is to make it click.

Cardiogen Protocol: How to Cycle It, Timing & What to Expect

A Cardiogen protocol runs in short, defined cycles with a deliberate off-period built in from the start. The oral and sublingual route uses a 10 to 20 day cycle followed by a 3 to 6 month break, while the injectable route runs 8 to 12 weeks with a gradual titration approach and the same extended off-period. Both routes are dosed once daily, and most people using it preventively run one or two cycles per year. The personalized dose depends on the user's goal and delivery route and is built in the MyPeptidePal Protocol Creator rather than fixed for everyone.

Cagrilintide Protocol: How to Cycle It, Timing & What to Expect

A cagrilintide protocol is built around once-weekly subcutaneous injections, run in a slow, deliberate titration that spans roughly 12 to 16 weeks before reaching a stable maintenance dose. The cycle starts low and steps up gradually every four weeks, giving the body time to adapt before progressing. Most research protocols follow the titration with a continued maintenance phase and then a planned off-cycle break of two to four weeks, though some approaches extend maintenance longer without a formal pause. This guide covers how a cagrilintide cycle is structured, what the titration and maintenance phases look like, the principles behind once-weekly timing, what to expect week by week, and the mistakes that derail most protocols, while leaving your specific dose, cycle length, and schedule to the MyPeptidePal Protocol Creator.

BPC-157 + TB-500 Protocol: How to Cycle It, Timing & What to Expect

A BPC-157 + TB-500 protocol typically runs four to eight weeks, with BPC-157 dosed daily and TB-500 dosed two to three times per week on non-consecutive days, both delivered subcutaneously. The cycle follows a loading-then-maintenance shape where consistent early exposure primes the repair environment before settling into a steady rhythm, followed by a two to four week off-cycle break before any repeat round. This guide covers how the combined cycle is structured, what determines the dose for each peptide, what to expect week by week, and the mistakes that derail results, while the personalized dose, injection schedule, and exact cycle length are built in the MyPeptidePal Protocol Creator.

ARA-290 Protocol: How to Cycle It, Timing & What to Expect

ARA-290 protocols are typically structured as defined cycles of four to eight weeks, dosed by subcutaneous injection once daily, with a one-week titration period at the start before stepping up to the target therapeutic range. While once-daily is the standard frequency used in Phase II clinical trials, some protocols use every-other-day or twice-weekly spacing depending on the goal and cycle length. Unlike many peptides that use a distinct loading-then-maintenance shape with different dose levels, ARA-290 holds to a consistent daily dose across the cycle once titration is complete, and clinical evidence shows meaningful benefits can persist for up to four weeks after the last injection. This guide covers the full cycle structure, frequency and timing principles, what to expect week by week, and the common mistakes that derail results, while leaving the personalized dose, exact schedule, and cycle length to the MyPeptidePal Protocol Creator.

AOD-9604 Protocol: How to Cycle It, Timing & What to Expect

An AOD-9604 protocol typically runs 8 to 12 weeks of once-daily subcutaneous injections administered in the morning on an empty stomach, structured as a conservative titration phase in the first several weeks followed by a steady maintenance phase for the remainder. Some practitioners recommend a four-week break after a 12-week cycle, while clinical trials have run continuous daily use for up to 24 weeks without finding a need for breaks. Because the effective dose depends on your fat-loss goal, your preferred delivery route, and your individual response rather than a fixed number that fits everyone, the personalized dose is built in the MyPeptidePal Protocol Creator rather than stated here.

AICAR Protocol: How to Cycle It, Timing & What to Expect

An AICAR protocol typically runs eight weeks, dosed once daily via subcutaneous injection, following a gradual titration shape that starts low and steps up every two weeks until the target range is reached. After the cycle, a four-week minimum off-cycle break is standard before beginning again, with most researchers limiting themselves to two or three cycles per year. The dose for any individual is shaped by their goal, their experience with the compound, and how their body responds, and those variables are what the MyPeptidePal Protocol Creator uses to build a personalized protocol rather than a one-size number.

Adamax Protocol: How to Cycle It, Timing & What to Expect

An Adamax protocol typically runs six to twelve weeks at a once-daily frequency, built around a gradual titration shape that starts lower and builds toward a steady maintenance level, followed by an off-cycle break of roughly equal length. Formulations vary across sources, with some products positioned as a Semax-analog nootropic and others as a growth hormone secretagogue blend, so the goal you are pursuing and the specific product you have both shape how the cycle is structured. This guide covers how a cycle is built, what determines where your dose lands, what to expect across the weeks, and the mistakes most likely to derail a run, while leaving your personalized dose, schedule, and cycle length to the MyPeptidePal Protocol Creator.

