How to Use the Protocol Builder

The builder exists to answer three questions that a single-dose calculator cannot: how many injections a week does this actually involve, what does it cost to run, and when does each vial run out.

Add each peptide with its dose and schedule, and the summary above computes injections per week, estimated weekly cost, and estimated monthly cost. The weekly schedule table lays out which compound goes on which day, which is where scheduling conflicts become obvious in a way they never are in your head.

Cost estimates use the vial price you enter and the number of doses that vial yields at your chosen concentration. That means the figure updates when you change reconstitution volume, because a different concentration changes how many doses come out of the same vial. If you want to sanity check a single peptide's math first, the reconstitution calculator shows the underlying numbers.

What a Protocol Plan Should Answer

Injection load. Compounds dosed two or three times daily add up fast when stacked. Three peptides at twice daily is six injections a day, which is a very different commitment from a single weekly injection. Seeing that number before starting is the point.

Timing conflicts. Some compounds have timing requirements that constrain everything around them. Growth hormone secretagogues are typically taken on an empty stomach and away from other food, which limits where they fit in a day. Stacking two compounds with incompatible timing requirements is a planning problem that only shows up on a calendar.

Vial burn rate. Knowing that one vial covers 10 doses tells you when to reorder. Running out mid-protocol is a common and entirely avoidable disruption, and it is the reason the doses-per-vial figure sits next to the cost figure.

True cost. Per-vial price is misleading on its own. A cheaper vial that yields fewer doses at your target dose can cost more per week than an expensive one. The builder normalizes this to a weekly and monthly number so the comparison is like for like. Current supplier pricing is on the price comparison board.

Limitations You Should Know About

This tool does arithmetic. It does not evaluate whether a protocol is sensible, safe, or appropriate for any person, and it has no way to assess interactions between compounds.

It assumes each vial contains exactly what its label states, at the stated purity. For research-supply material that assumption is not verified by anyone, and if it is wrong then every downstream number, dose, cost, and doses-per-vial, is wrong by the same factor.

It also assumes you follow the schedule you enter. Real adherence varies, and a plan built around six injections a day is a plan with more opportunity to drift than one built around one a week. That is worth weighing at the planning stage rather than discovering in week three.

Frequently Asked Questions

How does the builder estimate cost?+
It uses the vial price you enter and the number of doses that vial yields at your dose and concentration, then normalizes to weekly and monthly figures. Because doses per vial depends on reconstitution volume, changing your water amount changes the cost estimate. This makes vials with different sizes and prices directly comparable.
Why does a cheaper vial sometimes cost more per week?+
Because per-vial price ignores how many doses you get out of it. A smaller or lower-strength vial at a lower price can yield fewer doses at your target amount, making the weekly cost higher than a more expensive but larger vial. Comparing weekly or monthly cost rather than sticker price is the like-for-like comparison.
Does the builder check whether my stack is safe?+
No. It performs arithmetic on the values you enter and has no ability to evaluate whether a combination is appropriate, or to assess interactions between compounds. It surfaces practical planning facts like injection load, timing conflicts, and cost. Safety and suitability are clinical questions.
Can I print or save a protocol?+
Yes. The Print Protocol Card button produces a printable version of the weekly schedule and summary. The builder runs entirely in your browser and does not store protocols on a server, so printing or saving the page is how you keep a copy.
Why does the schedule matter more than the total dose?+
Because schedule is what determines whether a protocol is actually followable. Compounds dosed two or three times daily stack into a large daily injection count, and some have timing constraints such as needing an empty stomach that limit where they fit. Those conflicts are visible on a weekly calendar and invisible in a dose total.
