Peptide Dosage Calculator + Chart + Timing (Reconstitution)

Peptide dosing is a delicabte and complicated art. We’ve created a peptide dosage calculator to help you reconstitute your peptides fresh from the source, and then a peptide dosage chart with some common guidelines on dosing, timing, and injection site with all our sources and citations.

Reconstitution and Dosage Calculator

Peptides – the protein’s little brother – can do wonders for our bodies! They can manage our circadian rhythm (1), regulate growth hormones (2), help with weight loss (3), and even make us look younger (4).

Now, before you start flexing your peptide muscles, you need to learn the proper way to reconstitute them. Apparently, a lot of people struggle with this step. Okay, we made up that statistic, but it’s probably close to the truth. The struggle is real, people.

But don’t worry, we’re here to help you navigate this tricky process. It’s like a chemistry experiment, but instead of blowing things up, you’ll be improving your health. Plus, you’ll feel like a mad scientist, and who doesn’t love that feeling?

So, if you want to master your peptide reconstitution, follow our guide step-by-step, and soon you’ll be a reconstitution pro. No more confusion or frustration, just pure peptide power!

How to use The Calculator

While you can go on to use the conventionally manual way to reconstitute peptides, it gets a whole lot easier to use the reconstitution calculator, and get the right dosage!

With our easy-to-use reconstitution calculator, you now don’t have to worry about all the multiplication, division, or unit conversion. All you have to do is just follow the easy steps and BOOM! 

The very first step is to pick the syringe size that you have purchased. It would ideally be either a 0.3ml, 0.5ml, or 1ml syringe. 

The next step is to add the mass of the peptide in mg that you want to reconstitute (This is generally going to be listed on the peptide vial) with the ‘x’ ml of bacteriostatic water in order to get your desirable dosage in mcg.

Once you have put the details, our reconstitution calculator will use its algorithm and devise the volume needed to get your peptides reconstituted!

Make sure you use Bacteriostatic Water

Bacteriostatic water and sterile water are essentially used to dissolve drugs/medications for injection purposes.

Bacteriostatic water is used to dilute or dissolve medications intended for aqueous injection. Its preservative agent (0.9% benzyl alcohol) prevents the growth of bacteria and therefore, extends the shelf life for up to 28 days and enables the withdrawal of multiple doses from a single vial without contamination (5).

On the other hand, a sterile water vial doesn’t contain any preservatives/additives which can keep it free of pathogens for a longer time, thus one will have to use it immediately after opening the seal.

So, if you are someone who has seen the vials of both types of water, I am sure you can now understand why a bacteriostatic water vial contains considerable volume while a sterile water vial contains just a few milliliters.

Despite the favorable safety profile of bacteriostatic water, clinicians caution against its use in pregnant women, neonates, and certain medications. It is also unsafe for injection without a solvent and is contraindicated for intrathecal injections (5).

Where to Buy Syringes and Bacteriostatic Water?

We use 30 gauge 5/16th of an inch (8mm) for our subcutaneous injections, but we recently found a source that sells:

  • Injection syringes
  • Bacteriostatic Water
  • Drawing syringes (To draw the water and insert them into the aliquots)
  • Alcohol wipes

ALL IN ONE BOX! That’s right, no more shopping around. Just order it all from them, and save some money while you’re at it.

How to Store Peptides

Peptides should be stored in a dry, cool, dark place. For best preservation, store at 4°C or colder away from bright light. Dry peptides are stable at room temperature for days to weeks but for long-term storage -20°C is to be preferred (6). 

Contamination with moisture will greatly decrease the long-term stability of solid peptides. A vial containing a peptide should be allowed to warm to room temperature before being opened. After removing the desired quantity, the vial should be re-sealed, preferably under an atmosphere of dry inert gas, and then returned to cold storage (6). An ideal container for peptide manipulation should be clean, chemically inert, optically clear, strong, and available in an appropriate size. 

