What a TB-500 dose actually costs

Three things to read off the table

The first is the 2 mg row. A 2.5 mg dose does not fit inside a 2 mg vial, so the whole-dose count is 0 and the entire 2 mg is stranded. Stranded here means peptide that is in the vial and paid for but cannot be drawn as a dose of the size you chose. The waste percentage is marked n/a rather than 100% because a percentage of doses makes no sense when the dose count is zero. There is nothing to divide.

The second is that both the 5 mg and 10 mg vials strand 0 mg at this dose size, giving 0% waste. That is not a property of TB-500. It is a property of 2.5 dividing cleanly into 5 and into 10. Change the dose and the pattern changes with it.

The third is the gap between 2 and 4 whole doses. Doubling the vial size doubles the dose count at this dose, because neither vial leaves a remainder. When both options are clean, the comparison collapses to a straight price question: which vial costs less per whole dose.

Cost per dose is a division we cannot finish for you

The arithmetic is: vial price divided by whole doses. Not vial price divided by label milligrams. Those two numbers diverge the moment a remainder appears, and the label figure always flatters the vial.

This site holds no price data. Vendor pricing for a compound in this category moves, differs by seller, and is not something we can verify or keep current. So we supply the denominator and you supply the numerator. Take the price you were actually quoted for a 5 mg vial and divide by 2. Take the price for a 10 mg vial and divide by 4. Compare those two figures directly.

For the 2 mg vial at a 2.5 mg dose there is no denominator. You cannot express a cost per dose because you cannot draw a dose. Whatever the vial cost, all of it is stranded. That is the case where per-milligram pricing misleads most badly: the vial can look cheap per milligram while delivering nothing at the dose size you picked.

Reconstitution volume does not change the count

Vials of this compound are commonly put into 1, 2 or 3 mL of water. That choice changes concentration, and therefore how many syringe units a given dose occupies. It does not change how many milligrams are in the vial, so it does not change the whole-dose count or the stranded amount in the table.

What it can change is practical waste, which is a separate thing from stranded peptide. A dose that lands on an awkward mark is harder to draw accurately, and residual liquid left in the syringe barrel and needle hub is lost regardless of concentration. Those losses are not in the computed figures above, which treat the vial as a pure milligram budget.

If you are comparing vial sizes on cost, do the milligram arithmetic first and treat the water volume as a separate measurement question.

What this page does not tell you

We hold no reliable human pharmacokinetic data for TB-500. This site therefore makes no claim about its half life, how long it takes to clear, or whether repeat administration accumulates. Every number here concerns milligrams, concentration and volume. None of it describes what happens after administration.

That matters for cost, because cost per dose is only half of a spending question. The other half is doses per unit of time, and that depends on a schedule. We cannot supply or evaluate a schedule, so we cannot turn cost per dose into cost per week or per month.

TB-500 is not approved by any regulator for human use. This page has no medical review. It does not tell you what dose to use, what to expect, what adverse effects occur, or whether the compound is safe or effective. Those are clinical questions and this is a calculator. If you want them answered, ask someone qualified to answer them.

What we do not know

We hold no reliable human pharmacokinetic data for TB-500, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

Which TB-500 vial size is cheapest per dose?

At a 2.5 mg dose, the 5 mg and 10 mg vials both strand 0 mg, so neither loses product to remainder. The winner is whichever has the lower price divided by its whole-dose count, 2 for the 5 mg vial and 4 for the 10 mg vial. We do not hold price data, so you supply those figures.

Why does the 2 mg vial show no waste percentage?

Because it yields 0 whole doses at 2.5 mg. Waste percentage is expressed against the doses a vial produces, and with zero doses there is nothing to express it against. The stranded column carries the real information: all 2 mg is unusable at that dose size.

Can I combine two 2 mg vials to reach a 2.5 mg dose?

That is a handling and sterility question, not an arithmetic one, and this page does not cover it. The table treats each vial as a closed budget. Whether pooling vials is advisable is outside what this site can assess.

Does using more water make the vial go further?

No. Water volume sets concentration, so 1, 2 or 3 mL changes how many syringe units a dose occupies. The milligrams in the vial are fixed, so the whole-dose count and stranded amount stay the same.

How much does a course of TB-500 cost?

We cannot answer that. A course cost requires a schedule, and we make no claims about dosing frequency or duration for this compound because we hold no reliable human pharmacokinetic data. This page gives cost per dose only, and even then you supply the vial price.

Is stranded peptide the same as wasted peptide?

Not quite. Stranded means milligrams left in the vial that cannot form another dose of your chosen size. Separate from that, small amounts are lost in the syringe barrel and needle hub on every draw, and those losses are not included in the computed figures.