Adipotide Protocol: How to Cycle It, Timing & What to Expect

An Adipotide protocol is built around a short, fixed cycle, typically 28 days of once-daily subcutaneous injections, followed by a mandatory washout period of at least four weeks to allow full kidney recovery. Some researchers use a cautious gradual titration approach that extends the cycle to eight weeks. There is no loading phase: the dose stays consistent from day one throughout the cycle. This guide covers how the cycle is structured, when effects tend to appear, what safety monitoring looks like as part of any protocol, and the mistakes that most commonly derail a run.

ACE-031 Protocol: How to Cycle It, Timing & What to Expect

An ACE-031 protocol looks structurally unlike most peptide cycles. Because the compound has a half-life of ten to fifteen days, clinical trials used infrequent subcutaneous injections spaced every two to four weeks rather than the daily or twice-daily schedules common to other peptides, with a twelve-week Phase 2 study design using three total injections as the closest reference point for a full cycle. There is no established loading or maintenance phase. The personalized dose for ACE-031 is built in the MyPeptidePal Protocol Creator, which accounts for your goal type, your injection frequency, and your individual response tolerance.

Semaglutide Protocol: How to Cycle It, Timing & What to Expect

A semaglutide protocol is built around a gradual weekly titration that runs roughly 20 to 24 weeks from first injection to full therapeutic dose, with each step held for four weeks before moving up. Unlike short research peptide cycles, semaglutide is not cycled on and off: the evidence-based approach is continuous weekly dosing, with the dose climbing through several defined steps and then settling into an ongoing maintenance phase. This guide explains how the titration and maintenance phases are structured, what drives where someone lands on the dose range, what to expect week by week, and the mistakes that derail most protocols, while leaving the personalized dose and cycle length to the MyPeptidePal Protocol Creator.

Why 30 mL Bacteriostatic Water Vials Are a Safety Risk (And What Size to Use Instead)

Bacteriostatic water has a 28-day safe-use window after the first needle puncture, and that clock does not stop because you have fluid left in the vial. A 30 mL vial sounds like a bargain, but most peptide users cannot realistically use 30 mL within 28 days - which means the remaining water is either discarded or, more dangerously, used past the safe window. Smaller vials, specifically 3 mL or 10 mL, are the practical safer choice: they match actual reconstitution volumes, reduce cumulative puncture risk, and are cheap enough to throw away when the job is done.

How Long Do Reconstituted Peptides Really Last? Stability vs. Bacterial Risk Explained

Reconstituted peptides do not suddenly lose potency after 30 days - chemical stability data shows they can retain 90% or more of their efficacy for months when kept refrigerated. The 30 to 45-day guideline exists because bacteriostatic water - the preservative used in reconstitution - is only validated to suppress bacterial growth for about 28 days in a multi-use vial. After that window, the peptide may still be chemically intact, but contamination risk climbs with every vial puncture. The two clocks running simultaneously are chemical degradation (slow) and bacterial growth risk (fast) - and understanding which one actually limits reconstituted peptide shelf life changes how you think about storage.

How Long Do Lyophilized Peptides Last? Powder Storage, Shelf Life, and Best Practices

Lyophilized peptide powder stored in a properly sealed vial and kept in a standard freezer at -20°C typically remains stable for two to five years. At ultra-low freezer conditions of -80°C, that window extends to five to eight years or longer with minimal degradation. Refrigeration at 2-8°C is acceptable for short-term storage of six to twelve months, but shelf life drops significantly compared to freezing. Room temperature is the enemy of lyophilized peptides and degradation begins within hours to days at ambient conditions. The recommended approach is simple: keep all vials in the freezer, thaw one at a time before mixing, and keep reconstituted liquid peptides in the refrigerator - a topic covered separately.

What Size Needle and Syringe Should You Use for Peptide Injections?

For most peptide injections, a 30 or 31 gauge, 8 mm (5/16 inch) fixed-needle insulin syringe is the right choice - subcutaneous delivery, minimal pain, and precise dosing from a small barrel. Syringe volume depends on your dose: 0.3 mL for very small draws, 0.5 mL as the most versatile option for common peptide doses, and 1 mL when your volume exceeds 0.5 mL. Matching your syringe size to your dose is just as important as needle gauge - a small dose drawn into an oversized syringe introduces measurement error that a smaller barrel eliminates.

Bacteriostatic Water vs. Acetic Acid: When and How to Use Each for Peptide Reconstitution

Most peptides dissolve cleanly in plain bacteriostatic water, but a handful of pH-sensitive compounds need an acidic environment to go into solution at all. The practical answer is not to switch entirely to acetic acid - that would make injections sting badly. Instead, a small volume of 0.6% acetic acid is used first to dissolve the peptide, then bacteriostatic water is added to reach the target volume and dilute the acid to comfortable levels. Understanding when and how to combine these two solvents is the difference between a peptide that reconstitutes cleanly and one that clouds up, gels, or simply refuses to dissolve.