Glass and plastic vials are generally satisfactory for the purpose, however, care does need to be taken with plastic vials when organic solvents are to be used (6). Polypropylene vials are both strong and chemically inert but if high visibility is required glass is a better option. Please appreciate that peptide in solution can and do adsorb to many materials. This may occur to varying extents being dependent upon factors such as constituent amino acids, vial material, and peptide concentration. 

At high dilution, it is possible to lose large percentages of peptide due to adsorption to surfaces thereby grossly distorting subsequent results. The use of high-quality specialist glass and polypropylene vials can lessen this problem (6). The shelf life of peptide solutions is limited especially for peptides containing C, M, N, Q, and W. To prolong the storage life of peptides in solution, sterile buffers with a pH of around 5-6 should be used. Aliquots should be stored at -20°C or colder wherever possible. 

Avoid the use of frost-free freezers, which vary enormously in temperature during the frequent automatic defrosting cycles. Repeated freeze-thaw cycles are deleterious to peptides (6).

Peptide Dosage Chart with Timing, Injection Location, and Best Stacks

We spent 20+ hours reading research papers, perusing clinical websites and browsing research peptide brands to come up with the ULTIMATE express guide to current up-to-date medical literature on peptide usage, dosage, cycles timing, indications, forms, and studies.

For first time peptide users we know its daunting and intimidating, hopefully this gives you a better idea of what the f*** is going on with most peptides, but remember to exercise caution and consult with your doctor prior to any usage.

Below the individual peptides we’ve added sections on stacks, and we’ve also explained what all the columns mean below. If you want to learn more about an individual peptides click on it or view all our peptide guides below the peptide chart!

The Complications of Dosing Peptides

While there is no fixed dosage of peptides and each peptide accounts for a different dose.

Recommended dosages are usually based on either clinical trials or users’ experience. 

Therefore, if you decided to use any peptide for personal purposes, it is crucial to consult with your doctor/healthcare provider first.

For example, the recommended dosage of BPC-157 is 1mcg to 10mcg per kg of body weight which accounts for 200mcg to 1000mcg per injection. But note that BPC-157 is not approved by the FDA for human use.

On the other hand, TB-500, another potential peptide for quick healing is usually dosed at 7.66mg per week. However, as BPC-157, TB-500 is not approved by the FDA for human use.

So it all differs and the exact dosage can only be prescribed by your healthcare provider.

What Does Studied Dosage Mean?

The studied dose is the amount of a drug/agent which is proven most efficacious through multiple clinical trials. These trials help evaluate the optimum amount of a given drug that has maximum bioavailability and minimum to induce any negligible side effects.

It is therefore extremely crucial to abide by the correct dosage in order to mitigate the risk of developing any significant adverse effects at the expense of availing maximum benefits.

How Did We Find Typical Cycle Length?

Every peptide is cycled differently by various people. Cycle Length usually indicates the time period during which the drug starts showing its effects in the human body. For peptides, we referred to several clinical trials and user reviews to find the exact cycle length of each peptide.

How Did We Calculate the Timing of Dose?

There’s always a specific time for the intake of the drug alongside certain other precautions. With right timings, you can ensure a drug/supplement’s maximum bioavailability. In order to come up with the right time, we referred to user experiences/reviews as well as scientifically proven research.

What Does Use/Indication Mean?

Use/Indication highlights the purpose behind the intake of the chosen peptide. This is helpful for people to identify the most suitable peptide that would work for them and avoid the rest.

What Are the Recommended Forms to Use?

Recommended forms of peptides depend on the vendor as well as on its half life and bioavailability. Some drugs are only synthesized in injectable or capsule forms. Others can come in creams, skin patches, sprays etc.

While there may be different forms of peptide, it is usually the injectable form that provides the maximum bioavailability. However, injectable form is a strong contraindication in people with bleeding disorders or skin infections.

In general, the recommended form highly depends on the peptide that is being used.

How many Days worth does this reconstitute to? If I have a 5mg mass that I need to draw 300mcg doses daily, it tells me the volume to draw based on how many ML of water I use but it doesn’t tell me the quantity of doses that will yield

If you convert 5mg to mcg, it is 5000mcg. So divide 5000mcg by 300mcg.
